20 inch GE CTC166CS chassis red smearing but strong CRT

[MRX37]

So here is where things stand with this thread:

TV is probably not fixable due to a 64 pin u1001 IC that is frankly not worth the labor to try and fix.

The CRT is verified good, and verified because I actually got to swap in another CRT and it had the exact same issue. At this point the odds are it is that IC. So that is my diagnosis. And at least I came to a diagnosis.


Now I do have an addendum. This CTC 166 has one of those degauss thermistors. You know, the ones that like to separate from their leads? And it separated from the leads.

I replaced it with the thermistor from the CTC 146 donor chassis, which is a much better thermistor, in that it has a coating on it like disc capacitors have, to keep the leads from breaking off.

The CTC 146, despite being a cheaper set, has a better degauss thermistor than even high end RCA sets.

Go home RCA, you're drunk.
