I've had a 60735 for a little over a year that has been perfection until recently. When viewing a movie with dark scenes there is a big white spot that starts in the middle and kinda moves towards the top right. I'm not sure when the problem started but I first noticed it when popping in one of my Star Wars DVDs. The starlight background looked washed out on the right side. I switched it to a completely black screen and it is VERY noticeable. What could this be? It's very uneven in it's shape.

Any fixes I can do?

P.S. I opened the side panel and checked the foam and it doesn't appear to be leaking from there.

It sounds like you have a problem with this display that will require service. I recommend you contact a Mitsubishi authorized service center in case the repair is expensive in which case, If you have the sales receipt, Mits might help.
