I have a Sharp Acquos 42" LCD TV. The picture is fine but the back drop screen looks like a wrinkled bed sheet. When you get a blank blue screen you can see it plainly. Sharp says they have no record of any such problem and of course it is out of warranty. The TV has less than 100 hrs on it and the problem went unnoticed as a guest room tv. Has anyone heard of this? Sounds like a manufacturing defect to me.
