My tv hdtv-dlp has no sound or picture. When I turn the tv on the lamp light comes on and flashes for about 45 seconds to 1 minute then the lamp light shuts off but there is no picture or sound on the tv. I can access the menu, change the channels, and lower and raise the volume. but when I go to the tv/video button, when I try to scroll down from attenna it will not move. I have my dvd hooked up to video 1 connection but it is not recognizing it. The tv also will not turn off by the power button, I have to unplug the tv for the power to shut off. If anyone has any solutions it would be greatly appreciated. Thanks so very much. yes i have the same problem when i turn the tv on the lamp ligth tunrs on then all 3 ligths turn on at the same time but the tv never turns on can you help me? Same exact problem as rmilligan... turn it on, blue black screen than to strait black with a popping sound coming out of the speakers... i than unplug to turn off. Toshiba Regza 32''
This sounds like a dmd board problem. these are digital modules attached to the light engines usually. samsung, rca, hitachi, have shown similiar symptoms. some units have capacitors on the boards that can be replaced, but these are dual-layer pcb's that are tough to unsolder without proper soldering iron temperature and good small gauge solder-wick. or solder pump tool. the electolytic caps. are usually 1000uf / 10v, 330uf / 10v, or 470uf / 10v. alot of the time the capacitors will "vent" or swell-up on top which helps spot faulty component. we always increase voltage rating to 16v-25v for more reliable operation. always use 105 degrees high- temperature replacement caps.

Do you think it would possibly fix the problem if I bought a new power supply unit PE0246 V28A00030801 from eBay?
