Optoma H27 Projector will no longer power up after bulb change

I purchased an Optoma H27 projector three years ago. Recently, the bulb life warning message has appeared when turned on. Yesterday afternoon, the projector turned itself off and was unresponsive while the kids were watching a movie. There were no blinking lights on the housing to indicate temp or bulb failure. Later in the evening, the stand-by light was flashing again. I turned on the power and the picture came back for less than an hour when it went into total power off again. I assumed that these events were related to the bulb reaching the end of its useful life. I followed the instructions to replace the bulb with an OEM replacement bulb.

Problem is the projector will not power up with the new bulb or with the old bulb put back in. I can not find any type of reset button or fuse. All I can find is a proximity switch that the bulb cover actuates when installed. I cycled the switch a few times in case this component was not making a good connection. This did not change the outcome.

Is there anything else I can do to troubleshoot and restore the projector to proper operation?

    I have a very similar problem, i get no power when i turn it on. No Flashing lights at all. Wierd thing is it is always isolated from power when not in use. Twice this has happened and twice power has come back at random times and worked fine? The bulb has sone next to no use over the 3 years ive had, maybe 100 to 200 hours.

The only way is to reset the bulb hours counter. There are instructions on how to do this with the replacement bulb. Please note that this procedure will reset the counter to zero(0). You should kee track of the actual hours on the bulb so you don't get surprized during a presentation.

SOURCE: on my optoma H77 I am replacing a burnt out bulb

clean out the projector with canned air to get rid of the dust that could be causing it to overheat. also make sure the fans are spinning. if it still blinks, replace the temp sensor. if it overheats alot, the sensor will wear out from excessive heat.

either the lamp has/is going to expire, or the ballast is bad. if the lamp has bulges or black spots on the inside, replace the lamp and clean out your projector with canned air. too much dust keeps in the heat and makes a 2000 hour lamp go in 1100 hours.

SOURCE: 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.

The color wheel sensor needs good cleaning. an optical lens cleaning liquid might help. also clean the fans and vents if you open it. I had to remove the sensor and clean. then it worked.

Bulb blows on gt700


Possibly a bad ballast or power supply going to it causing it to either kill the bulb or your old bulb may still be good. Did you rest the counter in the menu for the bulb life after replacing?

My projector's power light is red, but when I click power it won't turn to green (on)


The likeliest problem here may be a burned out or failed projector bulb. Most projectors will fail to power up at all when if the bulb is out. The HD20 user manual does not specify a red light as an error indication option however, generally amber.
User manual .pdf is located here (takes a bit to download for it's size), Projector Status Indicator instructions are located on page 40.
Here on the product page itself, an email to Optima support may be warranted given the red instead of amber error light.
If you had any messages recently indicating your bulb life was nearing it's end, again, this would be my first guess. Certain models of projectors do have a tendency of blowing through bulbs even before any warning message comes up. I had an experience with a certain brand/model that for the last 3 replacements has given only about 1/4 of the stated bulb life, so unfortunately it does happen.

How do I find the remaining bulb life for the Sanyo PLC SE-20


There is not a set time for bulb life. The projector will have a timer built in to tell you how many hours it's been running. I've had projectors that I've reset the warning twice before I've noticed any performance issues with the bulb. That particular bulb has a life of approx 2000 hrs, so go through the menu on your projector and find the "lamp timer" or something similar to that and do some simple math. :)

OK, found the solution on the net, you have to use the buttons on the projector instead of the remote to access the menu item.
