You are correct, these Sanyo machines sold in huge numbers. I used to work at Television Parlour based in Fareham Hampshire. They used have 500 units delivered every Wednesday (delivery day) and would sell out by the weekend usually. They used to retail at £169 at the time. Before the VTC5000, VTC5150 they used to get 500 units of the VTC5300 etc & VTC9300 every week and sell out at £169 each.
Thanks for the helpful video! My mum picked up one of these 1982 VTC 5000-II units for free, along with the original manual and pause remote! It even came with a stack of Beta tapes (recordable and movies) and even the original L-250 tape bundled with the machine! It's in amazing cosmetic condition but has some quirks. Will be replacing the belts with the help of this video. Despite being nearly 40 years old, the belts were only lightly stretched. I'm so used to servicing dozens of VCRs that seeing the insides of a Beta machine for the first time in person was an amazing sight! As with the tape you used, these Beta tapes are also quite mouldy. I'd recommend opening it up to clean it off, as mould buildup on the heads wouldn't be ideal.
For anyone else taking one apart, that black strip that sits atop of the cassette cover at the start is also clipped in at the centre, and not just stuck on. You need to push something like a screwdriver on the underside of the cassette cover to unclip it, which it can then be pulled off.
You should certainly start by replacing the belts, there are only two. It may need a reel idler, which is a bit harder to source these days, I had a stock until last year but now have run out.
Just want to say thanks for your info on the torque fix for the VTC-5000 (Replacing D6 and R49) The player would stop part way though the tape as there was not enough torque on the take up spool. Your fix worked a treat ! Thanks, I'd have never worked that out for myself :-)
Glad to have helped!
Memories! My first VCR was the Sanyo VTC5000, that I got cheap from an ex-rental clearance dealer in around 1989 when I was doing my BTEC in electronics. I enjoyed tinkering with that as well as a Sony SL-C6UB that a relative gave me, that machine was a tank, the solenoids made very satisfying clunk sounds. Unfortunately they are long gone, I eventually transitioned to VHS, as much as I appreciated the better qualities of Betamax.
Love watching these videos over and over Colin. Amazing thank you!
Great video - totally agree with your comments on the engineering (as I discussed in my own video last year) not only WELL built but very cleverly engineered down to cost without making any part of it rubbish. We could learn a lot from that approach today.
Would be great to find out the fault in that second machine. Maybe dry joints as you mentioned earlier, or cap faults on the syscon board? I had to totally recap the power supply and the servo board on mine to get it to work.
I may have another go with the second machine, and I've actually found a third VTC5150 in my store room. But this video was quite long enough already! You're right, it was a clever design. They eliminated all solenoids to keep down cost and weight. I once modified one for cable remote control.
I own two SANYO VTC 5000s One with original box and manual and there both in excellent condition, And there great to work with, Excellent video as usual great fan of yours love your channel I`ve been watching for quite some time now.
I have a couple more of these machines to work on when I get a moment, so we may get to see some more fault-finding. Sanyo really designed these machines well. Lacing is a bit noisy but otherwise the mechanism is superb.
@@video99couk Yes noise is quite normal for these machines i`ve fixed loads of these machines and in most cases it`s the belt and idler issue these days turn the rubber tire inside out the rubber is still fresh underneath
I Already had a Sanyo M20 (Front loader). I Bought it a probably 15 years ago at a garage sale. Sort of worked, but not well. Three weeks ago I bought a Sanyo 5005 (Similar to the 5000) at an Auction for $10. A bargain as these things just NEVER come up anywhere in New Zealand. Even on New Zealand's main online auction site 'Trademe', they are never seen. After watching this video I purchased two belt kits. Both specifically for each unit (2 different kits). $20 per kit from a place called Star Components in N.S.W. Australia. This is about $22 New Zealand Dollars. I did the belts on both units and they now both work well. Thanks heaps.
Thanks so much for this comprehensive video. I'm just trying to resurrect my pair of 5000s. I now have a good idea how to fix the problems I have, which you've covered. One works well mechanically but has no picture, the other has a reasonable picture but chews up tapes when unlacing.
Hi, Colin. I have two Sanyo betacords. The VTC 5010-II who only plays perfect without the lid and the VTC 5300PB who plays perfect only when its warmed up (otherwise stops / shuts off). What could it be and where could i find a repair instruction ?
Kudos from The Netherlands.
These are going to require proper repair by someone who is familiar with electronics. The VTC5010-II is probably the easier one to resolve. The VTC5300 probably has bad capacitors somewhere and that's going to take some time to resolve. It's not possible to diagnose by remote control, someone really needs to work on them properly.
Been fighting with a VTC 5300P for some time now which simply refuses to transport the tape. For some reason the motor doesn't want to push the gear in place to run the takeup spool in simple play mode - it seemingly doesn't transport the tape when unlacing as well, making exactly the mess you mentioned (without a tape the spool does rotate there). Lacing works perfectly well after changing the belts but that's pretty much about it. It's quite frustrating. Unfortunately the 5000 and 5300 look almost the same inside but they're quite different about that. Wish I could get it to run without the carriage for debugging, but it simply won't do even when pessing all kinds of switches that theoretically connect while pusing carriage it into place.
