Hopefully there's some ebay part to change it with cheap. Canon AFAIK still repairs them. Get estimates.
I have had my camera for almost 7 years now. It was in perfect condition when I got it but I put it away for a year or so and when I took it back out, the screen had a huge brown splotch on it. It looks like a coffee stain would look on a piece of paper. It's a Canon EOS Rebel XSi. Does anyone know what is wrong with it?
This is what it looks like.
