I did the cleaning procedure again and I can't get rid of one a green blob. How difficult is it to get to the mirrors? I have been blowing air on the green LCD without much luck, so I'm thinking the dust must be on one of the mirrors.

Is it possible to have dust on the mirrors? Its a green blob so I assumed its dust on the green panel. Looking inside the lens when the projector is on I can see what looks like a small hair, tiny fuzz.

Am I see dust on a lcd, mirror, or on the inside of the lens? I've blown quite a bit of air on the lcd panels and at the inside of the lens, and I can't get rid of this one fuzz. Maybe its burnt on a mirror.

Ideally you want to detach the LCD cable from the board in order to get a good shot of air into the panel area. Dust blobs show up best on the green LCD panel, however the dust could be on the red or blue panels. They should all be blown out.

A fine layer of dust itself will not show up on the screen, just dust blobs.

Use two cans of compressed air being careful not to let the liquid propellant out. When one gets too cold, switch to the other. Standing the projector on end so it is upright helps to keep the can of compressed air upright as well. Detach the ribbon cable from the board by flipping up the clamp that holds it in place. Using your compressed air work your way back and forth parallel to the LCD panel using a sweeping motion. Don't be stingy with the air, you want to dislodge it and blow it out of that area.

It's not unusual for people to try several times to get a dust blob out before it's finally blown out.

Had my 8350 for around two months...watched about a dozen movies on it. No gaming.

Tried to turn it on today and all I hear is a loud fan...and it can only be shut off from the main power switch. Unbelievable!

Hey guys

Hoping to gain a little insight here. Troubleshooting

Quick facts
original bulb 1500hrs
new generic bulb 4hrs
wont turn on without fiddling
once on all is perfect zero problems

OK when I press the on button it will usually display the epson logo then the lamp goes out. It does this three times then the red lamp light flashes.
If i pull the plug. toggle power switch sometimes pull lamp out/in it turns on fine and works perfect until it is shutdown again. This made me wonder if it was just a bulb problem or something more serious. I ordered a cheap generic bulb. Installed it, tested turning it off/on for a day or two and all was good again ( expect picture quality) Today I couldn't get it to start no matter what i tried. So I put the original bulb back in and it fired right up. Watched a movie turned it off. Turned it back on in the afternoon no problems again. Went to watch a movie tonight and it wont start again. Once again I fiddled around with it and got it going. Do you think it could just be a bulb problem or something more serious.

I followed your instructions, and got the blob out. Once I detached the ribbon cables I could see I wasn't blowing the air down far enough to work the panels before. So the 7th times the charm.

Thanks for the tips, and quick response.

Dust problem?

Hi!

I've read this topic quite long. My projector is about three years old. I've suffered from dust blobs some time and now i don't know what's up with it. When i turn focus all the way out the image has these little red and blue dots all around!

I've tried cleaning it many times. Today i pulled the main circuit board out and used a lot of air straight to the panels and still no help.
When i took the lamp off it had a lot of "glitter" fallen from it. So i was wondering could that been sucked inside of the pj? Can't yet attach images so...

Thanks in advance!
