    Just the power light comes on yellow, no opc light comes on. Then the power light flashes green with no picture and it is very difficult to power off again, have to hold in on the power switch.

Multiple issue,power light flashes


Sounds like first loose connection on circuit board. I would first look around the relay this is what clicks. Then also the low voltage transformers. These problems are always concerns when set is moved or bumped hard. Try this first. Or it could be a heated issue.

Power clicks on and red power light flashes but no picture


The problem might come from the fuse inside was blow out. if you have a multimeter then open the rear cover. The fuse lays near the power cord. Take it out and use Ohm meter to check it connectivity. If it is no connectivity meaning the fuse was blow out. Replace a new one with the same value (Ampere and Voltage). If it does have connectivity, the problem needs technician to find out as it relates to many parts on the circuit board.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
