Hi Hellwyn:

The reason I ask is I do refurbs to Beta's (and vhs) vcr's and would be happy to give this a good going over for you, if you are willing to post it out?That is up to you.I believe most of those belt's and that idler tyre is a bit tricky to get to without removing the cassette insertion mechanism.

Hope this helps.............Kevin

Hi Kevin - I'm in giddy London. Would rubbing those wheels still involve a complicated dismantle?

You can all isregard my last post. I've been to the palsite model list countless times but never noticed it shows the meanings of the letters there...der!

Hi, I am in Australia and have recently picked up an SLHF100E in perfect working order (even all the UV meter Leds working). Just curious as to which country the E model was from. I'm used to seeing the AS Model but not the E.Thanks

Hello all,I have been having some issues posting today so I hope this shows up in the chat thread.There is a few questions I would like to ask. Firstly, ask in my previous post I am still on the look out for a Betamax recorder with stereo sound output (Preferably HiFi but no essential)so if anyone is selling one please, please let me know, I have around £175-£ 200 to spend. Secondly I am currently servicing my Sanyo VTC-5000, it is a great performer, but, like all Sanyo's the rubber tyre on the reel mechanism is starting to perish and crack, it still works but there is an annoying rumble as the cracked tyre drives the reels, does anyone know the dimensions for this tyre i.e. inside diameter, outside diameter and thickness in mm. I know that you cant get replacements anymore so I am looking for a direct replacement.

Hellwyn:

Sometimes the rubber tyres just need refreshing with a fine grade of wet and dry paper. If the rubber is very hard ,stretched or cracked then replacement is the only way to go there.The inner pulley grooves also benefit with a slight abrasive to help the belt's to grip better.Where about's are you?

.........kevin

Thanks Noel. Where would I find a kit? Are there any disassembly instructions anywhere? I wouldn't know where to begin really!

Hellwyn,

It needs a new belt kit fitted. The main problem for that is a rubber wheel on the right hand side of the machine. Changing belts is a bit tricky. You have to remove the load mechanism to do it and also take it apart somewhat to change them.Just take pictures so you can see how it goes back together.

cheers Noel

it's a Toshiba V-S36C

Hi Kevin - not it doesn't accept the tape at all, as if the power's off. BTW it's the MkII C6.

Hellwyn:

Does it accept the tape and then eject it when trying to get it to play?

Dennis:What mode Toshiba is it?they are renound for excessive head wear and also the upper drum, plus worn stretched drive belt's.The 'warm up' could be high esr capacitors in the PSU.

....................Kevin

I have a Sony SL-C6UB that powers up but won't load tapes. Is this an easy/cheap fix? Any how-to guides? I see the problem & solution listed for a few similar models on Palsite, but not specifically for the C6. Thanks!

I have a Toshiba Betamax that still plays although it now seems to need about 5 minutes of "warm up" running time before the picture finally comes on the screen (after this a newly inserted tape will play immediately)...doesn't seem to want to fastforward/rewind anymore (I have a separate rewind machine for just this purpose, and to save on the motor) although this too might be a matter of letting it run for a long time...anyone have any suggestions on how to bring the machine back up to normal working status?

Thanks for the great work with chat page guys.

Martin:

Thanks for your efforts. Interesting too how ONLY the Betamax page is affected.looking forward to the new set up:)

Richard.I currently have a HF100 that has been fully refurbished with great hi-Fi and remote but unfortunately £175.00 will not cover the amount I'm asking for a Beta hi-Fi model, that is complete and with guarantee high quality leads,manual (copy or original) and remote.the reasons are, most beta's you will see now are in a poor state due to rough treatment and not being serviced regularly. The Sony's in particular suffer from very time consuming faults and issues and getting ones with good Hi-Fi is proving a challenge nowerdays.The C9 too can be full of issues and they all need a good refurb now as they will start to play up if not.A lot are faulty and some have missing tuner/timer covers.Sorry to be blunt but I see and work on many.I wish you luck in your search and feel free to e-mail me for any further advice or help.

