Can you hear the color wheel? If so--is it to loud. Set might not be able
to sync up with color wheel thereby causing shutdown. Replace light engine?
Samsung won't fire at all (light) if color wheel don't sync up.

> Hello all,
> Repaired this set a month ago and it's back to haunt me again. This time
it's come in dead with standby voltages ok. Changed the DM2 board and the
set fires up, but shuts down after ~ 20 seconds, after 20-30 seconds it
starts up again runs for about ~20 seconds and keeps repeating this pattern.
The fans don't even attempt to turn, so I suspect this is the problem. I
just can't seem to locate the fans on the cd schematic so I can trace where
the problem is. Either I'm going blind or can this be a board replacement
problem?
