Hello,

the projector will shut off when the lamp hour count reaches expected lamp life. It will restart only long enough to read the hour meter again then shut it's self off again. You can manually reset the hour meter to continue using the same lamp. Good luck.......

Does the Optoma HD20 DLP projector have a air filter? If it does, where is it located?


Hello

The Optoma HD20P doesn't have an air filter.
If you remove the covers you will find 2 cooling fans that get a build up of dust on the leading edges of the fan blades.
These can easily be cleaned with a small paint brush and a drinking straw to blow out the excess dust.
If you are having overheating problems, please view my post on replacing the heat sink compound on the image processor.

Cheers

Optoma hd20 fan shut down


I put this here because when I was experiencing the same issue I found there was very little info online for this topic. Optoma asked me $125 just to take a look at my out of warranty hd20 projector after I started getting the dreaded "fan failure" error message, I got this error mesage after replacing the bulb (its important to note that the bulb did explode in the unit so some of the debris may have lodged in the fan.) Optoma also kept saying stuff like motherboard issues and fan sensors on the phone. Everything I've read has said the repair price is so high on these issues that it is better to upgrade to a new projector so I resigned myself to doing that very thing. Then I ran up on this video and thought what the heck. So I took the plunge and popped the case off and sure enough the same little fan was stuck and covered with dust. I gently moved it with a screw driver and blew all the dust out of it. Plugged it back in and I'm experiencing glorious 135" hd once again.

I just got a new Optoma HD20 and only after 1day of use it is not showing HDMI signal, although it is showing VGA signal. Why is this?


Hi miracles4all: I solved HDMI signal issue in my Optoma HD20. In my case it was the lack of contact between the HDMI cable plug male ending and the Optoma HD20 HDMI female port. My 35ft cable plug male HDMI ending was not completely "seating" in the Optoma HD20 HDMI female port. I solved the problem by purchasing a HDMI female to female coupler and adding a 3ft HDMI cable that had a slim male ending. This 3ft HDMI extension cable made better contact to the Optoma HDMI port and the projector was immediately able to detect HDMI signal. Hope this helps you... kaufmanekpr

I have an optoma HD20 and it connects using a 1.5m HDMI but as soon as i try a 10m HDMI connection (even with a booster it does not connect) any suggestions welcomed?


Hi kgomer782 I have similar issue. My optoma hd20 signal connection with a 3/6ft hdmi cable is perfect. However, no signal is detected when connected to a 35ft hdmi 1.4 cable. The 35ft cable is indeed working becuase I tested it succesfully when connected to a 1080p HDTV. Did you received any solution to your problem? I wonder if it has anything to do with the HD20 design of the "debossed" hdmi ports that prevents the cable plug from getting completely "seated" in the port? My 35ft cable has a flat square male ending however, the 3/6ft cables have slim male ending that seems to accomodate perfectly in the Optoma's hdmi port design...kaufmanekpr
