I am in the process of renovating a Sanyo VTC5000, and need two missing buttons/keys - one for record and one for rewind. Anyone able to help please? Alternatively, would be willing to take a whole scrap machine, if it has these items.

I have probably a Betamax sickness :)

I had to buy sl hf 100.

Plays unfortunately only in black and white color.

What could it be? Typical errors for this type vcr?

Also noisy drum, helps disassemble and lubricate bearings?

Nowhere I have not found a service manual download ...

Please advise me, especially with the color in the image.

Thank you very very very much.

Bonjour. Le hall effect sensor de mon SL-HF950ES vient de claquer, j'ai vu trop tard la colle marron fondue qui l'enveloppait. Après nettoyage il a marché encore par moments mais maintenant cela semble fini. Je n'ai jamais démonté de moteur ni de tambour de tête. J'aurais besoin d'explications précises et dans l'ordre pour le remplacer. S'il faut dévisser le tambour je ne sais pas comment faire, je ne sais même pas comment enlever cette barre de plastique noir à côté de celle qui est en métal au dessus du tambour... je ne trouve pas de tuto sur Youtube. Par contre j'ai le "Service manual" en PDF. A l'aide ! Et merci encore.

I connected a video Sony SL-C40ES to a Philips LCD TV by a euro connector. Adjusted the tv to receive video images through the Video Signal Test and tune the frequency using the analog TV tuning. So far, so perfect, but when I want to play videos recorded above, no image is displayed on the tv. What I can do?.

Damned,

I always tighten up the head base mount screws fully because there is still some give in the springs and the purpose is to have the drum assembly seat itself as flush as possible but it allows for some give in the mass if the unit is dropped.

I also agree that it's best to avoid adjusting the three preset screws on the ACE assembly. They interact with both the audio and video so you have to observe both at the same time including right and left channel phase balance and frequency response which is why I developed my own test tapes with the audio range being swept 25 times a second in order to quickly check and restore the correct settings if necessary on the SLC9.

The HiFi tracks can help in alignments for those machine as well as tracking centre for HiFi and video can differ and you need to reach an alignment balance for that.

Nospam@gmail.com

I agree Kevin,

Fiddling with the ACE adjustments is sometimes "risky" on Beta machines (on VHS machines is generally easier). Unless someone has tweaked before, leaving the factory preset is always the best solution. When the CTL/audio is out of alignment, it is often due to the pinch roller.

Firmly tightening the three screws under the head assembly is enough to get good results.

Keep those three head drum securing screws as near to secure as possible.

I've removed many and always set them like that.

Also the tape path should not normally be adjusted,unless someones fiddled with it before and put the alignment out.

Damned,

When a problem of snow image arises, I try to attach a CRO to the RF out of the head preamp board. Looking at the pattern showed by the oscilloscope you might be able to guess (or at least having a clue) wether you have a problem of the tape entrance / exit side or worn heads so the issue can be spotted. Also check for the head switching pulses to be correct. As a rule of thumb, when replacing hall sensors, I screw back the three screws until the end, with common success.

I have also realized that you have an audio issue (that annoying buzzing sound so typical from the C9s). Usually there are a couple ICs involved on this problem (check the technical section, it is described).

Hope you can fix that lovely but complicated machine.

Found these two solutions which may or may not help.

1. Check capacitor C38 on the RV7 board for failure.

2. Check for dry joints around transistor Q701.

Could also be dirty or clogged heads.

It won't accept a tape as the loading arms are out. It's a safety thing.

Try moving the small switch just in front of the head drum.

It is a white rectangular box with a lever. If that is faulty it could be causing your current issues.

Most likely the black plastic loading gear has broken and is spinning on its drive shaft.

It performs the dual role of loading the cassette then windin the tape around the video head drum.

Look at pal site Betamax page select videos then SLHF100 from the list and the select technical and look at the bottom of the list for instructions on how to repair the gear.

Good luck

not black plastic that speaks to me, but I think the problem is not going out there.

