Television and Home Theater

Ok this afternoon, my mother in law tried to turn off the tv and it refused to turn off and started making a loud noise. So I had my wife unplug the tv and everything got quite. Problem now is everything is still quite... I plugged it back in and it refuses to power on at all... I hit the power button nothing, hit the remote power nothing, hit the reset nothing.....

I took apart light engine and cleaned RGB lens covers that had the dust build up . But when i put it back together the colors were out of alignment . (The picture no longer has the blue blocthes ) I should not have taken the lens off there mount and should have cleaned without removing them individually . Tried to align them with the screws but it is not working well ( very sensitive ) . My question is i noticed the service manual is availible on this site and i have downloaded but can the colors be aligned like it is done on a rear projection set ? Thanks for any info , James
