There is a burn spot on one of the light filters located next to the blue lcd panel. it is caused from excessive heat and dust. unfortunately, you'd need to replace the entire optical engine because infocus does not sell individual optical engine parts.

Black spot in the middle of the screen looks like it has a burned spot


Yes if it uses 3 picture tubes one is burnt dead center--cover the lens one at a time to see which is causing this--permanent damage caused by a arc.

If a newer set you have a display unit with a dead pixel.

Sharp notevision xgnv6xu oval yellow spot


I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben

tv is almost 2 years old. i called hitachi and they advised to call a local repair center to check the tv...they confirmed Optical Block (light engine ) replacement light engine cost $1400 and labour $400, so i called back hitachi and they said they will provide light engine and will have to pay labour!....this is not right paying out of pocket for a tv less than 2 years old....I am not sure if the issue will resurface again...more likely ....Hitachi is supposed to issue a recall or atleast like sony did to cover all cost for there defective TV's....I will NEVER buy hitach again.

Hitach SUCKS.

Blue area near center of screen


Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with hitachi and start complaining, then keep complaining until they agree to pay for it. You may have to get the problem diagnosed by a pro before they agree to pay for it though.
