Hi Frank, thanks for that, I dont have a manual for it. When I light the screen with a torch, initially there is a very faint 'raster' which seems to disappear after a few seconds. For info, Ive replaced the inverter board with a known good one with no results. The remote or keypad on the tv, have no effect on the set once its powered on, so I couldnt select any menu, even if I could see it with a torch. Does anyone know the service mode access code on power on?
