I have a hitachi pj-tx 100 and at about 2000 hrs use (just out of warranty) a blue patch appeared all down the right side of the screen and across the bottom. I clean the filter regularly and have the fan set on high. Last night I watched the screen completely fill with a cappilary like motion of black lines! What is going on, I thought these were a top of the line projector??

I changed the bulb - thinking that might be the problem, but the blue is still there.

jimalvey,
The LCD optical block is getting worn out by the intense heat of the lamp. I would wait until Discount-Merchant starts selling the parts for your projector. I'm sure they would be reasonable on the price..

The hitachi's ARE top notch projectors.

Most brands have LCD panel failures, due to the heat over time the coating on the lcd panels burns off, the panels start to burn up, and it gets worse with time, and you notice it more when you put a fresh bright lamp in.

If it is just like recently, then you could have a bad lamp, that casts a bad tint. It sounds like fried LCD panels, a sure way to tell, is put up a white back-ground screen and see if you see discolored "BLOB" in the center of the screen.

keeping the filters clean, and the projector cool is the best way to prevent this.
