Depends on what area the line is in the bottom half or top?

Hi: We had this problem under warranty, and tech installed the following to solve it: Parts BN96-02033A, BN96-02034A and BN96-02216A. This solved the problem for 2 years. I now have the upper half going black now and then for 2 to 3 seconds. I am ordering these parts from www.partstore.com and will just plug them in. Better than a new tv.

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad

I just had my HP-R4252 repaired on 12.05.09 with a similar problem. The picture is covered in horizonal, broken lines and the color is predominately red. They lines are grouped together in large bands across the screen.

The tech replaced the Y-Buffer boards (Up) and (Low) in about 20 minutes.
