I have a Samsung DLP 56" TV (Model Code--HL56A650C1FXZA), that turns on and off by itself.
I've removed the back panel, and vacuumed and compressed aired off everything I could; including lamp removal and reinstall. I set the little blue switch under the lamp cover, as required, during cover replacement. All moving parts (fan wheels) are working. Everything starts up and runs for a couple of seconds, and then the cycles continue. Never stays on for any extented time.
What might cause the sets continuous on/off trouble???
HELP!!! I'm lost here.
Thanks much, in advance!!!
