99% of the time these symptoms are caused by a ballast (if you have a new lamp in your tv).
If your lamp has been in your tv for around a year or it seems burnt, fogged or damaged, this might eb eindicating you need a new lamp.
hope this helps!

I have a 2 year old Samsung DLP 56" TV (Model Code--HL56A650C1FXZA), that turns on and off by itself. It cycles every couple of seconds, but never stays on long enough to even get an idea where the trouble may be.

I've removed the back panel, and vacuumed , and air blown off everything I could; including removing and cleaning the lamp. All moving parts (fans and wheels) are operating; I set the little blue switch under the lamp cover, as required, during cover replacement.

What might cause the sets continuous on/off trouble???

HELP!!! I'm lost here.

Thanks much, in advance!!!
