SOURCE: EP 757 Intermittent powering down

Pls check if the lamp is not so old that is giving the same problem. If lamp is almost new, then you can have a check with the Ballast unit card and then the loose connection in the Power supply or may be overheating and tripping.

SOURCE: color problems

i don't know if this will work but..... I have an Optoma h27 and we were having problems with the color and ours is mounted on the ceiling in inverted also; and after two years we started having color problems, come to find out that on the menu there is a option for high altitude and that had been turned to the "off" position (probably by our kids resetting all the options and not turning this one back on)..... after taking it to a tech that cleaned it for $97.00 and said there was no problems he could find, we played around with the remote/menu and came across this high altitude option and when we saw it was on the "off" position, we put it to the "on" position and another fan inside the projector came on and that helps to keep the inside of the projector cool at all time and helps from the color becoming weird..... Try this on yours and hopefully that will solve your problem.

SOURCE: Program Optoma EP-739 remote to Bell Express Vue 3100 remote

1 - Hold the clear tv buttom until all 4 light flash red
2- Press the red tv buttom
3- Press the amount of time needed on the up cursor ( around select buttom) until your tv shut down
4-When the tv goes off press the search buttom ( at the end on the right side )
5-Press record

Then u can use the red tv buttom to control ur tv and u can control the volume on satelitte mode without going back to tv mode , if u press too much time while searching the code and the tv wont light back , do the same thing but instead pressing the up cursor press the down one to go back on the code it will be faster .

SOURCE: Optoma H56 - turns off just after start up.

It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.

i'd say power supply issue, but the led is blinking green. this means that it thinks it's in warmup/standby mode. but if nothing's running, the main board might be bad and needs to be replaced.

Why would my projector refuse to start with a seemingly intact light bulb?


If you only have 300 hours on it it should still be under warranty. Before doing something to void that I would check with Optoma techs.

Optoma gt700 is all green after replacing color wheel


we mainly retail or distribute color wheel, light tunnel ect sparet parts for projector or TV, so we have experience on that problem you faced.

perhaps you ordered a compatible color wheel,but it is not big trouble. compared with your old wheel, you will find a black tape, just make it as the same position as your old wheel, it will be ok.

I have sanyo projector model PDG-DSU20E. Few white spots appeared on the right side of the screen. Gradually the spots has filled the right side about 1 feet is width till bottom of the screen. Now few...


1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

Have a good day!

Optoma ep 1690, the on/standby led is flashing green but when I try to turn it on the temp and lamp led's flash twice and nothing happens, the on/standby continues to flash green.


The projector lamp life may have exceeded its safe limit, check your instruction manual, sometimes you have to hold the on or off button for 10 seconds to reset this. All manufacturers are different but that may be the problem.

Here is a copy of the manual, I havn't read it, my solution is from experience of other projectors.

Good luck

I my projector is new one used for 4 hrs, when i try to turn it on it just has a blinking green light. Please help Solve It! .


The blinking green light means the unit is either Powering On (Warming Up) or Powering Off (Cooling Down).

Powering On the Projector
1. Remove the lens cap.
2. Securely connect the power cord and signal cable. When connected, the ON/STANDBY LED will turn Amber.
3. Turn on the lamp by pressing " " button either on the top of the projector or on the remote. The ON/STANDBY LED will now turn Green. The startup screen will display in approximately 10 seconds. The first time you use the projector, you can select your preferred language from quick menu after the startup screen displays.
4. Turn on and connect the source that you want to display on the screen (computer, notebook, video player, etc). The projector will detect the source automatically. If not, push menu button and go to "SETUP". Make sure that the "Source Lock" has been set to "Off". If you connect multiple sources at the same time, press the "SOURCE" button on the control panel or direct source keys on the remote control to switch between inputs.

If you are still unable to get the unit to turn on, try unplugging it for 10 minutes and plugging it back in. If it still ceases to work, contact Optoma here: http://www.optomausa.com/rma_policy.asp

Optoma EP739 Projector Overheating


Set the projector to "high altitude mode." It will be noisier, but won't overheat. I wonder whether using one of those $10-$20 laptop coolers underneath it might be a quieter solution.