Won't give up on it, but at the moment I don't have a clue where to start. But your video was still a big motivation to keep on going, thanks!
Yes the 5300/5400 have an older and more complicated mechanism. It's been some years since I worked on one. Keep trying with fooling it into thinking there's a tape in there so you can see what's happening.
@@video99couk Finally managed to get it running again!
Turned out the last big problem was a stuck idler (or whatever it is called in the 5300). After some cleaning and oiling everything's working fine now.
Unfortunately now the screen is rather noisy and a bit shaky, even loses color at times, where it wasn't before I took care of the sluggish mechanics. Very scared that I've messed up the head (or even alignment) somehow. Tried cleaning it with the help of the PALsite guide, but didn't do anything. Noticed that the picture problems (especially the color related ones) are getting better after fast forwarding, rewinding or simply stopping it for a second and then pressing play again. Maybe the tape transport is slighty too slow and results in this - but to be honest I don't know if that makes even sense technically. I'd hate to give up on it after working so long on it but at this point I'm really out of clues.
Hi, do you know what maybe causing a buzzing sound on my VTC500 on playing of the tapes?. I've heard suggestions it could be due to the bad tape (something to do with the HiFi, though there is no HiFi on the tapes or the machine), or maybe the connection I'm using (I'm using the aerial cable connected to an old 14" TV at the moment to my computer), or could be the tracking or a capacitor problem, but I don't think it's the tracking, not sure about the machine itself. I would hope it's just the tapes and not the machine.
Brilliant video thanks. I do find it a lot easier to remove the 3 screws on the right and the circlip on the left and remove the tape carriage before working on the idler. Found it impossible to reassemble with the tape carriage in the way 😊
Maybe I have small fingers! I almost never remove the carriage to work on these.
Thank you very much for all the time you are spending for this machines and for the really very good videos you are publishing here.
I have a strange problem with my VTC-5000 unit. Neither on the video nor on the RF output i am getting a colored picture. It is only black and white. If i am touching the adjustable resistor for the AFC (VR17) on the VD-1 board with a screw driver without adjusting it , the color is there. After putting it away the color is gone again. I replaced all the capacitors mentioned from you and the palsite but without any access. Do you have an idea, what could be the reason for?
Probably a dry joint, I've had exactly that fault in the past due to a dry joint on the bottom PCB. You should examine it closely with a magnifier, and take your time.
Thank you very much for your fast feedback. Actually i did this before and didn't see dry or week solder points. But i will take a look again.
Could it be also related to a bad cap or adjustable resistor maybe on the servo board? Especially VR4001 to VR4004?
Finally i fixed it - with voodoo.
Just soldered an isolated wire to one of the legs of this variable resistor and put it in a safe way on the plastic housing. I still cannot believe it. Never repaired anything of my electronics by this way. It's just magic.
Eugene Trundle would be impressed.
Great video! I have a 5000 and a 5550 (Which you also seem to have at the end of this video). I also have a 5350 which is the PAL+SECAM version of the 5300. The mechanism in these earlier models is very complex indeed. Out of curiosity, where did you find the 5550? It's kind of a rare machine but it was sold here in Greece because we used SECAM back then.
I've had the 5550 for quite a few years, I think it was an eBay find from the days that these things were worth very little. Yes it is a rare one, and I've found that this machine is sometimes capable of much better playback on very worn tapes than any other machine I have (and I have a lot of Betas!). I suspect the filter design in the RF circuits is different to the PAL machines and somehow this gives it the edge on bad tapes. The 5300, 5400 etc. are much heavier and a the mechanism has a lot more parts to wear out.
@@video99couk I compared the luma/chroma (VD-1) board of my 5000 with my 5550 and the 5550 uses Sony ICs all over the place so that explains the little difference in the picture quality. My 5350 blew its power supply recently. Do you have any spare boards from scrapped 5300s? I took a look on the schematics of the 5300 and the PSU board is identical with the 5350. I also need belts and idlers for my 5000 and 5550. Let me know if you have enough of them left in stock. I also have a very rare VTC 9455 which is a multi system machine, similar to the SL-T7ME feature-wise.
Thanks
@@crashbandicoot4everr I don't think I have any 5300/5400 machines, scrap or otherwise. Interesting that the 5550 has a Sony colour decoder system, like the VTC-M40 has all Sony audio chips. I have just a few belts and idlers left for the 5000/5150/5550, send me an email (look up email address from video99.co.uk).
I've recently got hold of a Sanyo VTC5150. Plays fine, except for one thing - there absolutely no sound. I've tried different phono cables, different tv, through an amp, but there's not a peep. No obvious signs of corrosion.
Any suggestions where to start looking first?
