Sharp DLP RPTV model 56dr650 , making a loud noise and has horizontal lines across screen, what is the problem? Answered

My Shrap DLP rptv is making a loud sort of grinding sound like it needs some lubricant. I recently replace the lamp and clean the color wheel. Could it be due the fact that I didn't tighten the screws tight enough? if not, what could it be?

Are you sure the color wheel isn't rubbing against anything?
