After a power surge my tv has a blue screen on 70 percent of the screen.On the blue screen there is an error [Exception By UiTask Task] there is a line of what looks like code going down the screen...I was told the main board needed to be replaced.

I'm not an expert, but I have determined that the vertical bars that are often red, sometimes blue ... and sometimes both ... are related to a bad control board. I've also read that a common fix is to buy a repair kit with includes the ysus, zsus and control boards ... all replaced together. My experience was that after a month or two with the 1.5" wide stripes, that you eventually loose the entire picture and have sound only. MIne comes back, but won't stay working for very long and the stripes are always there (buy used to fade and flicker sometimes). I'm planning on replacing the control board.

Another "same probelm"
My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?
