New bulb not working

I have an optoma 738 and i powered it up and it tried to turn on the lamp ( i could hear it )
after 3 tries the lamp light came on, so i assumed the bulb was burned out so i ordered a new one.
got it and put it in and the same thing happened.
i removed the bulb and inside i noticed that inside the light socket there is a tan colored wall near the lens to the left it looks like a hole has burned throught it.
could this be the problem and how do i fix it?

ITS NOT A BULB ISSUE IT IS A TRANSISTOR THAT MEASURES HEAT TO TELL THE FAN WHAT TEMP. TO KEEP THE SYSTEM AT AND IT IS BURNED OUT AND YOU WILL HAVE TO TAKE IT TO A DEALER AND SEE IF IT IS WORTH FIXING.

Why would my projector refuse to start with a seemingly intact light bulb?


If you only have 300 hours on it it should still be under warranty. Before doing something to void that I would check with Optoma techs.

Optoma hd65 projector new bulb wont turn on...cant reset timer!


I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.

Infocus x2, the bulb melts the small square lens even w/ fan on


either the ballast is bad and is sending too much current to the lamp, the lamps are a cheap knockoff, the thermal fuse is altered, and/or one of the fans aren't working.

High temp light on when powering up


Remove the screws and check out the fan's working state.
EP759 have one big 92mm fan for the lamp, and three small, near 40mm, fan's for the optics.

Power of the bulb is very high, so just 1 broken fan can make that situation.

You can test the power source if you are getting any power input from the power cord itself. Plug in your power cord and use an eletronic meter on the other end to see if you are getting the proper voltage (110/120) reading. If not, then the power cable is bad in itself. IF you are getting power from your cord, it could also be a fuse inside the Optoma and/or where the power plug on the Optoma meets the actual power source is out of alignment or may also be not making the proper contact to the main circuit board on the Optoma. Hope it helps....JGUAM