.....Kevin

Hello, I am based in Stoke-on-Trent, Staffordshire. I own a Sanyo VTC5000 and Sony SL-F25 I realliy like the players I have got, but, I am wanting to get a more advanced Betmax Player preferably something with Stereo HiFi sound like the SL-HF100 or failing the the SL-C9 (I know the C9 is only stereo but I like the look of it) is anyone currently selling one of these models I am looking to spend aroun £175 MAX

Please contact me if you have anything for me.

As stated before, best to use the PALsite link:

Russia certainly likes doing spam. Over 17 thousand on one day. Roll on the new system....coming soon I promise.

Hi, I have just tweaked PALsite's copy of the chat page feed. You should see a LOT less spam if you use that instead of the main page.

http://www.palsite.com/chat_page.py?site=Betamax

I am planning to move to just using this feed for the Betamax page. A full (and searchable) chat page archive is also in the works.

Martin

Derek,

I can help you with some spares for your machines if the postage costs are not too high.

See betaheaven.com

regards Noel

Rumen:

From your description it sounds like you have solenoid issues for the pinch roller and maybe eject mechanism and also the forward tension is maybe too high,back tension too severe or the pinch roller needs replacing,causing your damaged tapes.

.Kevin

Hi Kev

I've bought some "new, old stock" parts already (including and idler & pinch-rollers) just in case, and I'm keeping my eyes peeled for any other bits including machines for "scrap". I now have over 150 tapes which I'm slowly archiving and indexing - which is definitely a labour of love...! At least once I've got them transferred to PC I can skip through them digitally to archive the content, rather than having to play and use search (thereby wearing my machines out even more!). Derek.

DerekA:

You will have to search long and hard.Most genuine parts will be new old stock.You can still obtain belt's and some parts are around usually owned by those getting out of the repair business on E-bay.

Good luck...........Kev

Hi I'm in the UK (Cumbria) and now have 5 working Betamax machines including a couple of Sony SL-HF100s, a couple of Sony SL-F1UBs (with TT -F1 Tuner/Timers and HVC-2000 and HVC-4000 cameras) and a Sanyo VTC-9300P. I've had the VTC-9300P since the late 80s but the others are recent acquisitions that have all required work - including full PSU overhauls for the TT-F1s amongst other things!! Once I get sorted, I'll post details of the repairs I've had to do to get these up and running. The SL-HF100s both have faulty VU meters so I'm thinking of designing a replacement for these, but I'm also looking at sources of spares. I need a clock timer display for one of the TT-F1s as the vacuum pip was smashed off mine in transit, plus are video heads, belts, idlers etc still available? Any help or advice welcome!!

Derek.

Hi guys, I've got a VTC5000 Sanyo Betamax player for sale. It originally came from Kev in 2010 and it's worked flawlessly for me ever since. I've even lent it out to people to copy their tapes.

Only looking to sell because I need the cash. Offers around £120

Jeff:

I have e-mailed you regarding the Sanyo parts.

.....Kev

Hi kevin having taken a closer look of the piccys, on the F30 page.The transport mech seems to be the same.That Left gear is intact.The "Tray"that the cassette sits on was Slightly out of square.I adjusted it by taking of that Left hand gear and moving the tray into the right Posn.Then put back the gear.The tape know loads into the machine OK.But there this delay before the threading starts.

jeffoldbean.

Jeff;Whatever you do DON'T open the side cover to the geared tape insertion mechanism.It takes some time to get the alignment right if you put it out.TRUST ME.

I have never seen inside the F25 so don't know if it's the same as an F30 or C30. I would vere towards the F30. The tape loading would be identical I would think.

