I have obtained an old color tv with large screen.it has discolorated right side of screen and upper left corner. when i display menu with blue background, the right side goes green and the left corner goes purple/red.Replacing thermistor and 10 cold starts didn't help. So what can cause it?????? This tv has replaced flyback. I think someone unqualified turned some pots in V and H deflection circuits. can this cause discoloration?Or what about higher/lower high voltage (maybe bad flybackreplacement,but picture seems not to be larger or smaller)?I was told that the speakers can cause this, but i think this annoying discoloration can't be from factory...Has anybody idea? THANKS.
