Hi,

I notice last night that when the screen is completely black like let's say when you switch video inputs and there is no video signal, anyway the whole screen is black but I notice two areas that look like a white cloud not really symmetrical figures but you know Not as black as the rest of the screen, is not really too noticeable but you can tell, when the tv is getting video input the tv looks fine no trace of this "white clouds" Is this normal in LCDs?
Please help.

I didn't find the right solution from the Internet.
