    we turn it on and the green on and off light just blinks on and off but the tv does not come on we hear the fan but no picture, we had moved it to another location when this started. the lamp looks good and is not too old. what do you think could cause this? how do I tell if the lamp has gone bad or could it be another problem.

Generally, projectors will not power up again until a set amount of time to allow the bulb to sufficiently cool. My Optoma cannot be restarted until a 2 minute cool-down period.

I am having the same problem and it is bigger than you think. You have up to 4 burned out fuses on your power supply (850, 851, 852 and possibly 860 but mine is fine). Not normal fuses either they are 125 watt 5 and 2 amp micro fuses located on the top middle of your power supply. Kind of a bother to fix I am working on mine now. you should also resolder all of the staples (at least 010 and 050), which are the small metal rods that go across the circut card in place of a component. Go here for more info.

IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

Still sounds like a lamp:

TV won’t turn on
• Press the TV button or ON/OFF button while remote is in TV mode and there’s a source of power to the outlet or outlet strip.
• Make sure the TV is plugged in.
• You might have tried to turn on the TV during the lamp cool-down. Wait a few moments and the picture will appear.
• Has the power light on the front of the TV been blinking for one minute? If so, the lamp may be dead. Refer to the Power indicator
is blinking or fl ashing
section below for more information.
• When you fi rst plug your TV into an outlet, the Power indicator on the front panel will light and blink for approximately 30 seconds
and then go off during the initialization of the TV. This happens only when power is reapplied to the TV. The TV can only be turned
on after the Power indicator goes off.
• Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in something else, such as a lamp.
• Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the
remote control solutions on page 84.
Remote Setup might be set to the wrong option. Press MENU/OK on the front panel. Select Connections, then Special Features, then
Remote Setup. Choose TV (default).
Power indicator is blinking or fl ashing
If the light blinks 5 times, pauses, and blinks again 5 times, the lamp is trying to turn on. If the TV doesn’t turn on after 5 minutes and
then the light blinks steadily for one minute, one of the following options is possible:
• Lamp door may be open.Face the back of the TV. Locate the door at the bottom of the TV and close it. Turn off the TV and turn
back on. The lamp should turn on.

You can easily replace the lamp yourself by following the lamp replacement instructions. If your TV is still covered by
the warranty, call 1-866-723-6486 to receive troubleshooting assistance and a lamp replacement.
• If your TV’s warranty has expired, call 1-800-338-0376 to purchase a lamp replacement.

To order the correct lamp, you’ll need to know your TV’s model number, serial number, and lamp type—this
information is listed on the Service Model Number sticker (example of the sticker is shown above). Face the back of
the TV. The sticker is located on the right side of the TV.

Hope this helps :)

TV auto shut off-power indicator light blinking-won't turn back on


You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
