Replaced Everything-Still No TV

[icharus22]

I have a 50" DLP Hl-S5086WX/XAA. A couple weeks ago the tv just turned off. I started with the lamp, then the color wheel, and yesterday the ballast. Replacing them has not brought the tv back. When I turn the tv on it chimes like it's starting, and after about ten seconds I hear a click and it turns off. The fans are all blowing, there is a green led light on inside.
I've tried resetting the door trigger, I've tried smacking the left side of the tv, I have no idea what else to try. Any ideas?

Not sure if you tried this already but ive read something about a Reset. Only requires unplugging set completely for 4 hours then plug back in. Sorry if its been done already and anyone feel free to correct me if im wrong.

Good Luck.