I will try to explain as best as possible, because my English is bad, I speak Spanish.

when you turn it on and hit the stanby no tape, the tape compartment is up, but the charge rolls are as if there was a tape inside. the tape compartment right, I take it out and put my tape manually load and switches guncionan perfectly well.

when I return to give the stanby and I again turn is when all the lights play, winding, rewinding, rec, pause light. then starts to rotate the spindle and the spindle motor, but not the collection roller tape. the solenoid does not act above nor below. then I give stanbay to stop and if I leave one minute so when I come back to give the stanbya engines are stopped.

I think it is an electrical or electronic problem, a tension that is not or something.

Jose:

Also did you do the tracking pot ands servo check like I suggested?

What you do is put the vcr in the picture search modes both ways, and gently turn the tracking pot each way.The 'noise bars' should rise and fall (depending on which way you turn the control)in sync with the control.

They shouldn't stay still (when moving the control) or cycle on their own.

If this doesn't move them then it IS faulty.

Have seen this many times and now found a reliable way to repair these so you shouldn't have that happen again.

Do you know how to do this. It is quiet fiddly to do if you've never attempted this.

The head drum needs un securing and a bottom board unscrewing to gain access to this.

Plus you have to be careful of those oh so fragile heads.

That is a very common on the m30 and M40.

The internal metal parts come loose inside.

I have successfully repaired many and have six here now already sorted out.

The whole tracking part needs to be unsoldered from the front panel and the replacement one re soldered in.

I thought you'd just had this sorted out?

I have been doing more test and i think the control tracking is broken.

The Wheel of track control seens to be like it is broken or disabled.

I remember when i take off the front of the other m40 that a little plastic piece was broken.

Maybe is part of control tracking?

Finally i could not find the dissasembly manual of this VCR, i have workshop manual but only have schematic diagrams and other things so i cant see how to solve the problem.

i have also in some tapes like a noise in the picture, specially in the upside of the image and if i try to move the track button nothing happens.

Hi everyboby.

First I want to thank Gabriel for sending me Betamax spares for my SL-T50ME at a very reasonable price. And you made a parcel solid as a rock, Gabriel !

Thank you also Kevin for giving me confidence in unscrewing my 950 LS panel. I was afraid there was some kind of trick but all went OK (it didn't crack) except that the 4 first turns were overtightened as I never saw before ! After a close look all seems new and never touched before. I found this http://lavorivideo.altervista.org/blog-lavori-video/ripristino-peak-meter-sony-betamax-sl-hf100-ec.html . This Italian guy seems to think like you that the problem comes from the cms leds and not the ICs. I wish you are both right because the ICs really cannot be replaced and the whole little board is probably impossible to find. What makes me afraid that it might come from the ICs is the fact that some of the bottom green leds never light except for some milliseconds when I hit the stop button. (If they are dead why are they able to light briefly ?). Also, when playback is stopped the first bottom green led is always working as it should but when I hit play it goes off ! Anyway as it is the only solution to try I will order SMD leds 0603 and try replacing them.

I will first change the Play, stop, FF, RW and Still microcontacts, I've got spares. I will also replace the dead Rewind orange led, and there is no led for the stop button !

Regards.

Damned;

If you do the check like I stated that should highlight if it IS the hall effect sensor.

If you don't feel any resistance when trying to turn the top of the head disc ONLY when the play light is lit then it's not that.

The intermittent capstan could be linked to the non head drum turning.

Sony's are renound for failed transistors even IC's in their beta's.

Like I've stated before whilst the C9 is an impressive machine it's also plagued with faults after time.One of the drawbacks with being so complex.

Also if you look on the faults page for the C9 here there could be issues which are similar to yours.

Good luck...................Kevin

You have the vey common failed hall sensor to the drum motor.

When pressing PLAY with the play light lit try to turn the top of the head disc. Do you feel resistance when the play light is ON?

If you do the hall sensor has failed.

Oh and the load end switch will also cause no loading too. Forgot to mention that:)

I have many betamax tapes. many of them are originals, i have a lot of tapes of rallyes some of them in UK like RAC RALLYE, i dont think this original tapes was recorded in superbeta mode, but as you said, M-40 has better quality that HF950 in superbeta mode and i am sure that i havent any pro-x tape, so i think the M-40 can give me the best picture quality of this tapes.

