    I have a Gateway 46in. HDTV Plasma. The screen went black while I was watching it and I cannot get it to show a picture since. There is power, but just a black screen.

Just fixed my Gateway P46M103. I was getting a picture, sometimes it was clear as long as the picture scene didn't change - if the scene changed I would get white lines up and down the screen. Seems there is a problem with the power board and if not fixed in time can fry other boards or components. If you know how to work on electronics, download the service manual, look over it so you can identify the boards... Remove the back and take a look at the YSUS connector on the left side of the power board. Mine was arching when I slightly moved the cable - WARNING - DO NOT DO THIS IF YOU DON'T KNOW WHAT YOU'RE DOING - (THERE IS 160vdc and it will BITE YOU) - Anyway, remove the bracket and the board and with a magnifying glass inspect the solder points for the connector - I had five cracked/cold solder joints causing voltage flux. I verified and adjusted the Vs, Vw, and Vxg to specs with a DVM. TV now looks excellent.

Gateway 46 in plasma


It sounds like the gas in your screen has exhausted it's life. From the information I have gotten from different manufacturers, there is about a 5 yr life expectancy on the screens of most plasma sets.
My guess from the symptom you describe is that you will need to replace the screen.
Thanks/mike

okay on your remote you probably have an input button, if so press this slowly and cycle through the inputs and you should find your picture again.
