IF THE LINE IS ABOUT 1INCH WIDE THE CHANCES ARE IT WILLBE YOUR PLASMA DISPLY THAT HAS GONE . WOULD BR CHEAPER TO BUY A NEW UNIT . HOWEVER TRY RINGING HITACHI EXPLAIN THE FAULT COMPLAIN THAT IT SHOULD OF LASTED LONGER THAN THE WARANTY AND SEE WHAT THEY WILL DO ABOUT IT

Follow-up. I found the slip on which the LG tech wrote down the part number for the board to fix the vertical red stripe. I was mistaken in my previous post. It was not the Z-Drive board. The board you want is:

X DRIVE BOARD; Part 6871QRH043A
Type in the part number in a search engine and yuo will find multiple places to purchase. Ebay may be the cheapest. That's where I got another part which got my picture back. I did not buy this part myself because now that I have my picture back, I do not want to screw it up, so I live with the red stripe.

Hi
If there is no picture behind the stripe and the edges are well-defined, then one of the display driver ICs has failed. Philips displays can be made by several manufacturers - usually Samsung. The ICs are bonded to the flexible ribbon in most cases, and replacement is an expensive specialist job - and in many cases is simply not possible.
A shadow on the picture is much better - usually due to interference.

I've been fixing a DU-42PY10X with the same problem. I checked around online and with a friend in the business and both suggested that it is indeed the "Buffer Logic Right" (for the left side). I took the unit apart very carefully and checked the serial number sticker on the board for a number like 6871QRH043A. 6871QRH043A is the part number I need, but it is probably different for you.

The part looks like this (http://www.discount-merchant.com/We-provide-factory-original-parts-worldwide-p/1036658-lg.htm) and is found buried under several boards as well as under one of the main structural support bars. I had to take out the two system boards and their enclosing box, the power switch board, the two support bars and a giant heat sink spanning from the left to the right side at the bottom. Under there I found both of the vertical buffer logic boards (left and right sides). There are nine ribbons that have a flip-up snap to hold them in place to each logic board. And don't forget the 15 to 20 other cables that needed to be removed to get down there. And watch out for the three high-voltage boards (that have very large electronics and heat sinks) -- They will still hold an electric charge.

So, you could replace the board yourself if you are very organized and cautious. There are a lot of screws and a lot of wires and a lot of stuff to avoid. You may be able to get the part number by calling LG's parts department. I got my part for about $90. If you don't have the affinity to take apart consumer electronics already, then I'd advise having someone more experienced do it. I've taken stuff apart for fun for years, so it takes me about two hours to fix it. The $500 labor is steep, but it is that high because of the high voltage concerns and to pay for any mistakes they make.

If you feel you are a capable tinkerer, I'd order the part through them or through LG's parts department and fix it yourself very very carefully.

You could have one of three problems. One is really expensing to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went back. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable and clean it off a bit and put it back. If its still there, you have a deeper problem.