Yes you can record in Superbeta on ordinary tapes, but even then I would say the better quality the better the results. Sony only made the PRO tapes. It was their 'baby' after all, and beta was considered by many defunct by then :)

As for cleaning the tapes.

The dust should only affect the beginning as the rest is compacted up.

Unless you have mould (which you can see normally by looking through the cassette window. It's like white powder.

I would suggest a unlacing Sanyo top loader in good mechanical order. Take off the top cover put it into FF and hold something suitable to lightly clean the tape as it passes forwards and even Rewind.

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

Frandid:

From what I remember, you have to undue two screws at the m=bottom of the skating mechanism front panel,with this out.Then you tilt this panel up.

Next there is either one or two screws you undo and that should let you take off that VU level panel ,it will also need unplugging from the connector lead too. The drive IC is on that panel under a black dome. Impossible to replace.

Why Sony had so much trouble with these I don't know, but they fail regularly on the HF100 and HF950.

I'm not sure what's going on with the screws on yours but undoing them shouldn't make the panel crack.

Unless someones been in there and overtightened them?

Hi Kevin Lambert and everybody. I really don't think it comes from the leds but I want to see how the vu-meter is build and if there are dedicated ICs close to it. Big problem is : I see that the main front pannel is easy to unscrew and also that the linear skate has to be opened and its own pannel has to be unscrewed first... BUT : The LS little front pannel seems impossible to unscrew ! I follow what is shown on the sl-hf950es service manual, first unscrew the 2 screws under the LS pannel, but when I make one turn CCW this pannel starts showing a little deformation and it will break if I make more than one turn !!! ?? What the hell is going on ???? Did anybody already unscrew the linear skate front pannel ?? How should it be done ?? I really cannot make more than one turn because it will break I am sure!!?? Also these 2 screws under the LS front pannel are much more tightened than those of the rest of the big front pannel, they don't loosen like the others. Even when one turn CCW is made they are still VERY tightened, I don't understand. May some SL-950ES specialist help me please ? Regards.

thanks Mr Lambert.

As i understand superbeta pro mode is only in superbeta pro x tapes. I only know the pro x tapes of Sony.

Can you record in superbeta, non pro mode, in a standard tape?

it is only a curiosity

And other thing, is posible to clean the tapes?, not the heads, the tapes.

I have the tapes in very good conditions but 30 years old tapes have a Little dust.

Is posible to buy some machine to clean the tapes?

I remember in vhs somo of these machines, i havent one but i know that they exist.

I have seen these in operation and I do say the Sanyo M40 's picture is more detailed then the Sony 950 even in Superbeta mode. In Superbeta pro mode ,where you need the special formulation tapes, it's is impressive.

The 950 does not have any S video just the normal analogue connections ,but does have a scart socket .The ONLY PAL beta too have this 'feature'.

Mr Lambert, i believe in last post you said that m40 has better video quality than sony sl-hf 950 is that correct?

The sony has s-video output or only compound output like other betamax?

Frandid:

Congrats on the 950 purchase.

What you have stated is common to that vcr.

The failure of various LED segments to the VU level meter in particular.

The non LED illumination behind the main transport buttons is not however.

As for that plastic guide.Not that I'm aware of.

The LED meter board will have to be replaced or have some new LED's inserted. I'm sure someone once achieved that.

AS for the non functioning buttons try a tiny squirt of isopropyl alcohol to the switch. I had an M40 with that issue to quite a few buttons .It cured it. It's to do with where they are stored.

The random LED level response could also be the switches too.

The Sanyo M40 's picture quality is sharper than the 950 in Superbeta mode but Superbeta PRO is outstanding.

The reason the C9 is faster in the fast wind modes is because each spool is directly motor driven.

