try relocating the tv. it could be magnetic interference. also make sure that there aren't any speakers too close to the screen (other than the builtin ones of course.)

Bad installation of the timer control board.
The cable conected to the control board needs to be checked to make sure it is properly conected.

Check the controller board, 6871QCH038A. This board is one layer deep into the assembly after the cover is removed. Gently lift the covering circuit board back plane to access.

To do this direct a blast of cold air unto the large chip in the center of the board. If the picture comes back on then you have found it. This means powering the TV while open and this means danger to the novice. Voltage can end your life when you become the circuit path.

Order Part number 6871QCH060Q as the suitable replacement part to this circuit board.

Could be the screen burn from watching T.V. on a show and the thing burnt in (in this case the colors, yes it can burn colors.) and there's nothing you can do. The insides of the T.V.'s have plasma gases which can flow out of control.

What board did you replace? Sounds like you're got a problem with your X-drive board(s).

Pop open the back and double and then triple check all your connections and make sure they're good and tight. Especially those TCPs at the bottom that plug in from the screen itself.

Hi,

It seems that some parts are having a problem by warming up the temp.
If you're a technician, try some coldspray on the capacitors of the power supply.

Cheers,
Gerard

Well if it's old it can be burnt in from something being on there for too long. The inside of the T.V.'s have plasma gases and they can run out uncontrollably too. Sorry, but you can't do anything.

Yes, the "PIP" is the display of multiple channels at one time. On your remote you need to go to the zoom pip button and press it, if nothing go to the meno then look up the "PIP" tab and go there to try to zoom out.

Check within you area for a reliable LG repair center. To fix the problem of the blue, red or green vertical line you just need to replace the control board PN 6871QCH038C. The part cost about $150.00 and a honest repair center should not beat you up to bad on the labor. Good luck and Good viewing.

If it's new you should be under warranty.

If not, you need to replace the Power Control Board 6871qch038a

My Plasma is a VIZIO P42HD but all the components are LG.

Spoke with PartStore.com, rep stated 6871QCH038C (038C) is the superceded replacement for the defective prone OEM 6871QCH038A (038A). They and others offer the 6781QCH060Q (060Q) for $50 - $100 more. I opted for the 038C, but I was concerned about the title of the part which states "HAND INSERT"... PartStore.com rep stated it is in fact a board and there is no soldering needed, just "plug and play". DONE, paid only $120.95 + next day shipping for $29.95.

Since I took the TV apart before, it was a breeze and took about 2 hours, start to finish.

Important note, remember to remove the two 1" square spunge type heat sinks/pads the new board needs those for a proper installation and protection of the certain component.

Also you need two small zip ties to replace the ones you are going to clip off.

Added Bonus, the new board fixed other issues:

1. At times I would get a squeegly red line go across the screen. I thought it was the source (cable) but it is gone now.

2. Screen Shift, when I use the XBox for Games or DVD/HDVD the screen would shift. Very annoying, prior to swap out, recently the screen started to shift watching cable. Now it is no-longer an issue.

I am really pleased with my DIY repair and wanted to share.

The damn Vizio Out of Warranty Service wanted $360 for a service call which included the part for $125 plus they take my bad board for exchange.

I have a Vizio P42HD but once it is taken apart, it is all LG components.

It is your Power Control Board 6871qch038a. The solders are so small it isn't worth trying to re-solder.
