Common problems with these, usually customers here a loud pop. then the screen goes blank. I would try...
Some of these have a 4 pin test on the control board that you can jump with solder to get test pattern. If you get it to do that then these boards maybe good and would replace the control board. if nothing happens, then
the upper & lower drive also the Ysus and Zsus boards all at the same time.
last could be a defective panel.
hope this helps. p/n are on all the boards.

    not test pins are usually a 4 pin connect on the control board.

    usually pins 1&2 shorted gives test pattern.

Howdo you fix and picture that is fuzzy and whiteallthe time i have a 42 inch plasm tv


If the Vs and Va voltages to plasma panel is abnormal, this could happen. Check these voltages. Both these voltages are critical, and should match exactly the same as marked on silk screen at the back of the display panel. If you wish to get some details; check the site linked here. Pull up older posts.

How do i turn the television on i just bought it from the store


Either by your remote or manual. Some models have a master rocker switch close to the ac input where your cord plugs into. That kills all power to the set for vacation purposes.

I have no picture but i have sound any suggestions


Replace 6870QZE013C or 6871QYH053A (more likely).

The second is the Y-Sustain board, located to the left of your TV when looking from the back.

This is the one that usually burns and the fuse on it is likely shorted. Do not replace it, it will burn again.

There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable near the black lines. Unplug the ribbon cable and look for black chips on the underside of it, I think they say 100 on them, you need to resolder both ends on each chip. Should fix the black line issue.

Picture on big screen


Chances are, if it's an older set, componants have changed value through use over time, which also includes the picture tubes and associated driver circuits. The way to compensate for this color drift is through adjustments. Either turn the red down a little, or turn the blue and/or green UP. Be carefull though as there are potentially dangerous voltages in and around the circuit boards and picture tubes.

Screen full of moving colored lines


I would suspect bad solder connections allowing a ground to "float" It is a common problem with the model P42W24BX which I believe uses similar circuitry as your model. An experienced repair shop should be able to get you fixed up.