Thanks soooooo much for this video! I'm using it to restore an old VTC5000. Thank You!
I am working on my Sanyo VTC 5000 - which I bought new in the 1980's. I got a Desoldering Machine ZD-915 - excellent as I had to replace that Voltage Regulator 'chip' and had to repair the 10-core ribbon cable. I am still having voltage problems, so I am replacing the Zener Diodes in the Power Supply.
Hi, I have two identical Sony VHS recorders, one that suddenly stopped working after I put a tape in and started to rewind it, and when I came back a few second later the machine was dead, no power. I tried the fuse but still nothing. Very strange considering I have never had this happen on any Beta or VHS recorder I have owned. I heard that it could've been due to a capacitor. The other VHS recorder I have powers up but it will chew tapes up when loaded. Is there anyway of taking the parts from one machine to another?.
I bought a VTC 5150 last year after seeing in your video that it’s a better machine than the VTC 5000 as it doesn’t have that bug as carried over from previous machines. I recently bought another Betacord, this time it’s one that I’d never heard of. Murphy MVR 7007R it’s a good clean machine that in time will need it’s belts changing as it’s running a little slow. It has colour pause, rewind and fast forward search.
Some VTC5150 machines still have the bug, they must have fixed the firmware part the way through production. I've not seen that Murphy one but it looks like it may be related to the VTC5300/5400 which is an earlier model. Some Sanyo model numbers ran backwards.
Hello. Love your videos. I have a vtc 5000 that has sound on playback but static for the picture but when picture searching either forward or backwards has a picture. Would you happen to have any ideas what could be wrong? Thanks Chris
All I do to clean the heads is use a piece of paper and rotate the head around, and after a few attempts the video has cleared up. I haven't done this with a Betacord just a VHS recorder. I've heard lots of people say that head cleaning tapes aren't recommended, better to manually clean to heads.
I do both manual and head cleaner tapes, depending on the format and on the circumstances. Manual cleaning always carries a small risk.
Very beautiful video i just missed those days where sony sanyo akai toshiba Hitachi sharp pioneer sansui National Panasonic bNEC JVC
Yes, that was the bulk of the brand names in video at the time. I remember the first Amstrad branded video and was amazed at the quality, I suspect that Panasonic had built much of it.
Having just repaired one of these (with the help of Palsite) with various faults, if anybody is struggling with unstable output on the video output terminal I changed C108 on the bottom board (it's located on the edge of the board, 4.7uF 16v) not *C 1080* as listed on Palsite as that number didn't correlate to anything, this made a massive improvement.
I had a very poor and unstable mono image, annoyingly I then twiddled some pots to try and cure it, so the whole thing needed realligning afterwards,
Don't then do what I did and short out the regulator IC about ten seconds after getting it to playback better than it did new...
Thank you for your guide on replacing the 2 belts. I have successfully replaced the belts, the old ones were stiff so definitely needed replacing. The cassette now plays fine, also rewinding etc. The only issue I have now is sometimes the tape doesn’t fully unlace, I’ve cleaned the rollers with IPA and it OK but I’m still concerned it’s going to mangle my tapes. One thing I noticed was, when you stop the tape and it doesn’t unlace fully, if I rewind or forward the tape is unlaces and I am safe to remove the cassette.
There's a modification for this, see my web page:
www.colin99.co.uk/extras/reelidler/how_to_service_a_sanyo_beta.htm
I still have some of the component kits (zener diode and fusible resistor) if required.
Where do I get a Solder Removing Grinder you are using at 40:23? What is its name? Much prefer this method of removing soldered in components!
Hi,
Do you know what type of spring it is that fits around the pinch roller assembly where it attaches to the loading ring? I put it back after replacing the pinch roller, played a tape then as the ring span round the spring spring off into the stratosphere and now I can’t find it anywhere!
Cheers! 🙂
Thank you so much for making this video. Just scored a Sanyo 6400 here in the States and want to change the belts out. Not seeing specifically any for the 6400. Is there a different Sanyo model or any model otherwise who's belt kit will fit? Thanks in advance and thanks again for this video. It's given me a lot of confidence I can do this.
The reel belt and loading belt are the same on nearly all Sanyo models. The front loading belt does vary between two sizes.
Commenting on this video again because I found something intereseting regarding the syscon bug. So, about a year ago or so I bought a service manual for the VTC 5550, and it says the following:
"If the take-up reel base rotation sensor detects that the reel base has stopped during any of the PLAY, REC, F-SEARCH or R-SEARCH modes, the capstan motor, the reel motor and the video head will stop. *If the sensor detects that the reel base has stopped during any of the F FWD, REW, or UNLOADING modes, the reel motor will stop, and the loading motor will rotate in the clockwise direction. The loading ring will then rotate in the counter clockwise direction and, once loading is completed, the VCR will enter the STOP mode.*
So, did Sanyo designed these machines to behave like this on purpose, or was it really a bug in the code that they didn't bother to change until a couple of years later? It doesn't indeed make any sense to lace the tape when the take-up spool won't rotate!
