Have no power light no standby light no display or sound. I've pulled back checked relay board it starts voltage come on then voltage drops relay chicks no tv. I've checked power supply board I find no blown caps will replace all of them to night see if that helps. TV was working fine then had brown out and TV did not come back on have looked though a lot of threads and read tons of stuff no one seem to have a handle on this. The main problem seems tobe the power supply or some board pulling the power supply down. I bypassed the relay and the power comes on now but no picture no sound. Board leds light I seem to have voltages on the power supply need some input on this one. PLease send some good input I've read your forums on this and I find that there is not much helpful input. If you don't no anything about plasma TVs don't reply I want to fix this TV I'm not sending it in to be replaired and wait 6 months or longer to find out that the service people don't know what they're doing that's why I have this TV the service techs have no clue what's the problem. There fix is to replace it. I've worked in the electronics busniess for 30 years and it can all be fixed with the right knowledge
