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.

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?

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.

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.

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.

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 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?

notreplythismail@ggmail.com

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 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.

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.

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 :-)

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,

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.

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?

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.

BlankMinds,

I don't know much about american beta models, but I guess the SL-2710 shares the very common 711B chassis. The eject assembly on these models is sometimes prone to fail due to a broken gear on the left side of the machine (side of Power button). The seat of this gear can be fixed with some epoxy glue, but the whole cariage has to be realigned.

You should take that assembly out of the machine and examine it thoroughly.

Good luck,

Gabriel

Harry,

Probably your F30 has some kind of misalignment on the CTL head or a bad/leaky component on the capstan servo section. A hardened pinch roller can also lead to this symptom.

First thing to check is cleaning the whole tape path, including the CTL/audio zone. The pinch roller should also be removed and cleaned. Sometimes you can "refresh" it by sanding the surface with a soft sandpaper (with number 1600 for example). Do not apply alcohol on rubber surfaces.

Don't attempt to adjust the tape path height posts unless you really know what you are doing. It is advisable to have a CRO and a service manual to perform this operation.

Hope that this helps,

Gabriel

Been wondering if you guys here only only deal with beta video as a hobby or do you enjoy other things?

I also play with vintage radios and audio, I am currently restoring a 1940's radio.

Hi. My parents wedding video is recorded on a L-250 Beta Sanyo Video Cassette. How can I go about in having it switched to DVD format? If not possible, what kind of player should I try and buy so that we can at least watch it that way? All help is appreciated. My parents just had their 30th Wedding Anniversary this past January. Thank you all for your help, Miriam.

Hi --

Broke some part of the cassette carriage on my Sony SL-HF900 years ago when I first got it (used), I suspect by pushing too hard on the cassette. It was basically in perfect condition when I got it, and is a wonderful machine. I still have plenty of Beta tapes packed away, and would like to get the Sony humming again.

So -- the obvious question -- where do I get cassette carriage parts for an SL-HF900? Are they still sold? Are there other models (of which I have at least a couple) that could be cannabalized? Other options?

I'm new here, and would greatly appreciate any information or suggestions of any kind. ("Don't push so hard on your cassettes" has already been duly noted…) Thanks in advance for any assistance!

Hi Joe

i am not a expert on Sanyos. But i did spend a lot of time on fixing old Beta and VHS machines. If the picture looks like the youtube video you linked, then it could be dirty and very contaminated heads.

This is how i clean video heads, but it will grind a little on them. Use a small post-it piece of paper and tear of the glue part. Then fold it, and dip it in 99% isopropanol. Then you shake off any loose fluids. And then you press the soaked paper very delicate against the head thats peaking out from the slot, slowly rotate it back and forth until (feel the small resistance) no more black stuff is coming off. Repeat the process with the other head. Repeat again and again. Never use cleaning tapes. That stuff belong in the trash. Let it dry for 5 min. Insert a good quality tape. And run the machine in play and pause. If the picture is clean. Then success, and start playing the tape.

70% Iso is not good enough if you ask me. It might solve the problem if the heads are not that contaminated. But 99% is the way to go.

Good Luck

Joe,

Your video heads are already clean. At this point, don't focus too much on them because you may have a different problem, like a tracking issue, a failing PSU, a video signal problem or a tape path misaligning. However, you should discard more problems just by renewing the whole belts kit (they are critical in their gauge and nowadays not too easy to find). The pinch roller should also be checked.

After that, I would track the problem with a CRO, searching first the RF video signal in the intended test point and then the tracking CTL signal.

I wouldn't attempt to twiddle too much with certain mechanical adjustments, like the back tension or the stationary heads height/tilt. Sometimes the remedy is even worse than the problem. These videos are robust but delicate with some adjustments.

Good luck!

Is the picture coloured but very messy and bleeding to the right of white objects?Yes exactly, it seens like up and down image is a little bit clearly and in the middle simply it cant see absolutly nothing.Sometines it seen like i could see a little colour but the most of time i only can see black and white.Since 1985 this video has the original heads, so i think it is damaged and need to change, but i dont know where i can buy it

Hi Joe:

Firstly NEVER EVER use ANY head cleaning tape (head scourers i like to call them).They are abrasive,or they would'nt sell them to to the said job over normal ones.The wet type,are worse the material can get wrapped around the capstan.I had to sort some ones out which did just that.ALWAYS use a good quality normal tape to clean heads.It will take longer but is a lot kinder and after to those ferrite chips.Is the picture coloured but very messy and bleeding to the right of white objects?If so it's probably the heads have been worn down b a lot of use, poor quality tapes, or overuse of the tape scourers (cleaning tapes).If it's picture 'noise' it could be dirty heads,damaged broken head chips or something electronic in the head amplifier or associated video board.Also poor capacitors in the PSU can affect certain associated areas if bad.The idlers and belts will also need renewing , if not done for many a year.A lot have not.You need the mechanicals perfect first before checking out, back tension and the like.Put a good quality tape in it and make sure it's not getting damaged first.If not let it forward search and see if this picture does'nt clear itself up.Keep us posted.

