Re: Blue patch on left side of screen

I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.

The top of the screen is slanted while the sides of screen and bottom are even, causing the right hand side of screen to appear smaller than the left. Anyway to fix this?

Sounds like a "keystone" problem. Your projector needs to be oriented to the screen in an exact manner. Manufacturers provide "keystone" correct to adjust for mis-alignment. If proper orientation is impossible, use the keystone correction of the unit to adjust your edges.

Infocus DP8400x blue hazey line

this discoloration is the begining of the lcd panel being thermal damaged. this happens when the projector is being used for a long period of time and then being shut off using the switch on the rear of the projector instead of the on/off on top or the remote. to fix it it will have to be replaced. very expensive major repair.