Hello. After my Sony SL-C9 F and my SL-T50ME I have just received a SL-HF950 ES ! It looks as good as the 2 others. It is in quite good working condition but has a few issues. First I tested playback and recording, the heads seem OK, no picture problem and no problem on the hi-fi sound. (Good news because I know that a new rotating disc for the 950 is worth more than twice the price I paid for the VCR !). So now these are the issues I am discovering, I hope they are minor and can be easily repaired ! First I'd like to know if it is normal that guide number 9 (last, after pinch roller, on right)is made of black plastic instead of metal as in the T50 and C9. This black plastic guide is partially worn. However there is no tape transport problem. (I could substitute a C9 metal guide if they are compatible, I have one left). Other things I notice : the rewind and stop buttons don't light. Are there lamps as in the T-50 or leds behind the buttons ? Also many leds of the sound indicator do not work, (mainly the lower vu-meter but also 1 or 2 from the upper one). As sometimes those of the lower vu-meter suddenly rapidly light when they shouldn't (no sound) I suspect the ICs operating them. Where are located the ICs operating the vu-meters ?? What are their reference, on which board are they ? Last thing I noticed until now, the rewind, f-forward and pause buttons are very hard to operate, I think the micro contacts are worn, are they the same as those of the C9, if yes they should be easily replaceable. I am continuing the test, then I will open the machine, I hope not to find more serious issues ! Surprisingly RMT 223 remote operates as if it was new. I have done some comparisons, if of course the SL-HF950ES is the best recorder, the best SECAM player is the SL-C9, the SL-T50ME and the SL-HF 950 come just after. All have a slightly different picture, but all 3 are better players than the SL-C6 F which recorded most of my tapes in the 80's . The C9 has an unbelievable dropout compensation system, and a brighter picture with more contrast. Also the C9 rewinds a tape much more rapidly than the 2 others ! Regards.

Thanks, i need only to re-aligned for this motive; this is completely gum up from old grease.

I need to overhaul, the FL and rebuilt this, but without a correct guide alignment is

difficult to rebuilt the FL.

I have buy the Service Manual, of the V-9600 but is a incomplete manual for me;

- Is Missing the electric alignment

- Is Missing the mechanical alignment

- Is Missing the printing layout board

Thanks again.

Joe:

There is..........

If you turn over the tape and look to left hand side an inch and a quarter down, you will see a small rectangular hole with a piece of moulded plastic covering this hole.

If you get something small and sturdy and push in this piece it will prevent you recording on it. As a switch inside the vcr needs this to be there to hold said switch down to record.

You can always put a small piece of strong tape over this if you change your mind later.

Hello, Is there a "write-protect" tab (or mechanism) on a Betamax tape to prevent accidental taping overtop previously recorded video? All other types of tapes (VHS, 8mm, Mini-DV, etc) have a method to prevent accidental recording. I do not see anything on a Betamax tape that would prevent me from taping over existing video. Thanks!

I have been doing a little research but the service manual for that model is not available for free (there is a web page which charges 7.99 US for it). I am not sure if you have a broken front loading carriage or you need replacing that assembly. Just let me know, I recall having spares for that Toshiba beta.

Frandid/Hellwyn:

The reason for this too is sadly with Sony,very early Sanyo ,Toshiba and NEC Beta's is the always laced up does exerbate the tape wear and obvious oxide shedding (those tiny magnetic particles) where there is high friction.

The Sony's will cause no picture output ,like you state, if the control track head get's blocked.

The Sanyo's do not.

Also some like the idea of Q tips for cleaning.I personally don't as that cotton is liable to come off anywhere.

There are special made cleaning stocks available from CPC and similar outlets specifically designed for cleaning tape mechanisms. They are blue plastic flat sticks with a angled head with a yellow soft material wrapped over this,which you use the alcohol on.

Also isopropyl alcohol is fine for cleaning the pinch rollers if used on a cloth.NOT to soak the roller in.It removes the accumulated tape debris(usually visible with a high glossy surface) very nicely.

