philips 42pf7220a/37 plasma green lines

[magnusius]

Hello,
I have come to the experts here for some help. I have a philips plasma tv. The picture is awful. Shadows are green and red making the picture almost look animated. I hit the darn thing a couple of times, and walla! Perfect picture. Of course today it is back to the same old picture. Anybody have any idea what the problem might be? Buffer board, logic, y sus? Not very tv handy, so was wondering if this is something I might be able to fix? Thank you very much for any info.

Check your power supply voltages. The specifications should be printed on a sticker on the plasma panel. Be careful, there are high voltages present inside plasma TVs, over 200 volts on some models. I would guess that because percussive repair worked you have a bad solder joint in there, probably on the power supply.

If you can solder, it is probably an easy fix. If not, eBay has that board for about $75.

Thanks, I check the voltage out and see what I get. Now if there is a discrepancy with the voltage, I am not sure where to solder.

A picture is worth 1000 words. Take a nice large (2000x2000) picture of the top and bottom of the power supply if the voltages are out of spec. One of us should be able to find bad soldering.
