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.

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

Hello; I am John at J D Electronics in Poland, Maine. I have an LG TV that was donated to me. It is a plasma model DU-42PX12X. It had 1 inch wide red and green vertical bar on the right and a blue and yellow on the left. These bars appeared intermittently. pressing on the control board would make the bars go away. I have read many blogs on this problem and they all say to replace the control board located under that huge A / V input board ( held in by 4 screws on the large aluminum frame). The original part is # 6871QCH038A The replacement ends with a C instead of an A Aprox 90 to 135 dollars. This board is used on many different LG and Zenith models and is a HIGH failure rate part. I like to know WHY parts/boards fail and I found out why this board fails. There is a large square IC in middle of the board aprx 1 1/8 inch square. This type of IC is called BGA or Ball Grid Array. The solder connections cannot be seen , since they are under the IC . This IC was not properly soldered at the factory and that is why hundreds of these sets failed. I used my hot air soldering station on it's highest setting to heat up this IC . The IC must be directly heated from the top and some heat on the bottom of the PC Board. Liquid flux should applied to the 4 side edges of the IC prior to heating. The bars are now gone! To get to this board, remove all perimeter screws and all middle screws of the back cover. The A V board will hinge back to expose the control board if you unplug the cables to the side inputs and the one to the button board. The set will still run face down on a table with something to prop up the bottom screen so you can watch the bars. If the set was run for a long time with the bars, there will be some darkening where the bars have " burned" the screen. This is perminent, but usually acceptable.

The lines on the screen show that there is a poor connection with
the flatcable on the controller board.
Ok lay your flatscreen on a table or on your desk.

First remove the backfront cover.

Then you will see the input board frame you've to remove this first.
When you removed the input board you'll see the controller board

LGE PDP 040602
MODEL: 42X2
BOARD: CTR_LVDS
PART NO: 6871QCH038A
LOC NO: 1XXX


The connections you have to check is P105 and P106.
These are the flatcable for the leftside of the screen and
for the rightside of the screen.

Try to keep the input board up to 45¤ and leave the wires connected.

Now put the power on and see for your self when you push on
the flatcable you will see the lines disapear and the screen show
normal asual.

This indicate that the soldering points are bad to resolve this you can try to resolder the soldering points or you replace a new controller board this part you can find it here.

I hope this will help you out.

I had the same problem and resolved by myself so its easy to do
