It could be a bulb problem. Projector bulbs have an estimated number of hour (in thousands) life span. If you think it had served you that long, then fair enough and try to buy it a new bulb.
Another cause is inconsistent power flow. Please use a Surge Protector or an AVR and plug your projector there to stabilize the power flow. Please do this first before attempting to buy a new bulb

My optoma hd70 projector which is 4 years hold has worked perfectly. However when I switch it on it works for a few minutes, then the screen turns various colours, it makes a funny noice and then switches...


The color wheel sensor needs good cleaning. an optical lens cleaning liquid might help. also clean the fans and vents if you open it. I had to remove the sensor and clean. then it worked.

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

Hi, I have an Optoma Hd70 and it keeps turning off after about a 1 min and the temperature indication is blinking red. Is there an airfilter I can clean or something?


Sounds like there is a overheat sensor failed in this unit in the lamp balast sure a cloaged filter could heat the unit as well so yeah check that..