PS: I put the important part in bold. It's not in bold on the manual.
It just doesn't seem logical to lace up in the condition of reel drive failure. It's the last thing you would want to do, because now you have tape out that you can't retract. I reckon it's a bug.
@@video99couk Do you have any idea how they programmed these syscon chips? What language they used, what machine etc?
@@crashbandicoot4everrThey’d use TTL (Transistor-Transistor Logic) I’d imagine. So they likely used OR gates, NAND gates and all that boring stuff.
Forgot to mention, but the other VCR I have, which is a Sony SLV model when it stopped working had the tape inside which I have been unable to pull out. Is there a way of removing the tape without power?. I've tried pulling the cassette up and trying to wind the tape back in, but there's way of doing this.
I've got a video coming out in a week or two showing eject from a Sony camcorder with no power. Some video recorders can be treated in the same way, but it depends on deck layout. Basically it meant putting a small power supply onto the loading motor (and eject motor too, in the case of many video recorders).
Great video on the beta machine fixes!
I have a Betamax Sony SL-F30 machine. Recently started with issue that once pressing play only plays for 2 sec and the stops. I opened up the machine and can see the tape coiling. What could be the problem? The idler? Thanks for any advice.
Yes the idler "pendulum" as Sony calls it can get stuck on the deck and not swing properly. Sometimes it's possible to add a washer to give it the required clearance to solve that.
Thank you so much for the advice! What type of washer will do the trick? Where do they add it to the idler?
I tried playing my VTC5000 a few days ago in an attempt to get it working, and for a moment I actually managed to get the tape t rewind for a few seconds, but after all I got was a click sound and a humming as though the power is slowing down. I also tried to press the buttons down and pushing down on the tape loader in order to get the tape to move abit, but I noticed that the machine was starting to overheat and a slight smell of burning from the vents. No idea if I've knackered the machine up by this. If it's the power supply or PCB connection that is broke, how do I go about getting this repaired?. The days of video repair shops are long gone.
There are still repair shops. See: www.t-m-f.uk/forumdisplay.php?397-Find-a-Local-TV-Engineer-Here
Very good job. But I don't understand why you don't remove the tape drawer to have easy access and to work relax ?
Little fingers! I just don't need to, but for some people it would be helpful.
Hi just watched the full video......excellent!! Are you able to do a clean and belt change for a Wega Video35 ?
That machine looks very similar to the UK model Sony SL-C6. It's very old, not a machine type I've worked on for many years.
Hi Colin, thank you so much for showing us al the important servicepoints. I already replaced both belts of my 5010 mark 2 but i can't het any picture on my screens. There is sound but with some flutter that i can not fix. I can send you a picture of the screen when i play the videotape. Best regards Robin.
Oh god, I had one of these. Had to figure out how to get to the belt on my own back then haha
I've spoken to different people who work on these machines about the problem I have with my 5000, and they seem to think there's a problem with the loading belt. I took the metal cover off that is above the loading belt and heads. The head drum spins when you press a button, but since tape doesn't come out of the cassette and lace around the heads I'm guessing something is jammed. All idlers and rubber belts seem OK, so I don't know what the problem could be. I emailed one person with a few photos but he never replied back.
If the loading motor (back right of deck) is spinning but the deck isn't lacing up, then the loading belt is much the most likely cause. It's a little fiddly to get to but can be done from the top without further dismantling.
36:18 - I have a 5150 that only has a torque issue on playback/record/pause, not lacing/unlacing, FF or RW.
Brilliant as ever Sir, just got one of these that I picked up for a drink working again! Didn't have an idler assembly but cheated and turned the idler tyre inside out as a semi-temporary fix just for testing. Picture quality is a lot better than I expected for a 'cheap' top-loader. Only slight issue I have with this one is that when the tape is stopped it doesn't lace back in to the cassette, any suggestions? I can rewind for a second which spools it back in but otherwise, it leaves about a foot of tape hanging out the cassette when stopped?
Torque mod kit is available for this unlace problem. See my web site. www.colin99.co.uk/extras/reelidler/how_to_service_a_sanyo_beta.htm
@@video99couk Ah cheers Colin, funnily enough _ shouldn't have jumped ahead in the video, I might have skipped a stage! I've gone through again and cleaned everything (including those tape guide posts) and it's perfect now! Still watching the video, shouldn't have watched the first fifteen minutes and thought I'd cracked it!
Whilst I've got your attention (!) - I have a Sony SLV-715 which needed a tape guide alignment (was a _Frankenstien's Monster_ machine made out of bits) all good except when I get perfect picture on the scope the sound is strongly distorted and very loud on the R-Channel (HiFi tape), is this probably a knack'd set of HiFi heads? Only does it when the picture is perfect, which is annoying as I get a choice of perfect picture with awful HiFi audio OR a slightly wonky picture and linear audio!
Do you still sell the ldler kits and the resistor and diode for the take up torque?