.....Kev

Hi Kevin I will look into This.I didn't Know about The F30 Piccys.This machine is the SLF-25UB.They have a common Transport.Also I didn't want to take a look inside the gear box.How do you remove the shiny metal top plate.There is a lip on it, that helps to hold the gear box cover on.Which is held with black plastic "sprigs" Lugs?

jeffoldbean.

Jeffoldbean.

AS for your F30 you will need that gear replaced or repaired. The broken tooth is common on that model.That could be why you have the hesitation before loading.

................Kev

Hi Kevin,I live in Leeds "ENGLAND".

Jeffoldbean:

Where abouts are you?

.....Kevin

Whoops!!!! Very sorry Kevin Lambert.Not Keith.

jeffoldbean.

Hopefully Keith Lambert. May Know where I can get a set of belts for a Sanyo VTC 5000. Maybe a pinch roller, and a pendulum assy.My friend Who I have stayed with over the holiday period has this machine.It played tapes with good sound and vision.But the one inch main drive belt.Snapped after 28 yrs, say.Hence my post.

jeffoldbean.

SL-F25UB sorted out a loading problem.By adjusting the position of the lefthand cogged lever of the Loading mech.It was out by a tooth.Throwing the casstette out of square.However when the tape is in the machine. The Threading Process does'nt start immediatley.Sometimes there is a clicking noise, from the threading clutch assy.Before the thrading motor starts.Any ideas.

jeffoldbean.

David:

The 'bullet noise' you describe i take it is 'drop out'.(Small white horizintal flashes).If it was static noise you would see it all over the screen sporadicly.If it's 'drop out's' then that part of the tape is missing oxide so the vcr tries to cover this up with it's "drop out compensator" and are random flashes.You can slightly adjust these to remove more of the white flash but be careful as if you do it too much the picture can jump at any sign of excessive drop out or be totally obliterated by correctitive compensation.When you deliberatley off track the recording the white noise you see should be thin and not have fold over or comet tailing at all.If the picture jumps when offsetting the tracking control ,it's slightly too much compensation.

As for your comment on the Sony SLHF950. Sony added a plastic oblong stip that touches the top front of the drum and also the cassette housing flap,that was it.

What make of Beta vcr do you have? Some are slightly better at covering up 'drop out's' than other,but you can get them all to do a pretty decent job.If the early tapes you are using are excessively worn ,there is'nt much you can do to make them look perfect.

.................Kev

David, I am not familiar with the static electricity issue you are experiencing but can only assume it may have something to do with friction between the tape and a static object in the machine.My first suggestion would be is to wind and rewind every tape a couple of times and see it that works. Secondly, test that all metal parts in the machine are 'grounded'.And what do you mean by 'bullet' noise?

Hi everyone,

I am transferring old Betamax tapes (1981-1989). I have noticed a build-up of static electricity while playing back the oldest tapes, leading to excessive bullet noise. Newer tapes don't seem to have this problem. At the beginning of a tape, little bullet noise is visible. As the tape progresses, bullet noise increases.

I have read this is a known issue in the SL-HF950: http://www.palsite.com/950tech.html#static. Sony supplied an earth kit to solve this issue, but it's no longer available. Does anyone have any further information about this so that I can replicate this solution?

As an alternative, would it help to put old tape into a new cassette housing? Newer Betamax tapes from Sony are grey rather than black. Does this help to avoid static build-up?

Many thanks in advance for any help!

Thanks,David

Hi All,

I have a Sony SLHF100AS which gives a black and white picture. When the fault first started it seemed to occur once the machine warmed up but now is a constant fault. I have tried changing many caps on the YC28 board but seem unable to resolve the issue. Had anybody had the same issue and been able to resolve it? Ive been searching through all the chat page history and seen the topic raised a few times but no responses.

