Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines. I turned the tv off and on but the problem persisted. Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.

sadly no.
either your panel has been hit and damaged or the panel itself is failing.
without some sort of warranty coverage, your repair cost would exceed the price of replacement.

You will need to replace the control board and your TV will be better that a new one.

I had the same issue. I could get the tv to work intermittantly by pressing on the boards while playing. This points to bad solder joint, so I resoldered every molex plug connector, and it nows works like a charm.

hi..the probelm is due to the video circuit board.
only when you have a problem with the video
circuit board you will get such type of faults.so
you have to check the video board immediately.
check it out..
thank u..
rate me..

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.
