Sounds like bulb to me best way to check is take it to a service centere and they will use a replacement or test bulb to find out for you , it may not be your bulb it may be your ballast circuit . ... regards Vortash

What does it mean when all three lights, standby, temp and lamp, remain solid on Optoma HD72?


I suggest you go to eserviceinfo and search for the manual on this unit, sometimes this indicates a filter door open or bulb carrier door not closed. But to be honest without seeing the manual ?, however you didn't say if the unit was working despite the lights or not. Check the doors to all compartments and see if they are closed properly, other than this advice I suggest you seek an engineer to check it out

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

Optoma HD 70 turns on with lamp and temo soiled lights


Asher fadida and alll,

The issue:
solid red error light?
HD70 "die's" after few min with strage noise?
flickers different colors before complete self shutdown?

well try this....

Before replacing your bulb, fan or any other component try first cleaning your optoma realy good!! HD70 doesnt comes with any kind of filter so you can imagine the amound of dust can be.
The most importent thing is to blow away any dust from your color wheel + the sensor attached to it .

for farther troubleshoting clean your fan's.
there are 2 fan's insinde the HD70.

probably the most problems will be solved by cleening the color wheel!!
if the problem is not solved ,chack the lemp and the fans if they work properlly.

For fan replacing:
Fan Part number: GM1207PKVX-A

Optoma HD72 flashes red and green. I changed the lamp but the problem wasn't resolved. Any input would be greatly appreciated.! Greg


I had the same problem with flashing colors after playing for awhile. The following helped:
1. turn off bright mode from menu.
2. keeping the back side of the projector flat. I had it raised up about 3" on the backside before, not sure why but it worked fine when flat.
Hope these help you also.

Optoma HD72 displays white circles when the picture is dark


Have your projector professionally cleaned. It is dust in the inside optics. You should not attempt unless you are very skilled. if you are going to do this yourself have a lot of compressed air on hand.
