Mitsubishi 62" projection LCD

I have a the above mentioned set that has several green spots on the
screen that do not move or change. On all inputs. As light colors move
past them, you can see them. On a red screen they look blue. I was told
by a repair shop it was the light engine and it going to cost $1500.00
to fix it. I called Mitsubishi and bitched and they said they would
cover 1/2 the repair cost. I can get a new WD-57733 for $1460.00.
Should I? Is it worth fixing for $750.00? is it really the light
engine? I'm vexed and pissed... I didn't get the extended warranty cuz
it's a frickin Mitsubishi. I have a the above mentioned set that has several green spots on the screen that do not move or change. On all inputs. As light colors move past them, you can see them.

I have a Mitsubishi WD52537 with a green spot on it as well. It can be seen unless the screen is black. For the most part, it's not noticeable, but now that I know it is there I always see it. I've removed the front screen and back panel, but was rather daunted by the electronics behind the back panel. I've heard it can be caused by dust so I sprayed some canned air around, but no luck in solving my problem. If anyone knows any specifics on this, i.e. where to focus on finding dust, let me know.
