LG plasma interference problem

My boss has a 42" LG plasma TV. I was round there last night and noticed an odd interference. You can see it most clearly on the blacks, it is like a load of red snow all over the screen.

I took all the inputs out so just the power cable was connected and the interference is still there.

Now the only possible explanation I can think of is that at the end of his road (very close actually) is a chuffing great wind farm with those massive fans you see about. Could this be causing some kind of power supply interference?

If this is the likely cause, can you buy something to put between the plug and the TV to filter the power?

The answer is no

The dots you see are almost certainly due to control board voltage imperfections

Have a look at the LG threads this will have been mentioned before
