Question about Optoma HD80 Projector

Open Question

Great picture via DVI, 'interference' on picture via HDMI

I am having problems with my Optoma HD80 projector. I get a perfect picture when I input my Sony PS3, HUMAX FOXSAT HDR or Pioneer BDP-LX71 Blu-ray into the HD80 using the DVI input. I get a 'noisy' picture when I input any of the above using the HDMI input. By 'noisy' I mean there are misplaced pixels on the screen. I wondered if the problem might be the HDMI leads picking up interference from somewhere but the problem persists with different makes HDMI leads. The unit is under six months old and has been returned to Optoma twice for repair. The problem is fixed when I get the projector back but then reappears some time later. Stuart

SOURCE: Projector powers up as normal, bulb comes on,

There is a source lock and source button I would unlock source lock button and the push source button until you get to your hdmi input you are using. You also may just plug in one input first and once you get the input right play with the multiple hdmis

SOURCE: Help! Our Optoma DLP

There is a lense behind the main focus lense that's causing this. Flakes of the colored tint are coming off causing white light to shine through. If you look at your projection, you can see black spots as well, these being the flakes that have re-located themselves. I dug into mine deep enough to diagnose this, to actually replace the little lense would be a little tricky. The unit has to be mostly disassembled. Also I haven't been able to locate a vendor who sells the part. Optoma wants you to send it in so they can do the repair, and won't part w/ these component level parts.

Optoma HD80 flashing blue lights


Sound like the original color wheel for Optoma HD80 is bad.

If the unit has been moved when hot.

If not, try un-plugging the unit for a few minutes and re-connect.

Hope this helps

DVI-HDMI not working with Sanyo Z2


HD comes as 720p and 1080p - the Sanyo will cope with 720 but not 1080 full HD - check the specs in the manual. You should have a DVD output setting for screen mode.

Display resolution through dvi input HELP!


For the record I have a playstation 3 running to tx100 through hdmi to dvi adapter. It does all resolution no probs, including 720p,1080i and 1080p (which tx100 does do smoothly through dvi). My denon upscaling dvd player works fine too. In fact the tx100 looks totally awsome with PS3 games and Blu-ray.

Maybe your dvi lead is the wrong type (i think there are 2 types) or perhaps you could test with a differrent piece of DVI kit in case it's your pioneer causing probs? Hope this helps.
