Question about Mitsubishi WD-73C9 73" DLP TV
Did u touch the lens or bulbs when u cleaned it? It could be a color wheel problem but i think u should try to reset light tunnel. Did it give you any warning? or did it just all of sudden go dim. I gave u a link to a trusted YOUTUBE tech.. i use his work all the time.
See if any blink codes come up if u disconnect a bulb..good luck
