Google shows some possible solutions.LINK,one link mentions that the monitor is to close to the tv.
I suppose you didn't ask the repair shop what the repair was.
I have a Gateway7330 laptop. It's about 2-2 1/2 years old. The monitor flickers. It seems like it's a loose wire, if I close the monitor and then bring it back up and adjust it to a certain angle it will stop the flickering. I need to move my monitor around a bit to make it stop. Once it is in the right position and I don't move it at all it is fine.
It of course is out of warranty. When it was under warranty, this was happening and I sent it in to be repaired, it's now doing it again.
Any suggestions-is this an easy fix or should I bring it to a professional?
Thanks for any help with this.
