Hello, my c6 plays tapes correctly in video and audio, but when recording it records the video correctly, but the audio undulates in a constant out of tune, it only happens when playing something recorded from the video itself.Help please
Hey y'all new here!
So i have a sl-c9 where L361 in the PSU is very high pitched whining it is so anoying! I've spent 5 hours trying to find out why.
All caps in the PSU have been changed and before that it also had the same whine.
Is this common for L361 to whine? Other PSU from my second c9s also does that!
The whining is dependent on the load off the PSU, for example rewind and it pitches up
Are there any Infos in which value L361 has and which new Coil could be fitted and if it's even the Coil? I'm just out off ideas now.
Thx in advance!
Hi JoeyTech2000
Although I don't have a manual for this model, it almost certainly uses a switching power supply like the earlier T30 /T50ME multi system Betas. That being said, you may have a failed switching transistor or a failed MB3759/TL494CN PWM IC. If the mains fuse has blown up with burn marks then something is short-circuit in the primary side of the PSU.
Hello Everyone. I have a Sony Model Sl-800ME Multistandard.
The power is completely DEAD. Just tearing into it now. no sign of anything obvious, so far components all seem ok.
Just in the cursory check over phase of things right now.
Does anyone have a schematic or service manual on this one?
or perhaps a list of similar decks with same power supply? any help would be appreciated.
and just for you capacitor guys, none of them are bulging, or leaking on the board.
I will be going through them soon anyway.
To John Till,
I have not seen any commercial beta video tape cleaners but I have an original Sony tape winder/rewinder.
However here is a video from a guy who made his own unit. https://www.youtube.com/watch?v=KYPxLwgXbbE
Some ideas there on making a cleaning machine. See him demonstrating the cleaning process using his "do it yourself" home made cleaning machine but personally I would be using a mask whilst doing that.
I have previously tried to convert Sony SLC6 but tape drag was too high. Maybe an old Sanyo top loader would be a better starting point - stronger motors.

Good evening
I have some Betamax machines I want to use so I can begin digitising the numerous tapes I have. One of the machines is an old Sony SL C20 unit which is like to use. However, the sound is faulty
The alternative is a Toshiba unit which works fine but Id still like to get the C20 repaired if possible.
Does anyone know if there is a UK service centre I can send my C20 unit to so it can be refurbished/repaired?
I have a couple of Sanyo units which can be used by someone who needs spares - just let me know if its of use to anyone.
Best regards
Mark
Hi folks - I have recently acquired a Sony C5 -UB. It powers up, all appears to work - however, it won't rewind tapes. I found this: https://www.palsite.com/slc5tech.html - I'm assuming a 'rewind kit' is a set of replacement belts, which may have snapped over time. I'm going to roll up my sleeves and take a crack at fixing the old girl, but does anyone know where / how I can get hold of one of these rewind kits? Thanks all!
Does anyone know if a Betamax tape winder/cleaner has been made and where I can find one?
There are some available for VHS but I r yet to fine any for Betamax.

Hello Keith Wyatt
Have you checked that the tape counter is moving whilst a transport function is taking place? This machine has a hall-effect sensor on the tape counter that monitors tape movement. If the counter doesn't work (likely to a weak or broken belt), the microcontroller will think the take-up spool is not turning and will shut the machine down. To eject the tape in this condition, press the eject button, wait for the motor to stop, and then turn the power switch off and then back on. You may need to repeat this process for a couple of times until the tape is released.

Sanyo VPR 5800 new belts fitted.loads and plays the tape rew stops after a few seconds and eject not working .the motor dont spin in eject but loads ok.any help would be appreciated.thanks Keith
I finally managed to repair my SL-F1 betamax and would like to share it with you so hopefully it can help some people !
Symptoms : when pressing play button, it read the tape for 2s then stopped. Same on fast-forward & rewinding.
Repair attempt 1 : I replaced the hall effect sensors inside the drum head motor. It didn't help...
Repair attempt 2 : I replaced all the five 16v capacitors (thanks to https://youtu.be/q4GXNv3wQIM?si=GNi8G73QyE8JG7Gk&t=3978). It was definitely something needed but still not working after that.
Repair attempt 3 : I noticed that a leak of a 16v capacitor had damaged a track on the pcb. I soldered a bridge and it worked !
Conclusion : check the track conductance your leaked capacitor.

Hello, I am having an image problem on the SL-200ME device. I would be glad if you could help me show the image in black and white.
Best regards
Hi,
My Sony SL C30 video works in black and white.
What motherboard model YC41 should I change.
The recommendations for the YC25 panel do not fit my device.
Thanks.
Hi
I just purchased a Sony SL-T9ME. It requires a new drum head. I think the part # is DSR-19R A-6762-072-A however, this site says A-6762-075-A. I purchased one from a person in Jordan (I am in Canada) and sadly it didn't work. I can't find any other source for this head.
Any suggestions where I might source this part?
I am really hoping to get this machine up and running.
Many thanks in advance.

Good afternoon, I asked a question about a Sony sl-hf950 video, I repaired the loading motor of the cart, since the sheets were detached. Do you know if when you put the motor back in, the cart or skid has some positioning? And if someone has it, could someone tell me the process. Thanks in advance.
I have an NTSC SONY Betamax model SL-5400 without the owners manual can anyone take a time to scan and send me the Sony SL-5400 owners manual please? Any contribution will be appreciated Greeings fro Mexico
