    SAME PROBLEM, SOON AS IT STARTS TO LOOK FOR SIGNAL SOURCE THE LAMP TURNS OFF

  • Anonymous Apr 13, 2009

    my father and I both own the Optoma HD72 and experienced the same problem. He had this issue about 2 months ago and had to send the projector to Optoma for service. They told him it was due to a component inside the machine experiencing a short. His unit was out of warranty, so it cost $350 to have repaired. I just began experiencing this problem in the last couple days. My machine is still under warranty, so I am hoping that they will repair it free of charge.

AS regretable as this sounds component failiure was my first thought .. It's not the bulb temp sensor as the fan is opperating and that usually cuts all power .
You may find that as you have a bulb ( usually worth more than the units they reside in ) rather than a repair another unit of Ebay would be a safer and more economic conclusion ... Regards Vortash

Optoma lamp led flashing


the are a few reasons for this but the most two common ones are the intermitant lamp failure or colour wheel tracking rotation sensor when you startup the projector the lamp should drive half brightness approx then you should hear the colour wheel drive if it is at this point the projector goes off and restarts the chances are it is dust on the colour wheel sensor.Rmove sensor this has three wires going to it supply and pulse wire it is mounted on a small pcb board with one screw remove the screw and board complete with sensor and clean the sensor with a cotton bud dipped in spirits then wipe over with clean cotton bud.This usually solves the problem.

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 H31 - Turns itself off !


sounds like the projector lamp to me. the rated hours are always up to the published hours and never "this is what you will achieve." I would suggest getting a lamp as you will need one shortly by the sounds of it. In many cases the projector does this as it is programmed to protect itself from the lamp shattering inside the projector. Let me know if you would like a quotation for a lamp as we ship internationally. Regards Kevin Andreassend. http://www.iceav.co.nz iceavtech@gmail.com +64-9-4142348

The optoma hd72 projector lamp goes out after 30 seconds.. the big game is this weekend... what can I do?


I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit.

I've had the same problem with my projector three times (usually whenever there's a sports championship). You just need to call optoma, get an RMA number, and ship it to them. Theoretically they'll fix it under warranty and send it back free.

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.
