Default Re: Help with Colour TV set identification??

Cheers guys!

It's all back togther and all the plugs and sockets are (hopefully) in the right place.

I bottle out from switching it on again as (a) I ran out of time and (B) since I have no circuit and the "+B" pot is set right at one end of it's travel I am a bit wary. I think a previous repair has resulted in the replacement of four bridge rectifier diodes on the power panel. These shouldn't affect the output (there is a regulator transistor) but it would be good to get it right. Convergence is likely to be a faff as the controls are all on the board behind the scan coils. It will need the use of a big miror.

I do have another JVC set, can't remember the exact model number at present, with a similar circuit but an 18" tube with separate convergence panel. There is service info for this one, so I will perhaps compare the two.

This one is even dirtier inside a tribute to how well it had worked over the years - it still worked when I got it and it's turn to be "done up" is approaching
