Optoma ep795 projector won't power up after lamp replacement

Posted by on

  • Anonymous Apr 23, 2009

    I have the same problem with my HD640. I spoke with Optoma Canada and they said there's probably a manual reset that needs to be performed. I asked them for instructions on how to do it because I'd rather not send it in if it's something I can do. I haven't heard back from them yet (it's only been a day).

    Does anyone know how to do this?

    After the lamp burn out, it still has the power. Then, I removed the burnout lamp from the case so that I can see what looks like with a burnout lamp. Then, I put it back but never got power on again.

Is the bulb cover seated correctly? It disables the power if it isn't.

I have an Optoma DS303 projector. It stopped working. We replaced the lamp and it worked for about 3 hours and then when we tried to turn it on again, it won't fire up. Sometimes if I hold down the...


Check the voltage at the lamp input from the ballast after connecting projector to mains supply. (Warning: Do not switch on the projector while checking the voltage. It will damage your multimeter) The lamp connection shall be removed. If the voltage is around 60 to 80 volts AC, then your ballast is OK. Check for fragments inside the lamp.

My Optoma HD72 projector operates for about 1 minute and then shuts off. I kept my old bulb around "just in case", I've replaced the bulb with the old one and have the same problem.


The problem is not over-heating. The Optoma HD72 has a known problem that Optoma won't advertise. The lamp driver is faulty. They simply have to replace the lamp driver. I purchased a spare lamp with my original purchase. I had the exact same experience as you at around 1200 hours on the lamp in ECO mode. I used the spare lamp. Same thing happened at about 1200 hours. I had a friend at Optoma. he confided to me the problem. I sent it in and they replaced the lamp driver at no charge. I got another 800 hours out of the first lamp and am now using my second lamp and have about 600 hours on it. The pic quality is so good with this projector (used Digital Video Essentials to calibrate) that I'll just order a bare lamp or two and use the existing lamp housings when I need a new bulb.
