TV goes into shutdown. Removing the third convergence plug stops the TV
from going into shutdown. Re-plugging it causes the TV to function
normally, for a while. I can turn the TV on and off for a number of
times, then it goes back into shutdown.
It would appear that one STK 392-110 IC was changed. So I interchanged
the two ICs to see if the problem would move to another convergence
plug. It didn't. I'm thinking of changing one of these ICs.
Any opinions on this?

Change Both and check the low value resistora in teh convergence output
circuit. Also check the convergence yokes, either by ringing or with an
accurate, low range, ohm meter.
