look in the mst-??? module
its the tuner control and lots of bad solder joints in there.
a few larger caps go bad in there too.

Don't think so.

I doubt that the set used an MTT Tuner,I think it is probably a ctc-146. Most likely, that problem is because the video buffer transistor has shorted, or the +200 volt line has taken a dive.In any case, it is NOT hard to diagnose-- IF you are somewhat familiar with tv sets.