I have a few belt kits and resistor / diode components, but I sold my last idler a few weeks ago.
How do i go about buying a belt and torque kit?
I bought a Sanyo Betacord 4500 on Ebay from a seller who said it was working. Well, I received it today and it powers on, but I can't get it to load a tape into the transport. It makes noises, but will not take it in. Is this a difficult repair?
I have a Betacord 4400 that looks almost identical to this. The only issue is getting it to lace, which it will do only if I move the loading motor drive belt by hand forward then back a little before pressing play. Will replacing the zener diode help resolve this or could it be something else? Also, what wattage is the diode? Thank you for making this video!
The loading motor is not related to the diode. Is the motor spinning and belt slipping? If so, just replace the belt. If the motor is stalling, that's unusual, it could be the lacing mechanism needs lubricating or it could be a fault with the motor driver electronics or power supply.
@@video99couk The belt was slipping, I can't believe I didn't notice. I have new belts on the way. Thank you for the fast reply!
It appears that these particular Sanyo Betacord's are quite hard to get hold of that are in full working order and are not spares/repairs for upwards of 40 quid. When I bought my 5000 2 years ago there were quite a few that were listed as in good working order, but not so much now. I wouldn't have thought there was a demand for these recorders compared to VHS, and even VHS most people think you're old school when you mention them. Saying that, my original Betamax was a VTC9000 (or 9300) which weighed a ton (19kgs doesn't seem that heavy but it was like carrying a bag of cement in your arms lol), I had two, the original recorder which was all black and grey went to the tip years ago, and the second was an all grey colour but identical in every way. As the recorder was full of dust and needed alot of repair work I decided to give it away to anyone who wanted it, and I must've got about 10 replies in the space of an hour after advertising it on facebook, so it must mean there is still some interest in these machines, or maybe because it was free. By the end of the day someone came to pick it up.
I wonder if the problem I have with my 5000 is that the tape belt has snapped rather than it being down to the power supply. When I try and press play, rewind, FF etc you hear a click sound and a "winding down" sound as if a fan is slowing down. The clock lights up but nothing happens when you select a number.
That VTC5000 sounds like it needs a new reel drive belt. They are easy enough to find just based on size, and it's not too hard to install either.
Why didn't you take the tape carriage out? It is easier to change them if it's away, well they say anyway. I want to find out where to purchase those belt/idler sets.
I prefer not to, my fingers easily fit around the cassette carriage. Belts you can order by size, but the idlers are now harder to find.
Great video i have just purchased this model cosmetically great but definitely needs work, please can you advise where i can purchase the idler and belts from please, 👍
Belts you can just order by their sizes, eBay search for cassette belts. The idler is harder to source but a few places still have them, including a supplier in Australia I'm told. I used to have some but sold out recently.
@@video99couk thank you for responding 👍👍
Hello, I’ve just cleaned a 5000, and was looking to adjust the drop out compensator. I can see the hole marked DOC, but how on earth do you adjust it? On mine it’s just a hole. Thanks
There's a small preset adjuster inside that can. You need a very small screwdriver to access it.
@@video99couk it must be tiny! Thank you!
When i'm cleaning the heads i just use writing papper soaked in rubbing alcohol and place it up against the head and turn it counter clockwise what do you think about this method also i love your videos i'm a hudge fan of the beta format
I've heard of that technique but not tried it yet. I may have to later though as head cleaner sticks are getting hard to source.
@@video99couk I use good (washing machine safe + and no cloud of particles when unfolding) paper handkerchiefs. I've never had a visible fuzz on the edge after the head, and I assume that non-visible dry dust flies away when the heads are turning quickly.
Hello again, your videos have inspired me to get out some of my old machines and do some work. Had an old VTC5000 which I though was only good for parting out, anyway found some new belts and idler rings. Replaced it all, cleaned inside and the picture was stunning, but there are some rolling drop outs, not loads. My question is about the drop out compensater. I tried to adjust it with a plastic tuning tool but it's a deep set screw and looks a bit worn, a metal head might work but there are solder connections near the hole and I don't want to short circuit anything, do you have any tips?
First, select pause. Do the dropouts continue to roll or do they stop with the tape? If they continue to roll, it's not dropouts but arcing in the reel motor. If they are dropouts then maybe power the machine off, adjust the DOC control slightly with the metal tool, try it then. I'm not sure which way to turn it so you will have to experiment a little.
@@video99couk Good stuff. Thanks for your help.
@@video99couk Hey, I didn't have the issue when pausing so I don't think it's the motor thing you mentioned. If seams like it's playing a bit fast esp when adjusting the tracking. I stupidly started messing with some of the other adjustable parts like sub trac and FWD. Any other ideas of what I could do?
@@SoulDamnFunky If it's playing fast there will be noise bars through the picture. Is that the case? If so, you have a fault which is going to take a bit more time, effort and knowledge to fix. I can't debug a servo problem remotely.
