I have a Samsung HLS5687W XAA DLP TV made in 2006. This set will not stay on. I push the power button on the TV. The Map light flashes brightly and the adjacent light flashes dimly. The projection bulb is on. The flashes last about 15 sec followed by a strange tone and then the light shuts off. What could be wrong?
I have cleaned the fans and they are turning. The bulb stays on. SO I believe the bulb and ballast are good. I held down the door switch. Nothing helps so far.
I hope you don't 'chuck it' since it DOES sound like an interlock. I can't help but would ask you to post back if / when you get it fixed so others will know. You've done some of the obvious stuff, which is pretty much all I'd do.
I have a HLS5686WX/XAA and it won't stay on. it will shut off at different times. sometimes it will stay on for an extended time, other times it will continue to shut down at different intervals. Need help.
