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.

a4.. there are 2 of them, upper and lower buffer boards.. they control the top and lower half of screen devided horizontally, i have had many run ins with these sets. and usually the buffer boards arent cheap.
they plug into the ysus( y sustain).. its possible your y sustain is blowing the buffer moduals because one of its i.c.'s under the heatsink has popped on ya.. effectively creating a short that blows the buffer boards.
remove the buffer boards, turn tv on... feel the 2 silver heat sinks on that y sustain( beware dont zap urself.. just the tip of your finger on the heatsinks)
you may find that one is cold and one is hot...if so, you need a new y sus and probably to replace the buffer boards the a4 upper and a4 lower.
If you get a new ysus.. plug the a4 upper and lowers into it, look at your picture.. if ur missing the top half the top buffer is blown or lower half the bottom buffer is blown. or..no picture they could both be blown..an easy way to tell if u have no picture to diagnose is..touch the heatsinks that sit over the chips on the buffers..if they are red hot.. they are bad and shorted internally.

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.
