Was adding external speakers to my Dell W4201C plasma TV. Both were working well. While mounting the speakers to the wall, the right side speaker wire got pulled tight, and sound quit coming out of both speakers. I unhooked the right speaker to deal with the wire length, and the left speaker sound came back on. When I plug the right speaker back in, both lose sound. This is repeatable.
I checked the speakers, and they both work fine if plugged into the left channel jack individually. I measured the resistance of the speaker jacks on the TV and found that the resistance is pretty low (200-300ohms) on the left side output, but the resistance is open on the right side output.
Any ideas....?

Well, since this post, I have lost picture quality - looks like very bad contrast, and have a couple of very large black splotchy areas. Thus, I have not tried to remove or repair the audio board.
If I can get a little guidance with the video issue, I will work on both at the same time. Appreciate the help. Thx
I replaced the main logic PCA LJ92-01270E and that did not resolve the video clarity problem. I was able to go thru the menu and put the TV into "Plasma Conditioning" Mode.
There is a huge black patch in the upper left corner and another about a 1/3 of the way from the right side. Each extends from the top edge at least 12". In the lower left corner, there is another patch, but not black. The rest of the top half of the screen is white with red dots dancing around in it. The bottom half of the screen has pink/red horizontal lines overlaying the white background.
Is the plasma screen toast ?
Is this what they look like when they fail ?
Please help !
