SOURCE: LCD picture distortion.
This is caused by a failure of the main board. The failure causes the refresh rate of the unit to be off creating a trailing or ghost effect. This will require a technician to replace that board though. Hope this help.

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.

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.
Spoke with PartStore.com, rep stated 6871QCH038C (038C) is the superceded replacement for the defective prone OEM 6871QCH038A (038A).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.