Thanks

Jan,

I am interested in seeing a picture of that machine and what the differences are. I had a few of the M30 machines which have the still slow motion and playback affects like a Sony SLC9. (At least fwd motion)

Please send them to my email address at my website betaheaven.com

regards Noel

Hi, I don't find the Sanyo VTC-M35 on your page. It looks a lot like the VTC-M20, but with some differences. I got a picture of mine if you want it. This was bought from me in the mid 80's in Norway.Regards Jan Andresen

hi good your product, I wanted to ask for help, I'm from chile and I have a Sony Betamax SL-HFT7 have one gear with one of his broken teeth, it is possible that I can get that spare please ... best regards

Pete,

See betaheaven.com and contact me for some help with your machine.

Cheers Noel

Sanyo VTC 9350Needs new belts and idler tyres. HELP

Is this a Betamax site or a political campaign site?

Thanks, Kevin. Unhappily, without a service/repair manual, I have no idea how to find where these are.I searched for a manual but the only site which suggests is available haven't replied to a request for same.

Pete:

Sounds like either the tape loading or lacing switches need adjustment or are faulty.

...............Kevin

SONY SL-T50ME "CASETTE INSIDE" lamp blinking.Attempt to eject a non existent cassette prompts several cycles of a belt drive to a small plastic clutch which appears to do nothing?I can see no obstruction broken tape, etc., to cause this fault.Any suggestions as to where the faulty sensor(?) might be?

Michael, I cannot imagine the lens from a Betamovie will be removeable per se, let alone something an adaptor is available for! - What makes you think this is possible?

I would like to remove the primary lens from a Sony BMC-110 (for use as a macro lens on my Olympus Om1/Om2 using an available adapter).

Could someone tell me how to remove this lens?

I will happily reward anyone who can offer a successful means to do so with what remains of the BMC-110, for free - and I'll pay the shipping. This camera is clearly in mint condition. The only requirement I ask is that I am able to use the instructions offered to actually remove the lens. That done, the camera is yours (if you want it).

Thank you in advance for your time and expertise, michael

BjornIt would help if you can give your locationCheers Noel

Good evening, I have been absent from this page for a couple of years now. Concentrating on other things, but am pleased to confirm that I still service Betamax machines. I mainly specialize in Sanyo Betacord machines, but can also do some Sony machines, especially fixing the C9 DC2DC converters which have caused many some difficulties. Anyway, I wont be posting often, but feel free to email with any questions, I still have some schematics. I am however, after another machine is anyone has one they want to sell on.

Hello, my name is Guido and I live in Switzerland. Thank you very much Alan and Martin for the beautiful and useful site you are running! Your work is amazing. I'm sorry for my mistakes, i'm not english mother language.

I am the owner of a Sony Betamax SL-C9 unit which is perfectly working and in excellent conditions, with the original remote control Sony RMT-212. I'm going to sell it.

If you are interested or do you need more informations you can contact me at [email protected]

Feel free to ask any information. Thank you very much!Guido

Hi,

I am trying to find out information on the procedure for setting back tension on a Sony PVW2600P SP betacam machine. Does anyone have a service manual that they could copy that section from?

cheers Noel (normally on the Betamax page.)

That's good news Erik, I'm pleased for you. Your Tech did well.

I am thrilled to announce that my beloved SL-HF150 finally came back to life! :-)It was indeed the STK5443.The ones my tech tried on were used and probably faulty as well. As soon as he put in the n.o.s. one i got on ebay the machine worked again!I want to thank everybody for the support! :-)

Starfish, try Jaycar.

Koalabear, it could simply be that your heads are clogged. Easiest solution is to find a good quality tape and let it play for an hour or so. Pretty good chance video will return. Don't use a cleaning tape, they do more harm than good.PS, a koala isn't a bear ;)

Koalabear:

Also a common issue with the Hf100 is a breaking of the solder around the BNC socket where it connects to the circuit board.Move this socket up and down gently with your output wire connected and see if a picture appears.

