Daewoo PD42S20W has scrambled picture

I just "inherited" a plasma from my boss. He said he thought it was junk because someone had laid it down when they delivered it. The screen comes on clearly sometimes, other times it is scrambled. The "scrambled" picture really doesn't follow any particular pattern. I know that the machine is out of warranty, but was wondering if it's something I should look into fixing.

    A little more information about this problem. I can tell that there must be a short somewhere, because I can do the "whack" test and get the screen to clear/scramble. Though I work on electronics for a living (mostly copiers and cash registers/POS), I can't seem to find a schematic for this model since it seems to be one of their older plasma models. If anyone knows how to get one, that would be appreciated.

Sounds like your panel might be going out or a faulty video card. This is the first time I have heard of a solid pink screen on a plasma. Usually this happens on LCDs, though they sometimes go white and stay white, which does signal a bad panel. tv needs repair

SOURCE: plasma 42" daewoo edtv black line down middle

Attempting the solder fix is a big undertaking, gaining access to the components is a MAJOR undertaking, and probably not worth your while.
If it is simply one line you might try the baseball Bat fix....
In reference to the "basebal Bat fix" it works on occasion by using percussive force to realign the ribbon cables.
DO NOT use a baseball bat, but use a rubber mallet and with the power off tap gently directly above and below the offending line.
Its worth doing this if yo cannot live with the line.
If you can live with it, leave well enough alone!

I got on ebay and bought the item from a store for 125 dollars used tested good with 12 dollar shipping, I put the part in myself it was very simple just take your time dont try and rush you have to take the actual bar the stand hooks onto off and the 2 boards going into the ysus board. It fixed the problem and is still in working order im using it now as the computer monitor.

Sounds like it's on the wrong input, maybe it's analog tuner. Have you tried changing it's input?

After being on for a whilemy plasma tv picture scrambles. After it cools down the picture is restoredwhat could be the cause

Your plasma is over heating! This is not a good situation for the tv as the components are only rated to their highest temp of 105 degrees C. (IF there are quaility parts inside). Some plasmas are only rated to 85 degrees C. I would recommend installing an internal fan or keep a fan behind the plasma to help cool it during its' working hours!

Please rate if this helps :)

When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Broken glass on plasma tv

The glass is part of the screen. It will probably cost more to buy the part than a new TV would cost.