Hellwyn did you also clean the A-C-E stationary head ? On the stationary ACE block you will find the fixed audio head, the audio erase head and the signal control head. If the control head (same head as the audio but one is on top edge and the other on bottom edge) is dirty the video signal can completely disappear. It happened to me recently on with my SL-C9 F and my SL-T50ME. I played tapes untouched for more than 30 years and some are losing oxyde more than others, it can be seen as little black dots everywhere on the tape path. I tried cleaning carefully the video heads it did not improve anything, then I cleaned the ace head and the picture came back. The fixed ACE head is not fragile so you can use a q-tip soaked in isopropyl alcohol. Do not use alcohol on the pinch roller and do not use a q-tip on the rotating heads unless you perfectly know what you are doing.

Joe - another way would be 3 x phono to phono, with a BNC adaptor at one end, and a Scart adaptor at the other (if your TV has Scart input). If you go this route get a scart adaptor with an In/Out toggle switch on it, and set it to In when connecting up.

You can get all this easily at electronics places like Maplins, or eBay/Amazon is awash with them. You can get them for under a fiver online, but I find you do get what you pay for.

Joe - what analogue inputs does your TV have? Hopefully either 3 phonos (usualy coloured Yellow/White/Red) or a Scart?

Get either a 3 x phono to phono lead plus a BNC adaptor if you TV has phono inputs, or 3 x phono to Scart (plus a BNC adaptor still).

The BNC adaptor slides onto the yellow phono lead and that's what you connect to the VCR's video out.

Finally My Sanyo VTC-NX10 is back to life.

After many months, better said, after some years finally the VCR are in my house and it Works fine .New heads and new belts and pinch roller too.

i plug the betacord in a Toshiba 32xv505dg LCD and the picture quality is not bad for an old beta tapes. Obviusly the resolution is not the same as broadcasting tv or DVD or something like that but the picture quality is better than my LG VHS, i am not sure but i think betamax has more resolution than 333x576i that has the vhs.

I will try to calibrate the tv to get best results, i am sure i can make a Little better configuration to see the picture but at least i can see my old tapes.

Now i am waiting for the two M40, i am sure that the picture quality in this VCR will be better than i have in NX10 and also the hi-fi system will improve the quality.

Hellwyn.

They protrude very slightly from the slot around the head drum on a disc.You have two for picture and two for the hi-Fi each set being adjacent to each other.

You will need some isopropyl alcohol and a cleaning stick.Some say use office paper with the solution on it works just as good.

Soak the instrument or paper and then gently apply it to the right side of the drum,flat with the drum surface and then turn the disc with the top screw clockwise only so each head sweeps over this solution about twice each head.Do NOT move the cleaning stick or paper up and down but keep it dead still.If you do move it up and down you risk breaking the head made out of a ferrite chip material and the M40 ones are like hens teeth to get new.

So be real careful.

Also look around the tape path and you will see if anything has come off the tapes(mould) that are causing your issues.

Let us know how it goes and above all take your time and be VERY careful.

There are four heads on the M40 head disc.If you have never cleaned any before you have to be real careful.They are easily broken.

What I would do first is play a really good quality tape and let it play or even forward search to the end.It may just do enough to save you having to clean them manually.

Hi Kevin, I checked the tapes and no, thjere's no ceration or damage to them, and like I said it's happening even with tapes I know are good. I checked them again after playing a short section and still no damage to the part that got played through.

Do you think I could manually clean the suspected dirty parts you mentioned? Are they easy to get to?

Will I be able to see the dirt on them or could it just be a bit of dust?

Hellwyn:

Also light dirt contamination to one head or dirt on the tape path near the hear drum entry will also cause the picture to jump and jitter as it's interfering with the control track pulse recorded on the edge of the tape.

Hellwyn:

What you have there is dirt or contamination that is affecting the control pulse at the beginning of the head sweep.

No doubt from poor/damaged or worn tapes.

Look along the tape edge, is it creased, serrated?

This is also typical if the entry tape guide has been badly adjusted.

But I wouldn't touch that....!

Hi - I've been playing some admittedly ropey old tapes through my Sanyo VTC-M40, and now even good tapes have a very jittery picture.

Please see video: https://youtu.be/FiGqgge2FKM

Is it just dirty heads, or something worse? Usually with dirty heads I find the picture is snowy, and clears after a while, but this is very different. Almost like the picture cable is faulty (I tried a different cable and result is the same).