......Kevin

koalabear,try this for starters.Use this other beta video connected to the SLHF100, video out to video in.With SLHF100 set to the AV I/P.Video out connected to your Telly.Then play video, to see if you get anything on the Telly.This would prove the replay video cct of your SLHF100. Loss of replay video can be caused by the ACE Head being worn.It would mean changing it.If you can get one.

jeffoldbean.

Koalabear: I would try cleaning the output socket with compressed air and contact cleaner first.If that does not work then next check would be for cracked or dry solder joints on the video out board.

I have a Betamax SL-C35AS in great working order. I am wanting to transfer my beta to VHS but can't find my audio cable. Where can I get a replacement. Thanks

Glad I found your site, I have a SL-HF100 Sony Beta PAL unit. I had this unit in the UK and also use it in the USA where I now live (I have a PAL-NTSC converter) it has worked great, I used it to transfer some old beta tapes. It has been stored for over a year, i took it out today to convert more it worked great for about an hour, then I lost video output. Audio is fine, I tried another PAL VHS machine and it works fine, so it is the VCR not outputting. As I am now in the USA (I can't find anyone who will work on a PAL unit) Any suggestions?, any of your readers suggest anything, I can fix at component level no problem, but I have no schematics, It is probably a CAP dried out? Or I can ship and pay someone to repair, it's a fine unit and hate to chunk it. Any help appreciated :)

The answer to your query ,if you are referring to a twin format vcr is no.The portable camcorder VHS market had the VHS-C mini tape that took an adapter so you could fit it into a normal size tape and play in a VHS vcr.This, I believe it what people are thinking of.You can play your Beta tapes through a good thoroughly overhauled Beta vcr and copy to VHS/DVD/PC or whatever you wish. It's the ONLY way I'm afraid.

....Kevin

HELLO FELLOW CHATTERS THIS IS MY FIRST TIME CHATTING. CAN ANYBODY ANSWER THIS FOR ME. BACK IN THE LATE 80s OR EARLY 90s on qvc they where selling a vcr that would take a beta tape and transfer it on to a vhs tape. i have asked people did such a device exist and nobody i know can remember this. did such a vcr ever exist.

Erik,

Don't give up with your hifi beta. Sometimes, feeding the VCR with an external PSU is the only way to spot issues. But it has to be performed carefully, previously checked the exact voltages to supply with the help of a service manual. If not, more components could be damaged.

I would try to check the whole main DC path searching for short circuits or opens. This might be caused by a cold joint, a connector, an open N type fuse or even a fusible resistor. Some videos have a sub-PSU block (some zener+transistor or small regulator) on a different board, but I am not sure it is the case of the HF150.

The PSU can also be checked in an isolated fashion, but probably you should have to "crank" it with a logical level (usually low) in the specified pin/connector. For example, C30s' PSUs work this way, but they don't usually suffer from "blackouts" as other beta models.

With some patience, a service manual and a multimeter your machine can be rescued.

Hi Noel (and everyone else). I read your message just now and i'm contacting you on your site, but i also write here in case someone else wanted to jump in with any useful tip.The situation didn't change. My tech still has my SL-HF150 and doesn't seem to have any luck so far. He said the problem is the STK-5443, and that he changed two that he got from his parts suppliers, but it seems they both were faulty because the VCR was still dead with both of them. He invited me to look for this part on my own.There is a complication though. In the first months he had my VCR, he said that bypassing the power section with an external power supply, he could make the VCR work, and it worked fine. Now though he said that even with the external supply, it doesn't work anymore. He keeps on saying that it's all because of the 5443, but my doubt is that in the meantime something else might have broken...I am starting to be a bit pessimistic about the whole thing...

No Betamax that I know output separate Y and C channels, so composite is the only way to go. You could use a composite to S-Video converter cable, but it'll only give you a composite output, not S-Video.

