DV10 problem I'm having the loud noise and i read you said it was the lamp. I was wondering if your lamp actually broke or something, because I can hear a rattling in mine.

it's the colorwheel. part# 70.81R26GR01. you can get the part and do it yourself, or send it to a service center. either way, av solutions in ny is pretty good (www.avsolutionsny.com). they can either get you the part or replace it for you.

I have sort of the same problem...there was a loud snap(kind of electical spark like) then the unit started humming loudly which changes sound as you move the unit around. The picture remains clear and the fan is quiet in shut down mode...still the wheel you think?

check the colour glass wheel is shattered with a piece of glass still stack to the wheel. it not even thats why it vibrates

Hi,

could be the brakes, if the loud noise is like a screech probably your brake rotor and lining need replacing.

Check and let me know.

Thanks.

the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.

hi,

Please Check and service the fans and the Air filters. then check again. In case the noise still comes then service the fans or replace accordingly. By complete service of projector, this will work.

Okay, I recently had a loud noise coming from my projector and found online meterial stating that the colour wheel had been damaged. So with a bit of guts I managed to open the projector and found the colour wheel missing a segment.

I removed the colour wheel and the broken piece of the segement and tried to contact Optoma. Optoma turned round and said they cannot sell me the the colour wheel, which got me very upset. Some people claim online that Optoma will sell you the part on a back order at £50. (if you can be a little specific on how you managed to convince them to sell you the part, would be great).

The only option I had available was to send my project to them and they would repair for an estimated cost of £125+VAT. Guess what, you can buy the entire projector off ebay for 150quid!!!

Anyways after fiddling around quite a big online I got fedup and decided to glue the broken segment together and it SOLVED the loud vibration problem. I have colour and picture.

Becareful not to tighten the colour wheel screw too tight orelse it will break another piece of segement (Like I did).

Here are instructions on how to open up the projector.

I cannot guarantee this will work for you as it depends on how badly you have shattered the colour wheel segment, so do at your own risk. I had two piece of the segment broken and a third by tightening the colour wheel screw too tight.

This will work for awhile but the colour wheel does need replaceing one day. If anyone can tell me how you can get Optoma to sell you the colour wheel would be great.

Best of Luck

Yes, you can replace the color wheel yourself if you are handy with a screwdriver.

it's the color wheel

It's the lamp. The same exact thing happened to me, my projector started making a loud whinning noise and the picture quality got really dim. At first i thought it was the fan too but after alittle online research i found out that that when the lamp bulb shatters it does this, so i went a got a replacement and it fixed all the problems. :)
