Yep. The problem is those lamps. Try this one , if you still have monitor : turn on your lcd , then wait till screen turns off. Then take some light source like desk lamp or high power led , then touch your screen with it and you will see in that place where you light your desktop , or whatever you left before monitor "turned off". If that so , problem is with matrica`s lamp`s. If you cant see any signs it may be matrica problem , then i suggest you to buy new monitor , they are not so exprensive these days ;]
