I have an RCA HDTV rear projection tv model # HD56. It had been left on for approximately one week and the picture is gone. I have audio but the screen is black. Looks like something burnt out from being on for a week. What could it possibly be and is this an expensive fix?
A set with no picture could be a lot of differant things. It could be a vertical sweep problem, a horizontal sweep problem,a viseo circuit/processor problemor if its a micro display type ,could be a bulb or bulb circuit went bad. If you have no TV repair or solid state repair experience, please call a trained tech out to assist you with this repair. as to the cost? It really is all going to depend on what and where the problem is. Sorry I could not be of more assistance to you. Please let us know how you made out with this repair. Good Luck
