My Samsung tv has a blue bar that spans the entire bottom of the tv screen. The blue bar is not solid blue, it has some white, bray, black distortion. The bar takes up 1/4 of the television screen and is only on the bottom. i have changed the Y-Main Board and the Y-Buffer Board as well as cleaned the ribbons with a special solution (Deoxit i believe was the name). But this made no difference. any assistance or ideas would be greatly appreciated. -Xavier Maltese

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

Do you have more specific information on your set, such as the full product model? Such as: HP-R4252X/XAA? What about the version?
This can help, because--as of right now--you are telling me that you put that Philips part into your Samsung TV. The LJ41-02759A is made for a range of Philips sets. They may work, don't get me wrong, but the part # for your Samsung set is: BN96-02033A
I don't have both these boards in front of me, of course, so I can't tell you if they cross or not.
Hope this helps.

I really do not know there is the "Stuck Pixel Fixer programs" I think that Program Breakdown another IC. For this issue is absolutely the Plasma display panel have problem. You shall exchange it.

The problem is heat!!! If the tv has fans they should be checked for normal operation,although on the early samsung models there were none, and the problem is that the panel drive buffers are getting to hot due to inadequate cooling. This is most apperent when tv is mounted to close to the wall, also external fan blowing on the rear left side will dissapate the heat. It is a problem on early Samsung and Electrograph 42 " plasma models. Hope this helps.
