    Broken 42" Plasma Screen

    I have a 42" plasma TV aprox 2 years old. It branded as a cornea and supposedly manufactured by LG (glass) and zenith (components). Anywho the thing was on one minute and the screen blacked out the next.

    When the unit is powered on the screen stays black, but if you disconnect what I would call the secondary screen interface board - it's between the power supply and the side of the screen - an image comes up, although it is dim. That secondary screen interface board is relatively simple, and you might be able to find the individual component on the board that is malfunctioning. Something on the +175VDC rail is shorted to ground.

    I never found out how much a secondary controller board would cost, and would not guarantee that fixes the problem, but I would like to sell the TV as is to someone that may know how to fix or whatever, maybe use it for parts. I know the glass is very expensive on plasmas. I do not guarantee that you will be able to find a board for it.

    I would like to get $350 for it, which includes a table top stand, the wall mount remote control, and product maunal. The wall mount pretty flush and the tv is less than 3" thick.

    I'd like to have it picked up locally. It can be picked up in Gainesville, Florida or Miramar (Ft. Lauderdale), Florida.

    its not the screen itself, there's a board between the screen and the power supply. When I hook it up, the power supply goes into protect mode. When I leave it disconnected, the screen comes on but is dim because it doesn't have one of it's controller boards hooked up

    it's not even really a controller, as far as I can tell it just switches 175 volts on and off really fast, there aren't many components on it

    Yes, and I drove 60 miles out of my way to pick it up, and then paid $50 in shipping for a part (the power supply) that it turns out wasn't even broken. I'd like to recoup that cost. Also when he sold it the end user didn't know if the screen was damaged. I can tell you that the screen works but is dim

    I wasn't saying you don't have the right to ask for that much. I understand. I was interested in this before and am still but I have since spent the needed cash.

    So you didn't take it anywhere? You just tried fixing yourself?
