The sound PCB is not separate it is part of a larger board. I do not suggest the cost as it may not fix the problem. Just replace the TV.

Dvd picture works, vcr picture does not work. Sound works from both. is this a problem with the machine or the set up?


Try a cleaning tape in the VCR. If the pictures both come ut of the same connector then the VCR may be in need of cleaning. Also can you see a picture 'through' the vcr, if you wanted to record on the vcr? Have you tried recording?
I hope I have been of help but please do not hesitate to ask if you have any further questions.

I appreciate your vote if you appreciate my reply and remember, even if you don't vote for me a please and thank you goes a long way

Sound but no picture on the vcr


Do you have a picture with just normal playback of VCR? If the answer is no, then it sounds like the head might need cleaning. Use Servisol video 40 see image below:

Power but no sound or picture alot of the time


the fault you are describing sounds like what we in the trade call dry joints, basically where components are soldered into the circuit boards in manufacturing, the joints become brittle and crack thus forming a poor connection which can vary with heat. well worth repair may need a couple of electrolytics aswell but i could do the job myself safely for under £100.

VCR not working with TV


What you state cannot be logical. If picture is freezing, then the VCR is at fault. But you state that the VCR works fine when played, and viewed on another TV. So, the only explanation I can think of is that there is some thing faulty with your VCR. Probably, when you play a tape, the picture freezes. This could be 'cos the Capstan motor of the VCR freezes. Common problem with aged VCRs. Just requires a spot of grease, and service. IT CANNOT BE THE TV AT FAULT!!!!
