Buenas tardes compaeros, he adquirido un video Sony Sl-C6 con muchos problemas, el carro la cinta entraba muy lenta no dndole tiempo a completar el proceso, lo he solucionado quitando el exceso de grasa seca, he cambiado correas he limpiado gomas adosadas a sus poleas, ya que de momento no he encontrado repuesto, no me funciona el test de seal, ahora funciona bien en play aunque no visualizo la imagen pero hace bien el rebobinado, pero curiosamente al darle a bobinado rpido hacia adelante lo hace hacia atrs.

A ver si alguno de ustedes me puede echar una mano,gracias.

We have a Toshiba Betamax that was sold to us as the 'top end of the range, far superior to VHS' (I agree). However, it has been sitting out in my garage for years waiting for someone to rescue it. If anyone is in the Hampshire area and would like it, I am happy to send it on its way to a new home where it will be resuscitated. Preferably collection - I don't fancy the postage charges!

HI,

My Sony SL-HF100AS is playing tapes great with hifi sound but when I power it up sometimes I can hear a crackling noise coming from the right channel and can see the VU meter moving too.

It comes and goes. with no tape inserted and during playback.

Any ideas where to check?

thanks

Mike

Betamax SL-C9UB. I have recently purchased this model from an auction, excited at the thought of playing old videos. But can anyone advise me where I can get a manual to help me set it up. And what leads I need to do this. Please any info in girltalk!!

Hi I recently acquired a Sony SL-C5 UB player. Everything works fine for the most part except when it comes to rewinding a tape. Most of the time it doesn't rewind the tape and it just stays still. However the player still makes the rewinding noise. The player does sometimes rewind the tapes but it's very slow when it does so. I was wondering if anyone can help me further with this matter as I don't want to chuck the player out as I have a feeling there's life still left in it. I don't know much about the inner workings of Betamax machines but I suspect the problem is a worn out belt. If anyone could tell me how to safely replace the belt or can put me in contact with someone who could do it for me that would be greatly appreciated. I think the machine would benefit from a clean as well.

Thanks

Hi Rich,

From personal experience I can wholeheartedly recommend Mr Betabyte for repair and servicing. He serviced one of my Beta vcrs in 2023 and did a great job. Just make sure you pack the vcr very well for posting as couriers/Royal Mail aren't too careful with these objects.

I am looking for a Betamax repair and servicing specialist for SL-F1 portables in the UK. I see Mr Betabyte and others have many youtube posts. Can anyone recommend a good contact? I had bad experiences in 80s of companies charging high prices and wrecking machines. Many thanks, any help gratefully appreciated.

Hi all.

I have two questions regarding a Sony SL-C5.

First question, is there a variable resistor anywhere in the audio record circuit that can be adjusted to bring the volume of the recorded audio up? When playing back pre recorded and recorded on other decks tapes back, the sound is crisp, clear and a good volume. The recordings made on this VCR are noticeably quieter with audible hiss. I've ruled out wear on the ACE head as this particular VCR came into my possession in barely used condition packed into its original box with all inners, bags, dust cover, boxed wired remote and accessories, and literally not a spec of dust inside. No visible wear on the upper drum also. I've changed the audio relay from the open top type (contacts were very tarnished) to a sealed unit thinking it might be that causing the audio trouble.

I've also marked and adjusted the audio head azimuth to try to cure the problem but the marked position is the best output.

Second question, is there a variable resistor on the video board to 'tune in' the E to E, as I've got very noticeable ghosting on text etc when it's connected via the video in jack. This ghosting isn't recorded onto tape.

I don't have a service manual for this so don't want to go poking about without knowing where I'm specifically looking for.

Any advice will be gratefully received.

Thanks

Rich

Dalton,

Regarding your loss of picture on an SLC30E (turning to black) that happens when the tracking pulse ceases to be detected. Alignment of the tape with the audio head changing is a likely cause. (Don't adjust alignment though because that is probably not the fault)

You should observe the tape on preview and review modes to see if the tape gets pulled up or down in during fast movement. Also inspect the tape for damage.

The ACE assembly which holds the audio/tracking head must be cleaned for a start. In your case I would check the capstan roller to ensure that it is gripping the tape evenly. From what you describe it seem like the tape is ridding up and you are losing contact with the control head. I have a video on you tube that shows how you can clean the capstan roller plus if you use that method you will quickly find out if one of the bearings has an issue because the roller will become unstable at high speed.

Dear Betamax PALsite community, my name is Franziska Aigner and I'm working on a film together with my friend and director Thuy-Han Nguyen Chi (German film prize for best experimental film 2023, her last film had its world premiere at New York Film Festival 2022). The film in part gravitates around a video camera from the 1990s, a Sony Trinicon HVC 4000P. The camera is currently not functional, even if we don't quite know what is wrong with it. As part of the film, we would like to collaborate with a camera technician who is familiar with this type of camera, and if possible, has furthermore worked with/on this camera in the 1990s, in order to first of all document the process of diagnosing and dissecting the camera and who would furthermore be willing to do so while being filmed.