@@video99couk I'll keep at it. It's only an old mashine. All good practice
Off topic slightly, but anyone know why so many VCRs (VHS rather) for sale on ebay don't include the remote?. I've noticed alot of sellers don't seem to have the remote control for some reason, which is pointless when all you can do on the machine as far as buttons go are the rewind, fastforward, play and record, anything else like tracking (which is an essential thing when playing old tapes) - particularly if it's a more modern VCR, will be consigned only to the remote. Back in the 90s pre ebay a brand new replacement remote from somewhere like Curry's was about £50.
People just lose them. A £1 remote control from the pound shop will often fill in for many (but not all) of the missing features. I did a video about that a while ago. Most remotes within a brand will also work most functions of others of the same brand, though there are exceptions.
you wouldnt happen to have a service manual or manual for a 3900 would you? fixing mine up this video is super helpful
Followed your guidance and replaced belts. As per your bit at the end when I hit rewind it goes a few seconds then stops and laces. Pressing stop retracts tape and I can eject. Comment in suggests second idler wheel is bad. Looks like idlers are now scarce is there a way to fix this without a new idler?
You could try to source an idler tyre, based just on its dimensions. I'm also told that there is an Australian supplier who still has some idlers left.
Good afternoon, My Betacord Sanyo VTC 5000 is doing something wrong, the part of the video from the top is reproducing at the bottom of the screen and the part of the video from the bottom is reproducing at the top of the screen. Could you please tell me if this is something I can fix cleaning the head of the video as you do on your video?
Could you please tell me what liquid do you use? because a lot of people is telling me to use alcohol, but i'm not sure about that.
Thank you very much
Is it doing that for all tapes? It sounds like a massive tape path error. Cleaning won't help.
@@video99couk thank you for your answer. I'm sorry to bother you but I don't understand what is happening because It's been refurbished a month ago.
Answering your question: not all of them. I tried like ten tapes and it did it in six of them (all originals). I don't understand why.
Thank you for the video, helped me with my Sanyo Beta (VCR 4400). Can you give me any advice on one function I cant seem to get working. The rewind on goes for about 5seconds and shuts down and starts to auto play, but also binds up the tape. FF and play all work fine, but rewind, 5 sec and binds up the tape on auto play. Thank you again.
There is a Syscon bug in these in that they will lace up if REW/FF fails. So check that REW is actually rewinding the tape at a good speed first. If not, suspect idler, drive belt and reel motor in that order.
So my reel belt keeps breaking after about an hour of play. Everything plays beautifully up until then. I have used 99% iso alcohol to clean motor spindle and the plastic spindle but still breaks. Any suggestions?
I should add i have a front loader. Did this with and without a new tire. Im not sure if the reels need lubricated or cleaned or the pully or what? Its my first beta player.
I've never known reel belts keep snapping, other than with age. No lubrication required. Make sure that the reel idler's clutch is still able to slip, it needs to be able to do this.
Just working on mine, I noticed some aluminum oxidation on the polished surface of the drum. I don't know if that has the potential to damage the tape, but likely.
That can happen but rarely causes a serious issue. You can very gently go over the static parts of the drum with fine emery cloth, avoiding the head tips of course, to reduce the oxidation a bit. Don't overdo it.
How do I set back tension on my Sanyo Betamax m30 I don’t have a jig or anything how was this done on the sanyos ?
Picture is distorted and if I move the back tension arm picture is fine also the tracking petontiometer is not working and these are a bugger to replace what would be the best replacement option you think
Thanks in advance
Back tension rarely goes out on these machines. Bigger problem is that the tracking control isn't working. It's not likely to be the control itself, it means that the capstan servo is not locked. This may be due to a dirty audio/control head, or another fault in the capstan servo. A service manual is required and you need to know what you are doing.
Thanks for the video, with new belt my RW and FF are much better, my picture is fine but no colour, whereabouts or which pcb controls the colours, is it a crystal
The colour processing is mostly on the bottom PCB. I've had dry joints on colour processing on that panel in the past.
Colin. Great informative video thank you. Managed to replace all the belts. Plays but when I press stop the tape is not taken back into the cassette. Any ideas? When I simulate a tape being inserted by pressing down on the small detector on the left hand side I cannot see the tape drives being driven to take the tape back into the cassette. Trying to fix so I can digitise my friends home videos he has at home.
There's a modification for this problem, see my web page: www.colin99.co.uk/extras/reelidler/how_to_service_a_sanyo_beta.htm
@@video99couk Thanks I will give it a try. I would have thought with no tape installed there would have been some movement as there is really no torque at all for the motor to fight against.
I rang up a local TV/video repair place and mentioned that I have a Betacord VCR and he said that he only repairs VHS and that even 30 years ago noone wanted to repair them and the parts were hard to find. Surely there must be someone who is willing to repair them. As soon as you mention Betamax to these people they don't want to know. If there's a way a manually fixing the machine myself I would do it, but the repair videos are too technical for me.
