Question about Optoma Office Equipment & Supplies

1 Answer

We have an Optima EP 719 projector. The bulb would not light after I plugged it in and pushed the on switch. The power switch illuminated and the fan came on for about 30 seconds. Then, the lamp indicator flashed red, the fan shut off and the projector went back to standby mode. I replaced the lamp unit and still have the same problem.

If you hear a high-pitched whir, you have a ballast problem. if you don't hear it, you have a colorwheel problem.

Check poewer connection
Check if fan filder is dirty ( if it is just hoover it out)
If "lamp" light on top of the projector blinks or stays lit - lamp probably faulty

possibly the bulb is blown this is very expensive to fix most of the time.... maybe water damage but since it all turns on and apears to work then this is less likely then bulb blown..... if the bulb is definatly not blown you could take it apart and put a hair dryer on it from a distance... do not heat the boards up much just enough to get rid of any moisture.... best of luck and i hope you can get it going in time....

After changing the bulb image will not come on and solid orange light appears


Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

I have an optima EP 739 projector and I just replaced a bulb in it but it does not come on just green light whats up Any input would be appreciated


if the fans come on and the lamp doesn't, it's the ballast or the colorwheel. if no fans either, it's the power supply. also, did you reset the lamp timer?

High temp light on when powering up


Remove the screws and check out the fan's working state.
EP759 have one big 92mm fan for the lamp, and three small, near 40mm, fan's for the optics.

Power of the bulb is very high, so just 1 broken fan can make that situation.

You can test the power source if you are getting any power input from the power cord itself. Plug in your power cord and use an eletronic meter on the other end to see if you are getting the proper voltage (110/120) reading. If not, then the power cable is bad in itself. IF you are getting power from your cord, it could also be a fuse inside the Optoma and/or where the power plug on the Optoma meets the actual power source is out of alignment or may also be not making the proper contact to the main circuit board on the Optoma. Hope it helps....JGUAM
