We had something like this recently, with a Sony TV, color was all blotchy
and even degaussing the tv didn't clear it up. Turned out that the degauss
circuit wasn't activating long enough, might want to see if there is a
timing cap on the relay drive circuit.

> No speakers are near the set. When he first brought it in, I could tap on
the relay and it would do it. I replaced the relay and tapped and it seemed
ok, customer brought it back next day. Degaussing only occurs when relay is
activated by micro. There is a thermistor in the circuit, but I don't think
it's the problem since one side of the coil goes only to the relay. Neil