Sorry to be the bearere of bad news but they never made an ED Beta in PAL. They were an NTSC only creature. The best PAL Beta machine is the Sony SL HF 950.

i search to find pal ED Beta. i know it is verey hard to find it.

hi..i have sony beta model sl-800me, it works,but,the picture not exellent,(some one change the elecrtic adjusts) ineed to repeat it same original electronic adjusts knobs

Sorry for flooding. I was able to remove the board, the items labeled Q2 Q3 Q4 and Q5 get very hot when both motors are spinning (this is what happens when you turn the VCR on). I've marked them on the pictures. They might be faulty, but are they the cause of the problem or do I need to look for Q010 and Q011 again and replace them? See: http://imgur.com/a/Q0vVv

Ok, I found Q0010 (on the right of the small box on the left), but Q0011 is nowhere to be found yet. The smell and heat is coming from the reel motor print, but I can't really seem to remove it? Can't find how to remove it in the service manual, it isn't mentioned as a separate part. SS-11 print seems in working order, doesn't generate heat, doesn't smell, all fuses are ok, all caps seem ok.

There is no obvoius reason why the C9 is doing this. I've made some hi-res pictures of the SS-11 board, have a look at: http://imgur.com/a/dwKZY Also I still can't find the transistors I'm looking for, could anybody point me where they are? I don't see any capacitors leaking, they still look ok to me. I'll try to test them with a multimeter, if they hold any charge at all.Thanks in advance!

I'll try to find out where the smell was coming from and if I can find the transistors mentioned, thanks. I just repaired one of my SL-HF100 machines, that was a lot more doable than I thought once I had the service manual. I do have some experience in repairing Video 2000 machines, but Betamax is a whole different ball game. I also have a (repaired by someone else) HF100 that plays well until you put a Hifi tape in it: there is no sound at all, until you switch back to the linear audio track (if available, on most prerecorded videos it is). Any idea what that might be? It plays brilliantly in mono, doesn't do a thing in Hifi (sound wise).

Irix, this "except for a stinking electronic smell and even a small puff of smoke." makes me think it is more likely to be a capacitor that is leaking, a common problem with Sony.It is impossible to second guess which or how to fix this without examining the machine.Do you know anyone with electronic knowledge that may be able to help you?

Irix,I recall seeing that failure on a C9 long time ago. I am not sure if a fuse was causing that issue or other electronic stuff. There are some of them along the servo board SS-11 (one is under the PSU assembly).I guess that "mute transistors" are Q010 and Q011 at SS-11 board. They are labelled as "C2785", but you can order them by 2SC2785 (they are not so expensive and still available).

Good luck!

Hi,

I'm having a problem with my SL-C9, when I turn it on the left reel starts spinning exremely fast and will continue to do that, even when inserting a tape. When the tape is inserted it will act normal, except for a stinking electronic smell and even a small puff of smoke. It still works though, but I don't want to turn it on again until fixed.

This might be this problem:Reel spools running continuously.This can occur when one of the reel motor mute transistor fails.

But what exactly is the solution and where to find these transistors? Maybe a parnumber that is in the service manual would help?Thanks!

Hi All, I am searching for Sony SL-C9 Service manual in PDF. Thanks, Jiri

Hi Luke:

It sounds like you have excessive wear to the reel spool motor bearing.Also check that the pendulum idler gear arm hasn't got the extended piece on the end that stops this from contacting the reel spool gear(left spool) on ejection.If it has it can be trimmed off.This is common to the C30 too.

.......kevin

I have a number of (mostly used) Beta tapes and some Sony casstte recorders which have been unused for some time. Should I bin them or would anyone like to collect them from Northampton?Dave

I have a Sony SL-C40ES Betamax that I'm having some trouble with. It loads and plays tapes fine but if I play a tape for a while (probably an hour or so) or when the unit is 'warmed up' , it doesn't spool the tape back into the cassette fully when ejecting, causing a loop of tape to hang out when removed from the machine. It works fine when the machine is 'cold' though. Can this be fixed? I'd like to try and do it myself or want to obtain any replacement parts to do it if possible.