Try some of these businesses:

Ive just purchased a Murphy which believe is a Sanyo. I have put a cassette in and it is stuck in the machine, the cassette didn't load. Is there a manual way of removing the cassette?
Remove the cassette lid (rubber strip hides two screws), then the cabinet top with three large screws at the back. The loading belt has possibly failed, that's at the back of the deck, replace that and it might work from there.
@@video99couk Thank you for replying. I have looked at the loading carriage on the Murphy and it appears to differ from the Sanyo models, doesn't appear to have an idler. I have since removed the cassette but after loading the tape again the heads just spin (before pressing play) and the again the tape fails to eject. Not sure if you are familiar with the Murphy? I have since found a Sanyo VTC 5000 which is in better condition, sadly Sanyo stops playing within a few seconds and the tape doesn't unlace properly resulting in a mangled tape! I am not having much luck!
Hola tengo un betamax sanyo ctv9100A el problema es que reproduce muy rapido,me podria ayudar por favor saludo desde chile
Hello, I have one that didn't work, I cleaned it and i had changenthe the belts and It works perfecly, then I stoped it and the tape of the video got blocked in the mechanism. I extract it very carefully and the next time I try to play it and it statarted to apear white and grey lines and the picture now is very bad. What could be the problem? Thanks.
I can't really diagnose it by remote control. It could be a tape path fault, clogged heads or some other problem. Start with a head cleaner if you have one.
What is the solution to the middle stained folding of the first video you showed?
Not quite sure what we're talking about, let me have a timestamp of the relevant part.
This is exactly the video I need to change the rear belt I have another beta max that smokes when I hit the play button so I’m thinking a gear maybe stuck but I’ll just use the non smoking Sanyo and change the belt
Did I hear you state they were assembled in Wales!! I think not, they were assembled in Lowestoft Suffolk my friend. I used to work there.
The reason Sanyo called them Betacord was because Sanyo developed a unsuccessful format called Videocord. They decided to call their Beta machines Betacord and the unlacing for FF and REW from the VTC5000 was another slight change to Sony's always laced design so made more sense.
I stand corrected. I was told back in the day that they were assembled in Wales. I am still trying to find a Videocord machine.
Great video Colin only issue now is i need some help.locating the part number for a new pinch roller or equivalent. are you able to.assist as I have the service manual for the VTC M40 and I've located belt kits and new idler assembly's I'm just missing the pinch roller part number.
if you could cast me a line I'd be most grateful bud
regards Darrell
Pinch roller failure is fairly unusual on these machines. I do have a single, brand new spare pinch roller for the VTC-M40, but I'm not quite sure where it is! The pinch roller changed somewhere between the VTC5000 and VTC-M series machines but I'm not sure if that change matters. I do know that the pinch roller on these is interchangeable with some VHS machines, so it shouldn't be too hard to find a generic video recorder pinch roller that will fit. What makes you believe the pinch roller has failed?
The VTC-M40 is one of the very few Sanyo machines that seems to get through video heads, both video and hifi audio heads can wear on this model. I think they may have been built by Sony.
@@video99couk Hi Colin i just wanted to keep.some spares more than anything to keep the old girl alive. The heads on my machine are very low mileage thankfully. watching your other videos I see your an avid sanyo betahifi follower 😉 whats the damage if heads go on these machines ?? can I source American equivalent model 7200 ? to help with spares ?
@@video99couk thanks for your assistance 👍 I may be calling you in the very near future
23:30 - Grundig did a similar thing on their first VHS decks (C-wrap mechanism), even that was (fairly) reliable!
Probably because Grundig also used a loading ring on V2000 decks, whereas early Philips V2000 used a horrendous M-wrap affair with wires and things. The loading of the Grundig 2x4 Super, my favourite V2000 machine, is fairly reliable. Alas the rest of the machine is less so, see my YT video on that model.
I've heard from another person that the fault my 5000 has maybe down to an STK chip or one of the transistors in the power supply has failed. Is this likely does anyone know?. Considering I cannot see any sign of the any of the belts broken this does seem a possibility. God knows how I go about repairing that. Strange that something like that would happen on such a reliable Betacord like the 5000; maybe a tape caused it as most of the tapes came from long term storage in the loft, probably had alot of static on them being (I've heard not a good place to store tapes).
STK regulator chip is something that fails on these from time to time. It's not particularly hard to source or change, just some basic soldering skills required.
I like your Channel verry much 👍
Charly deck = coffee grinder deck ;-)
Try to fit a new belt on that!
Btw, enjoyed your video, i still use 2 vtc models for video capture.
I remember fitting a refurb kit on a Philips Charly deck. It was fiddly but worked much better and ran for many years then. Well done for watching the video in so much detail that you actually picked up on that comment!
@@video99couk I watched it twice ;-)
12voltvids has some brilliant video on this subject too.
Thank you for the detailed information in the video.
