Turning on...and does not turn on...unplugged for over 1 minute...didnt help...eventually all lights turn on, all three
Different model, but this is from samsung service manual:
1. If the 3 LED indicators flicker from the time the set is
turned on, it means:
1) The CN106 connector on the DMD board is not inserted
properly.
2) The MDR cable that connects the DIGITAL board to the
DMD board is not connected properly.
3) If the lamp does not turn on even after turning it on three
times, by powering off/on 15 second intervals:
! The B+ 380V power is not supplied to the ballast
(The cable is not connected properly between the power
and the ballast.)
@ The cable connected to the CN110 terminal on the
DMD board and the CN2 terminal on the ballast is shortcircuited
or not connected.
# The lamp does not turn on because 5V has not been
supplied to blue pin #1 on the CN2 terminal of the
ballast.
$ 5V is supplied to the CN2 terminal on the ballast but the
lamp does not turn on because the ballast has a failure.
(If the lamp is replaced and 5V is supplied normally to
the CN2 terminal, suspect a ballast failure if the lamp still
does not turn on.)
% The ballast is normal but the lamp doest not turn on.
(When 5V is supplied to CN2 and 385V to CN1, but the
lamp does not turn on, try replacing the lamp. If it turns
on, that means it was a lamp failure.)
4) The color wheel engaged to the engine does not operate,
or the connector which indicates the operation of the
color wheel is not connected properly, and therefore
does not allow the lamp to turn on. The cause can be
determined when the set still does not turn on after
attempting to turn it on three times.
5) Another digital board or the DMD board has a failure.
Conclusively, if the three LED indicators flicker, first
check the above five items, then check the various
connector connections, and then suspect a failure of the
lamp or the ballast.
First thing to check is the bulb. On the back of the set is a hatch with four black screws. There is a TT symbol on that hatch, open it and you'll see the black lamp housing over the ballast circuit board. Remove the silver screw on the left of the housing and pull the aparatus straight out. It may stick a little, don't be afraid to give it a tug or two. Check the bulb, the part of the filament that burns is inside the glass tube that is near the base of the bulb bowl. If it looks broken or burned. Replace the bulb. Ebay sells them for about $100 or less. I've never had a problem with OSRAM vs Phillps, so whichever. Phillips is better but OSRAM does work too.
Sometimes you buy the bulb with the housing sometimes not. Its pretty easy to replace the bulb. You-tube it. Reverse the dismantle and see if it comes on. If not, we move onto the color wheel and ballast. Email me if this doesn't fix your problem and I'll help you move onto the next step. [email protected]
Good luck.
The on and off problem is the DMD board. This is a factory defect whether samsung will admit it or not. The DMD board is on the light engine and replacing the entire engine as a whole is typically the only way to get a hold of a new DMD board. Consider $300-$400 (ebay) for a new engine a decent price. Samsung will also sell you the engine directly. Which means it comes with a warranty. Email me if I can be of further help.

Sounds like mine. It makes the same sound as it did before when you turn it on and it sounds like it wants to turn on, but nothing and eventually the lights blink. Before this happened though, there was like a popping sound and the tv turned off.
Sounds like what I have. it makes all the sounds that it usually makes when I push the on button, but nothing. Before this happened, there was a popping sound and the tv turned off.
Sounds just like mine, did you get it fixed?
My Samsung DLP HLP4663w have the same problem, 3 LED blinking.
I replaced DLP lamp, no help
I took my new DLP lamp and ballet and tested it on other Samsung DLP tv, both work fines.
I removed DLP lamp, and back cover, and forced enable Back cover switch, I used a flash light to see thru DLP lamp hole, I can see that Color wheel spin nicely.
Is it the only problem DMD board? Too expensive to replace whole light enginee. HOw can I test DMD board? It is possible to fix it at component level?
