Re: samsung 50" plasma wont turn on

Another thing that's complicating diagnosis is that the TV was set up to use external speakers. Is there a way to reset the TV so that it uses the internal speakers instead? Kind of difficult without being able to see anything on the screen.

Re: samsung 50" plasma wont turn on

I have this exact same TV, Samsung PN50C450, which powers on, but has a completely black screen. I measured all the voltages for Va, Vs, Vsc, and Ve, and all of them checked out fine. The main logic board's status LED blinks every 1 second in this state. I also tried disconnecting the X/Y-main from the main power supply, with no change in behavior except that the status LED stays illuminated for 5 seconds and blinks for 1, and the power supply voltage drops off after initially going up the normal level.

Can someone please provide...
