Replace the y-main board and the upper and lower buffer boards. 300.00 from Sanyo. Install them your self or get someone technically minded to do it for you. It worked for me. It's been 6 months and the t.v. is still going strong.

Hi, my Daewoo Plasma 42"


If the power light stays green then the current absorbed by the different boards appear to be normal. If that is the case then most likely you have a bad contact in the data cables or in the mainboard.
You will need to open the tv, inspect for damage and reseat all the components then (if that doesn't fixes it, you will need to extract the mainboard and check the soldering on the board and the status of the processor.

PINK SCREEN ON DAEWOO PLASMA TV


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

It fixed the problem and is still in working order im using it now as the computer monitor.

There is a small switch on back of main board, that switch must be on high level. If it doesn't solve problem then you must replace x-board (the right hand side one looking from the back TV)

Daewoo screen in a samsung


Theoretically yes functionally no. Not unless the parts are the same, chack the model numbers of the plasma screens. If they match you can change them out, if not don't try it.
