Ok thanks for the info Now this is an indication of convergence issues(3d effect) the bowing issue idicates a complete loss of convergence power. which possible could be the convergence ic or the actual power feeding them. im feeling like it might be the ic overheating these get very hot. now the bad news. this is a set that is very difficult to work on. Rca has compiled a long list of problems with this set. getting to the chips is a chore. i cannot recommend repairing this set. I know no one likes to hear this.
there are several rca issued suggestions. the top one isChange C19542 on the Digital Convergence PCB from a 10uF 63WVDC capacitor (214698) to a
470uF, 25WVDC capacitor part number 214746.
Also change the 24V zener diode CR19720 (226446) on the Convergence Power Supply board to a
30V 500 milliwatt zener diode, part number 231211 this
but as i said this may or may not be the best solution

You were right about it being a heat problem. I took the lower back panel off and laid a small 10 in by 10 in box fan blowing down on the components, and the TV has never messed up again. I know this is not a factory fix, but it works. For a TV that could not run 15 min. without going wacky, now it runs for 8 to 18 hours a day and never skips a beat.
