Fully solid state TV.

This is what I've been able to figure out. The subcarrier module has the tint pot connected to it. It changes the phase of the burst signal sent to the chroma board. Now I don't know if the tint shifting I'm seeing is being created by the subcarrier in the burst, or the chroma module. I would imagine that when the tint is adjusted, the burst voltage would change. I just wish I knew what the range of the burst voltage should be to know if what I'm seeing is in range.

When I adjusted the ACC, I didn't have the color bars up, or anything for that matter, as the instructions only noted to put it in align mode and do the adjustment. Now the APC did use the color bars as it was a purely visual adjustment. Once I get all the modules back, I'll try the ACC with color bars.

I went over all the boards for bad solder joints and found none. I'm going to check all the resistors next. For the video processor module, I am changing the electrolytic caps, but no other module has electrolytics.

I need to create a makeshift tool to speed up the cleaning of all the contacts on the chassis for the modules. Otherwise I'm just going to use deoxit on a tightly wrapped cleaning q-tip and wipe all the contacts and plug the modules back in.
