Looks like you get to use your extended warenty. Your symtoms descibe an internal monitor inverter problem.

That would be nice.   So, you mean - - if it is covered under a extended warranty, use it.  But you are not saying that you know it is covered under some sort of defective unit warranty that is in effect regardless of warranty that came with the monitor origionally??

Yeah if you have remaining warrenty, it's time to call them and get it replaced, if not it's going to cost you.