Joe,

Sanyo VTC-NX10 is a really good machine (and most Sanyo betas). It is worth repairing, but it seems that your local tech does not want to complicate himself too much. Normally, a new set of belts/idler, PSU checking, general and heads cleaning, and alignment (if needed) would bring your Sanyo to full specs.I specially like the NX10 because of its vivid colours and reliable operation.

Pd: a working, refurbished SL-HF950 may cost up to 300-350 eur on Spain. They seldom appear on eBay.

Hi JoeIn regards to your Sanyo NX10 bwing impossible to fix, i find that interesting.Sanyo's are one of the easiest and most pleasant VCR manufacturers to work on.Their beta's in particular.Most 'service guys ' opinions with vcr's (especially beta's these days) is I don't WANT to know so i'll fob you off.I've been on the end of that a few times myself.Hence why i now do what id do.

A pity you did'nt live a bit nearer,i would be more than happy to help you out.

Noel,

Yes, I read your comments about fixing the black loading gear. As you have correctly mentioned, I have never tried that kind or repair. Instead, I take a "healthy" unit from a scrap/donor video. On the bad side of things, betas are more difficult to get as time passes, so I should start thinking about repairing gears and broken teeth.

Is it possible to have a picture(s) of your labours regarding these fixes? It would help a lot. (I think you have my email from the past).

As always, thanks a lot in advance,

Gabriel

Hi all.

Re: Sony SL-C7UB

I have a couple of questions although I suspect one of them has been asked many times before but I couldn't find any way to run a search.

My first question is regarding replacing the "Toko" press-to-make switches on top of my C7 timer panel. Are there any known sources of replacements for these switches? I have 4 machines and every single one has seized up. Somebody has suggested using some thin plastic-friendly lubricant such as Peco "Power Lube" but I'm not sure whether this will work or not. (I have some on order.) Some of the buttons are seized solid but one or two will "lift up" but have no springiness to them.

My second question is regarding the AG7 BetaStack. I was wondering whether there was supposed to be some kind of clip at the back of the unit as well as the one at the front. It works okay with only one clip but the whole unit lifts up at the back as it pushes down the cassette lift. There are a couple of little metal pieces which look like they might slide into something but they could of course just be supports.

Many thanks for the help everyone.

Kind regards.

From Mike.http://www.oldtechnology.net

Gabriel,

Sorry I should have read your last email more carefully. I see now you have not tried it.The main issue is to get use a fast drill with the right size to match what you are using to pin the gear. Martin has asked me to do a few photos to assist explanation of how this repair is performed.

Yes the black loading gears breaking and spinning on shafts are the main issue causing failure these days. I hope you have managed to repair them using my method shown at http://www.palsite.com/100tech.html

Noel,

I go along with your statements regarding F30 & F60 machines. They are prone to break the loading mechanism gear (the one with the lever). I haven't ever attempted to repair one of those gears, but I will remember your method just in case. Also, the small black threading gear is really a cause of malfunction in C20 /30 F30 /60 machines, not to mention the issue related to the tape end detector spring... Sony and their fantastic "plastic designs", getting worse with age.

Sometimes I prefer Sanyos: getting every belt/rubber changed, keep an eye on certain caps and that's all. Bombproof design.

Gabriel,

I have seen the black and white issue on SLHF950s and it came down to chroma adjustments getting out of whack. The main issues I get with F30 and 60s are the load mechanism teeth breaking (the last tooth in fact) which can be repaired by heat melting the tooth plastic to hold it back in place then drilling holes in it and the second last tooth and bending a pin into a square cutting it and inserting it to hold the teeth together like a bridge in dentistry.

The servo control boards are no fun either.

Gabriel,

The F30s and F60s are prone to damage in the centre of the base video board around the centre plastic support. if they are dropped the bakelite board cracks and tracks are broken. If you bridge over the breaks using teflon coated wire wrap wire then you can fix them. just soldering over the crack is not a long term solution.

Dear Betaphiles,

Do you know a solution for F30s and F60s showing only black and white image? What I usually do is just swapping the entire "video" board, containing the Chroma Process. I have 3-4 scrap boards with this isuue so I would like to fix them.

Any suggestion?Thanks in advance,

Paolo,

The C9 audio output Ch1/Ch2 output options can be selected by via a front panel switch.That is CHA to both outs, CHB to both outputs or normal out A/B position. This was used for multilingual broadcasts.

Check it to be sure the problem is not dirty contacts in the switch. If the switch seems to be working, it will indicate if the problem is output path related or source related (before the switch)

Ripples to the tape edge and dirty heads will affect playback performance but broken solder connections on the audio board are also a common problem on aging beta machines.
