Tosh Panel discoloration - Can you help?


Active Member
My old TV is now being used as my PC monitor. I have noticed discoloration of the screen at the edges. A picture is attached. Can anyone think of what the problem is?

I know it's not the computer - as if I take a screen shot and move it to another part of the screen it's fine.

Toshiba 23WL46 Pc input at 1280x768.
