Okay! The colortrak is alive again! Here's a pic!
I took the thermistor from a 90's Magnavox, as well as a new fuse. This thermistor is encased in a plastic shell, I guess to protect it. Bit of a PITA to fit it in, but lengthening the leads worked.
I've been running the TV for about an hour, and I've powered it on and off a few times during the hour just to be sure.
I also replaced a few caps. They didn't test bad, but they had seen some heat (shrunken wrappers), so I changed em out with some Nichicons that were in better shape.
Also, no Sanyo caps in this set that I've found.