Yes I subscribe to him, I wonder if he subscribes to me. I aim to be a mixture of channels such as 12voltvids, Techmoan, shango066 and Mr Carlson's Lab, though may never achieve quite such heights!

hi do you know any info on tascam DA38 DA88 DA98 making video's on the sony Sl-HF100 is a ace plan to i still have some as parts went over to betacam
as i been using blue betacam tapes in my sony Sl-HF100 now i have 8 sony Sl-HF100 sitting a rouund i love the later betacam sp dig units bob
I have Tascam DA-88 and DA98 machines, see ua-cam.com/video/jYCk4oWl5A4/v-deo.html&
You can also see my BetacamSP, DigiBeta and HDCAM decks on my various videos.
Next time I have a head drum failure on a Sony Beta, I'll do a repair video on that. The effect is that the head doesn't spin, but is held in one spot by the head motor, it's a very common fault on all the C20 - C40, F-20 a similar machines up to HF-100.
Also do see my series on PCM digital audio on Beta ua-cam.com/video/OPjOeir4iEQ/v-deo.html
Any tips on how to get it to eject a stuck tape. It ejected once, but never again. I have taken the top off the unit.
Probably the loading motor belt has fallen off. It's at the back right of the deck. Just replace that, it's not too difficult and can usually be accessed OK from the top. I cover this in my video.
Where do you buy these top idler kits now??
Not easy now, I sold out about a year ago. There may be a supplier in Australia who still stocks some Sanyo parts, search by their part numbers (available from my web site).
enjoying watching your series, currently trying to save family machine - vtc5400 - i have a striped screen playing through pc monitor - in play & ff mode the stripe screen appears to dissappear, any thoughs greatly accepted, cheers andy
The 5300 and 5400 are earlier models. I am less familiar with those, it's some years since I last worked on one. Perhaps upload a clip so I can see the effect.
I have a Sanyo 7250 that will glitch and only give me a b&w picture. If I tap lightly on the top of the player, it'll jostle something back in place, but this isn't a permanent fix, as if I change the tape or power the unit off, it'll revert back to b&w.
I've had dry joints on the bottom PCB in the colour circuitry before. I forget which is the colour processing chip part number, but just inspect closely for dry joints there. It's a simple repair.
@@video99couk I took the shell off and tapped the delay line and noticed that would change the picture back to color. Does this info help narrow the issue?
If it has propensity for dropouts then maybe the heads are knackered?
Heads are OK, tape was mouldy.
hi i used to know a man in bracknell who had 9 VTC5000 they have been used big time what you are doing i used to do this for him time to time
he used to get VTC5000 from the paper ad's i had one for some time till i got a sony 100 hi-fi
I have a few Sl-HF100 machines too. At some point I will do a video on how to replace the Hall Effect sensor in the head drum motor, because that's a common fault on a lot of the Sony models from the C20 onwards.
what causes blue flashes on screen when playing beta tapes
If the picture is fine in between the flashes then it's likely to be a timing incompatibility between your TV and the video recorder. Try another TV.
I can't take my eyes off that tape mould...
I get rather a lot of mouldy tapes of almost every format. In fact there will be a mention of that very subject in a video I'm working on now.
Can you do a video on how to use an oscilloscope to service a VCR?
That's a huge subject. We're talking about knowing how to read video recorder schematics and trace signals through the systems. Others have done videos showing how to use an oscilloscope to align video heads though, that's not quite so complex as fault finding the circuitry.
good information
i have sanyo vtc 5550 how to slow cassette not ejecting
What do you mean? Is there a stuck tape that won't eject?
20:22 That tape definitely look like it had mold on it
Yes it certainly did.
I though white streak on image means worn heads.
Yes, that can be a symptom of worn heads too. The effect from an arcing reel motor is a bit different because the white flashes jump around the screen even on pause, whereas with worn heads on pause, white flashes tend to stay fairly static.
I own a VTC 5300. It's a great machine, but unfortunately, it no longer works.
The VTC5300/5400 models came before the VTC5000/5150 etc. Sanyo's numbering system was strange. The 5300/5400 use an earlier mechanism which is heavier and has a lot more belts and pulleys. It's of the always-laced type, whereas later models unlaced during REW/FF. It's harder to find parts for the 5300/5400 machines and they are more involved to work on, but still possible.
Every time I see 'professionals' recommending cotton buds I cringe. As I've been sent a few to sort with heads ripped off or damaged by owners using these to clean the tape path. Many don't realise the heads are NOT the huge silver drum but located in the slot in the centre on a spinning disc. Another no, no is loosening the tape guides ,maybe in the hope to get it to play better, when it needs a good service. This action will make playback poor and mis tracked on both it's own recordings and others from other machines.
You will note of course that I only used cotton buds well away from the video head, and used proper head cleaner sticks on the head drum, for just that reason. On my Toshiba Beta video I also mention that tape guide adjustment is not something to be carried out on a whim, even when a machine seems to be playing tapes badly: In the Toshiba case it was due to a bad pinch roller.
