hello. I'm wondering if anyone can help me with this issue. I am starting to get my home theater setup after many delays now. I am using a mitsubishi HD 1000U that is going on two years old now. I have noticed that the sharpness level has decreased somewhat and am noticing vetical and horizontal lines in a grid pattern on the screen. The lines are quite noticable and somewhat blur the picture in a fashion.Have tried to tweek the sharpness but no real joy there.Any info or help would be greatly appreciated.

If there is a user's thread for this projector in the digital projectors areas, you'd be more likely to get an answer there. Since yours is a slightly older model, you'll probably need to do a search for your model number.

Can you give us photo?

i can try and do that. might be morning before I can
