It sounds as though your light chamber is collapsing. This is caused by intense heat from the lamp inside the light engine causing the glue to melt that holds several tiny mirrors in a pyramid shape. This is a very intricate repair but can be performed relatively cheap compared to the replacement cost of entire light engine if you find the right service person. Look for an authorized service center or at least someone who knows what the expression light chamber collapse means. The small group of mirrors is located right behind the color wheel and requires the lamp, ballast, color wheel and housing to be removed in order to be replaced. Caution should be used when replacing this fragile compenent.

Black bar on dlp tv.how do I fix this?


Sounds like a connection problem between board and DLP chip. The BGA connection which connects the DLP chip to the board, or the flex connector may be bad, causing the row and column section to not activate the micro-mirrors on the DLP chip. Not an easy fix. Regards.

Large black bar to the left of screen


When replacing the light tunnel, the new one must be installed exactly as the old one came out. This can only be done by marking the screws and backing them our exactly 3 or 4 revolutions and then tightening the new one the exact same revolutions. When looking into the old tunnel you should have been able to see the mirror that came unglued to ensure that was the problem. The problem now can be corrected by loosening the screws on the dmd bd and manually adusting the dmd position in association of how it hits the dlp chip.

Light engine issue I would say, is it somewhat transparrent? if totally black might be something else but more than likely will be a light path issue inside the light engine.
