SOURCE: dvd10 optoma projector makes a loud noise

Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.

I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

There is a stuffed 10v 3300uf capacitor on the power board. You need to replace it.
Bellow you can check in the picture where the capacitor is located.

Notice that in this picture I have already took the bad capacitor out and replaced with two small cords to reach the bottom and test the new capacitor.
To reach this place is not fast, several layers of plastic and metal must be removed, but is not a hard task to take the capacitor out and replace it for another.
It works just great! Now it is back on track with awesome image.

By what you have told me, the lamp possibly may have blown, so check if the product is still under warranty as you may be able to claim another lamp at no cost what-so-ever! It is however a definite code to tell you something is wrong! Hope this helps ;) ZKhan

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.

Optoma Projector power LED is blinking green,funs are not working, lamp not function, how can i solve this problem


i'd say power supply issue, but the led is blinking green. this means that it thinks it's in warmup/standby mode. but if nothing's running, the main board might be bad and needs to be replaced.
