If its one large line an inch or two you have a problem with the x boards. If its several thin lines multiple its going to be in your digital/main board.

Line, faults & possible causes to LCD & Plasma TV screen are given with illustrations. You can get an idea about the fault to an extent.
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.
hi, As you mentioned its sounds like the X buffer (Right and left) of your tv is faulty. There are two boards in your tv for driving the X plane of the plasma panel. Normally you can find these board on the top or bottom portion of the TV. . Its part numbers are Right buffer board is 6870QSC107A 6871QRH073A and Left buffer board i EAX35683901 EBR35855501. Before purchasing the boards identify which board is faulty. That you can find easily. Check which portion of the screen have vertical line in right or left side of the panel. The board for that side is faulty. You can find these boards on the following link.
Don't replace anything, Vizio has issued a lifetime warranty for this set because of this problem. No joke, call the customer service line and tell them you got the pop of death. They'll send someone out to 'repair' the set free of charge. If they can't fix it they'll give you a new one. Even if your mfg purchase warranty has expired. Call them and post the results. I've been fixing TV's longer than I care to admit and this is the first time I've actually seen a company stand behind their products like this. I bought a broken tv with the intent of fixing it and after replacing almost every board I could only manage to get the vertical racing stripe line, except mine was purple. I put it all back together and called to find out if there was a recall on this set and within 5 minutes the (Actual English speaking) gentleman told me to sit tight and he'd have a repairman come and do his thing. He did, and long story short, he couldn't fix it. Last week they delivered a new TV to replace this one. I was shocked. I think Vizio will have all my future business.
Good luck.
