I realize that this is a old post, but for the sake of anyone else with this issue; I'm visiting my mother and found that she has the same issue. After some investigation, I've been told that this is an issue with something called the "Control PC".
The service tech told me that if it was colored dots, the issue is the "Y Sustain", but white dots are due to the Control PC.
Rough estimate for repair would be in the range of $300 - $400, for a repairman to come out and fix it.

The TV requires restoration due to jammed setting either because the remote control was damaged or power function buttons have been pressed too frequenly.
The following processes are recommended

If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.

You have a major problem. I have had the same problem and in the end the tv was
written off. luckly I had insurance. I even spoken to the LG bods and they did
not know. The only thing I can tell you is that its NOT an aerial fault its the

Thanks for contacting Fixya Support, I am glad to assist.
What is more than likely the issue is that your HD Plasma TV may have a burnt-out Inverter or bad Inverter cable, as these are two components are key to the back lighting necessary for illuminating your plasma screen.
In cases like this, it would be advisable for you to contact the manufacturer (LG) first, to see if there are any known issues they are having with your model of plasma TV, or if there have been any whole unit or part recalls for this model.
The next step I would recommend after contacting the manufacturer would be to take your Plasma TV to a local TV repair shop for a least a diagnosis to see what the cause of the screen black out may be.
This does appear to be a hardware issue, but check with the professionals on this problem, is my recommendation.
I hope this helps.
