Hello everyone. This tv has an intermittent problem, when you first power on everything is perfect, after 1-5 minutes picture disappears but sound stays.
If left on, picture may come back after a couple of hours or not. before picture disappears i see black streaks across the screen. On all external inputs picture is normal and never disappears. I tried heating and cooling all modules,no noticeable effects. All voltages from power supply are dead on.....have no idea where to go from here, Hope someone can help. Thanks

Hi landyboy, have you repaired this tv? Was it the panel ? I have the exact same model, after changing the caps on the power supply it comes on showing pretty much like yours. I managed to get more brightness by adjust subrightness and subcontrast in the service menu, but still looks like crap.Right side of the screen looks brighter than the left side.
