Question about Televison & Video

Open Question

My 9 year old NEC PX-50XM1A plasma display powers on with only the bottom half of the screen lit up. I have to power cycle it 5 to 7 times before the entire screen lights up. Very strange. Any suggestions, other than "scrap it, it's 9 years old"? Thanks.

SOURCE: NEC Plasma Sync 42MP3 Problem

Hi, This model has some design flaws and yes NEC admitted to them a year ago. The problem with your monitor (hopefully) is a bad power supply. Have a Tech with a voltage tool check the boards as well as the connections Reason, this monitor generates a lot of heat ( no cooling fans) primarily at the power supply and sits there. So the wires tend to go weak by the heat build up. What the problem is the power is not going to the correct board in the right voltage. hope this helps out!!!

Power supply issues


hi there, i recommend replacing the entire board. once you have a short like this, the micro board itself will become useless. the thin micro circuitry has become separated within the layers, preventing a closed current transfer. its best to order a new canvas so to speak.
