I am looking to service an older B&W TV and would like to use my Sencore to do that, but it may require servicing as well as the TV...

Thanks!

Appreciate the manuals, might you have the schematics too?

Thanks!

I only had whatever was at the dropbox link. I don't remember who scanned it or where I got it from.

If you find the schematic, please let me know and I'll add it to the dropbox folder.

Sorry to resurrect this thread but I’m having a problem where my VA48’s Chroma burst pattern is not displaying. All other patterns show except that one. Any suspect electrolytics have been replaced throughout the boards.

I don’t have a schematic, so I’m kind of working blind. Do the xtals in these go bad?

Well , you don't need a schematic to know what is written on an electrolytic capacitor. If you already know which part is at fault , if you know how to solder, this shouldn't be a problem for you.

Personally, I only need a diagram if I do not know the problem of a particular brand or if the brand of a device has recurring problems. Otherwise I only change the capacitors of the missing part (if I know it's from there) otherwise, yes you will need a schematic.
