Sounds similar to a problem I had , haveing bought and install components to repair/upgrade the power supply I still had the same problem. I solved the problem by adjusting the LOPT line output transformer be carefull of the high voltages even when powered down, the lopt has one adjustment just turn it as little as possible, power up and see it solves your problem, I'm not sure in which direction but try anti clockwise first. Mind only needed the smallest of adjustments. Make a note of where it is before you make any adjustments. My TV been as good as gold for a couple of years now
