It should either be secured with screws or plastic clips that need to be pressed in to release the board

When I turned the tv off last night the picture was fine, but this morning when we turned it on this morning, the picture is very dark and mostly blue. 51F59A, purchased in Dec 2006.\r\n Thanks for any...


Hi,

If you turn the tv off for about 1020 seconds, turn it back on and see if you have a clear picture, if not it sound like a power supply problem in the tv. but if that did not solve the problem, the picture board on your tv is now malfunctioning or as gone bad, it means the picture board of your tv has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your tv to solve the problem.

Samsung HL61A750 61 Inch 1080P Led Powered DLP HDTV will not stay on. It can be turned on, but 15 or 20 seconds go by and it goes/tunrs off. Everytime.


It sounds like the lamp bulb, I had the same problem and I took the bulb unit out of the back, cleaned it out really good and replaced it, it works fine now and I didn't have to buy a new bulb unit for about $200.00. Good luck.

Sounds like you are developing a short somewhere. Replace the power board, or have a tech trace the problem on the power board and repair it.

MITSU 65513 BLINKING GREEN LIGHT WONT POWER UP


Good Day, xbossux;
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.

Ballast Verification Process
1. Short out door switch (SP001)
2. Apply AC power and wait till DM module boots
3. Press power switch and observe spark gap on ballast
4. If spark gap arcs, suspect Lamp. If color wheel starts but ballast won’t strike
lamp, go to next step.
5. Measure BP252 on AC IN CBA for +300Vdc. If missing check door switch, cable
from AC IN CBA to switch and AC IN PCB. If correct go to next step.
6. Monitor pin 2 of BT251 for Ballast ON command from Light Engine. If present
suspect Ballast. If missing suspect Light Engine. Pin 5 of BT251 starts at 3.3V
after power switch is pressed and drops to .18V when the Light Engine sends the
start command. No change on pin 5 indicates Light Engine is suspect, change
on pin 5 with no ballast start, ballast is suspect.

Note: Lamp may arc but not start. Pin 5 of BT251 is "LAMP LIT" and goes to 1.48V
when lamp is lit. If ballast strikes lamp but lamp won’t stay lit, suspect Lamp.

The capacitors are solderd into the circuit board so you have to melt the solder with a solder Iron to remove the legs of the capacitors from the circuit. Then you have to install the new capacitors in the same pin holes and resolder the legs. Be sure that the negative side of the capacitor goes back in the correct hole like the old one was.

The power supply is what provides all the standbye voltages that get routed to the various other boards. The capacitors have to be unsolderd and the replacements solderd in.