We are currently planning to shoot the camera 'diagnosis' in the two last weeks of September 2025 in Troy/New York, which is why we are looking for someone based in the region.

If any of you would be interested in collaborating with us on this project, please reach out to [email protected]

Thanks a lot,

Franziska

Wanted: Any UK schools programmes from 1970s or 80s. Whatever tape format. Also interested in certain other types of 70s-80s TV material too, particularly kids TV programmes but other things too.

Hi, I have a Sony SL C30e here, which only shows a picture for a short time when playing, then goes black. pause or quickly move forward, go backwards and then I have a picture again. just don't play normally. anyone have any ideas. Greetings Rob

The SL-C9 is one of the most complex home VCRs ever made and finding a fully working one these days can be a challenge. The most common problems with this model are the two little plastic gears on the front loading mechanism and the DC-DC converter module that fails and causes the clock/counter display and the TV tuner to not work anymore (although the latter is mostly useless these days anyway). Other mechanical issues include the flip-up tape guide pins that often snap, and the upper drum that gets shiny and causes the tapes to stick to it during rewind, or cause excessive back-tension during playback/recording. This is a big problem with this particular model because it uses direct drive reel motors (no idlers, belts or pendulum gears) and the reel servo circuit will get confused or over-correct the situation if any tape drag occurs. If you hear a slapping or thumping sound during rewind then be sure to check the upper drum for wear. If the cassette loading gear(s) break then you will need to replace those before the loading motor draws excessive current and blows something up. The North American versions are the SL-2500 and 2700 (Beta hi-fi stereo version). All in all, it's a lovely machine when it works but a nightmare when it doesn't.

Betamax SL-HF300 (1984) not Sensing Inserted Tape

1. The machine cycles normally when powered-up.

2. The "tape inserted" sensor switch in the carriage opens and closes with tape insertion (checked continuity), however it is not triggering the loading motor.

3. The carriage is operating freely - I can drop and raise the tape via turning the appropriate gear by hand. The machine appears to sense the carriage is down, however the tape loading mechanism is not activated as again, the machine appears to not sense a tape being present.

Anxious to get this working as in 1986 I used the HiFi mode (audio only) to record a friends' 1983 release of the Beatles Original Master Recordings box set. Wish to download said recordings to archive them.

Thank you in advance for your time and consideration.

hi all - I'm wondering if anyone here is (or knows) an old school video repair engineer in Wales or the South West? While I can do basic belt changes etc., more complicated reopairs are beyond my ken, and I could really do with finding a retired video repair man who is happy to earn a few quid. Thanks.

After my parents both passed away, I dragged their old Sony SL-c9ub back to the United States in the hope of seeing if there were any old family movies we had not captured. To be honest, it never even crossed my mind that it might not be functional, but today I plugged it in, hooked up a cheap BNC to HDMI converter and lo and behold. Behold, the tape that was in it played and was a family movie!

In hindsight now and after looking at the tape mechanism and its complexity, and the plethora of capacitors all over the boards, I'm actually shocked it is in such Tip-Top shape.

I have a dozen or so tapes to go through and review. As I think about it, I realize if any rubber is in bad shape on the captains, further use may end in a jam. I've only played about 2 minutes worth, but confirmed that slow-mo shuttle is working just as I used to (I remember age 9 shuttling torville and Dean back and forth making it appear that he was kicking her in the head at the end of their Bolero routine).

Knowing that it is working 100%, do you have any guidance on what I can do to maintain it? I don't really want to unscrew anything.

Secondarily, once I'm done capturing, I will have no need for it beyond having a badass piece of technology. What do you think someone would pay for it? I have seen some posts of enthusiasts bemoaning their players slow demise...

To Clive Leyland What model and make of TV are you using and have you tuned the Test signal from your Sanyo so it's displaying on your TV if so when you play a tape the picture and sound should be displayed have you used the RF Converter which is normally channel 36 but it can be adjusted some TVs have a dedicated channel for viewing vhs or betamax tapes

I HAVE A SANYO VTC5000 THAT LOADS TAPES PLAYS AND DOES ALL THE TAPE FUNCTIONS. HOWEVER CAN GET A PICTURE ON A FLAT SCREEN LG TV. HAVE CONNECTED ANT OUT TO ANTENNA/CABLE IN ON TV, ALSO BNC VIDEO OUT ON VRC TO TV VIDEO/Y (GREEN AND YELLOW FHONO PLUG) AND AUDIO SIGNALS ON TV AND VRC RCA PLUGS. NO PICTURE AND NO SOUND

THE CABLES PHONO ARE OK AS WHEN CONNECTING A VHS PLAYER IT HAS A PICTURE
