Light engine part # 3141VSN180F
Digital Board part # 6871VSMV99B

No service bulletins on this at all....
I think it's best you contact Zenith about this symptom. I had a Samsung
recently that looked like the Digital board was at fault, customer added
more symptoms upon return with board.

Those extra symptoms alerted the Samsung tech to what was really bad.....the
DMD module.
Upside down picture will do it every time....after I had requested the
customer try the menu and channel up/down button when his TV goes
black.......DMD loads down the data line

You may want to try the menu or changing channels after it fails and see if
there are any other symptoms that can help in the diagnosis.

I know this is an LCD, not a DLP, but the fact remains that the digital
board and the LCD engine both use the Data/Clock lines.....you could have a
crappy tuner for all we know.

> Haven't seen this yet but customer says the pic turns greenish yellow with
a pulsating affect. Then goes black. Sound remains. They turn the set off
and on sometimes more than once to bring picture back to normal. Is very
intermittent with no pattern. May be days before it acts up again. Anyone
seen this or anything close?  Light eng.?
