ASSY PDP P-Y BUFFER LOWER, Burned and need replacement.

Replacing the board would be best. You can replace the IC chip but there was a reason the chip burned out. You would need to diagnose the board and find the cause of the short that killed that chip and replace the other parts before you replaced the IC chip. By the time you do this you could have purchased the new board. If you are an experienced repair tech then it may be worth the repair but just for a user then no its not. Ebay has that board available from several sellers for less than $50.

HOW OLD IS THAT tv

If you had replace the y buffer board and it's doing the same thing, you might have a bad panel.

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.

YOU SHOULD HAVE REPLACED THE Y-MAIN BOARD AT THE SAME TIME, NOW DON'T TURN IT BACK ON UNTIL YOU REPLACE THE Y-MAIN OR IT COULD TAKE OUT THE NEW Y-MAIN

It looks like GUEST is a little anxoius about your helpful forum here.

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.