Erick I am on holidays in UK at the moment but when I get back to Australia I could send you scans of the SLHF150 power supply and control circuit.Email me through betaheaven.com.Cheers Noel

OK Erik, no luck. Maybe the problem is within mains transformer or a previous stage to the regulator. However, I recall that power supply to be relatively simple (it was like a dual linear PSU with two rectifier bridges and two or three main supply legs).

Please post the solution once the VCR is working again. Encourage your tech, that machine is worth repairing :-)

Regards, Gabriel

Thank you Gabriel. Unfotunately the tech still didn't have any luck. Fuses were ok, and he changed the regulators, but the VCR is still dead.He tried bypassing the problem and tested the VCR with an external power supply, and that way the VCR works perfectly.He said at this point he would need the schematics of the power supply section of my specific model ( SL-HF150 ).I should be able to get some scans from a friend in these days. As soon as i have them i'll give them to my tech and then we'll see what happens.

Hi PAL betaphiles

Seeing as this is PALSITE for PAL vcr owners can i suggest the prolific US spammers go to an appropriate site for their entertainment?

Hi,

I guess a few of us may have a broken tooth on the loading gear of our old Betamax machine. I've fixed mine using a product called Bondic (you can search the web for this glue). My steps are:

1. Clean the broken wheel with detergent2. Put a few layers of Bondic around the broken tooth to build some thickness3. Use a Dremel to shape the tooth

So far this product is having a solid bond with the copolymer wheel and my VCR is working like a charm again... No more cracking sound at loading and the cassette ejects in the correct path.

Hope this is useful.

Kent

Regarding problems with dead HF150s:

Change regulator STK5443 on PSU. Reference STK5441 is compatible. Also, check the small "N-type" fuse N25 on regulator board for open circuit.

Hope this helps,

Gabriel

The latest spam seems to be coming from YAHOO.com;

I have a similar problem as Gerard!After 2 or 3 years i've not been using my SL-HF150, the other day i tried turning it on but it was dead. The on/off switch green led was dead, as the whole mechanical part, who was totally silent. Only the display would work, but the VCR won't load anything.Is there anyone with the full schematics of the SL-HF150? I have the schematics of the SL-HF100, but my tech said he needs the schematics of my specific models to know the exact values of the components etc...

Hi Gerad1960:

I have found usually problems with non illuminating Power LED's is either because the LED had a dry joint of the associated board is cracked.Failing that the LED itself has gone bad.

Gerard, you can download a service manual for a HF-100 here:http://freeservicemanuals.info/en/?search=sl-hf100&brand=Sony&sorttype=asc&sort=typeaThe model is pretty similarly, certainly in their powersupply and it may just have the right information for you.

Goodday to you all Sony guy,s i have one problem with my SL-HF150 the green led in the on/off switch is dead.I have repaired sony betamax machines in the early 80,s like the models C5 / C5 / C7. Does anybody know if this is a capicitor problem?And which capicitor is causing this problem ?

I hope to hear something because i don,t have any service manual.

Best regards Gerard.

Thanks a lot Martin, this Beta corner is worth keeping.

By the way, I have observed that spam is always providing a link. Have you tried blocking the "http" word? Maybe it would be too aggressive for real users, but I think it would block near 100% of spam.

Please keep doing that hard work :-)

Martin:

ALL your efforts are appreciated.Let's hope it stays like this :)

Well this is most unfortunate. Last Friday I was just starting to work on a spam filter upgrade, come Monday they'd beaten me to it. The new filter is now in place and would have caught the weekend's mess.

The issue has been that the latest spam entries were all in a different language, and so the old filter failed to trip. The new filter will hopefully fix this.

As the filter gets more and more aggressive, I am always worried it might block a legitimate poster, please let me know if you think your posts are getting removed.

Where I can buy heads for SL-HF950 Betamax video?
