Hello, Has anyone ever had to replace the Part

From Wikipedia:
"A plasma display panel (PDP) is a type of flat panel display common to large TV displays 30 inches (76 cm) or larger. They are called "plasma" displays because the technology utilizes small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamps."

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.

It depends on color of line.

if the line is black, need to replce PDP module(panel)
But, the line looks like noise, need to change the main board.

Try to replace the Logic Board, about 50% chance to fix the problem.
