I have an optoma hd65 projector. A while ago, the projector would not boot up anymore, the fans run, the green light blinks, and about 30 seconds later, the lamp led light will turn solid red and stay that way. I purchased a new bulb, installed it today, and the same exact thing happens. Can anyone please help me???


I cleaned out all of the vents which were not very dusty. Also, previously I had been using the original power cord. I couldn't find that one and used a computer power cord. Could that have anything to do with it? I wouldn't think so being as it did the same thing with the original power cord but who knows.

I have tried doing research on this searching the web and have found a lot of people having the same problem, but have not found a solution.


Any help is much appreciated. Thank you.

Sarcasm is always appreciated. Especially when people don't have a good answer to your question. It'll take you far, I promise you.

Why not give ACER a call?

Really, about the only thing I could think of is that you need to reset the lamp timer, which I have no idea how to do.

Well if anyone has ever encountered this problem, I found the solution. The problem was the lamp driver. Replaced the lamp driver, and the projector works now.

I purchased the lamp driver direct from Optoma for $111 shipped. Installation is fairly easy after you open up the projector. There are multiple screws on the bottom of the unit. As well as three tiny screws, one on either side, and one on the back. Make sure you remove all of these. After you do this, press down on the top and slide the top cover towards the lens and it will come off. I recommend removing the three screws on the top cover that connect the controls to the main board. The lamp driver is located on the side of the projector. I took pictures along the way to establish the orientation of everything. Once you remove the lamp driver housing, its fairly easy to remove the old lamp driver and install the new one.

I removed my email address from the previous post as it has been some time since I replaced my driver and I'm a bit foggy on how to do it now. I'm told the lamp driver is actually cheaper then when I purchased it. Hope my information helped and you have fixed your projector, mine is still running strong!
