I had a similar situation, but we fixed it.  I can't exactly tell you why it worked nor whether or not it will for you.  Here's the deal.  
First, take your lamp out and re-seat it.  This is one of the easiest ways to get a projector not to power up.
In our case, the thing would fire up, show us the Optoma logo, the blue screen, and then within about 15 seconds, it shut down, lamp fail light came on, and only a hard power reset would let us try again.  The bulb was good; after all, it came on, right?
So, we kept playing this game of power up, fail, unplug, replug.  I gave up and went to do something else.  I came back to the projector, needing it to let me see a screen to configure (weird I know, but that's how it was).  Anyhow, at this point, the projector stayed on, no problems.  So, I kept it running through the night with a kitchen timer on.  After 5 1/2 hours without failure, we knew we were set.  
The point?  If it's powering up and showing picture for even a brief period, try cycling it several times.  However, if it's overheating or showing any other signs of distress, you may make it worse using my approach.  I think we may have just been lucky or the projector gnomes came in the night.

What's your problem?My hd70 stopped working: when i go to turn it on you can hear the fan spin up but where as in the past there is a brief delay and then the bulb lights up, there is now a long pause


It will be worthwhile to test the lamp on another unit or at a test center to confirm as the fault seems to represent a faulty lamp. If this is confirmed then the we can proceed to access the voltage on the lamp , if so the trip is due to low delivery from the power supply section and so it trips on loading of the lamp.

Used my OPTOMA HD70 ABOUT 2years now -and had to replace the lamp i unplugged it and when turning it back on to work - it does not start , it`s dead the green led lamp does not flicker , does not work...


There is a switch on the side where you insert the lamp, it's black with a metal contact. If, when the lamp cover is replaced, it does not "activate" this switch for some reason (i.e. it is loose or perhaps bent) then the projector will not power at all.

Just remove the lamp and take a look at the switch for possible damage incurred from when you replaced the lamp.

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..
