Your on-off problem was most likely solder issues around the transformers. The diode connections off of the power transformer were usually the cause, very common issue back in the day.

Yeah, the SIP board was the first thing I checked. Diodes check out and I added new solder and removed the old glue. Unfortunately, after using my TV over the long weekend, it began turning off & on again. I guess it's still possible one or more of the diodes is going bad even though it tests OK out-of-circuit.

On one of the occasions when it shut off and came back up, the colors were all messed up. I'm going to check the components around the degauss circuit. Maybe the power is fine but the degauss is triggering when it shouldn't. I do hear what sounds like a relay that will click when the tube fully turns on, although I don't know where (or if there even is one) the relay is located to test it.
