Optoma DV10 projetor suddenly started made popping sound

On an Optoma DV10 if its not the lamp timer, then it might be a cooling fan that needs replacing. Take out the old one, and look-up its part number online. If you don't feel confident taking it apart, have a qualified person do this.

I just fixed one Optoma DV10 that was dead, cold joints in power supply; resoldered and work fine now.

there are dvd cleaning disks that work ok. you can get them at best buy or radio shack. they'll just lightly brush the dust off of the lens on the optical pickup. if the unit is is humid conditions, you'll need to use a lint free microfiber lens cloth and gently brush the dirt off of the lens. if there is stuff stuck to it, you'll need denatured alcohol with a scratch free fiber swab to wash off the lens (don't use a lot of alcohol). blow it dry and test it out.

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

I have the same issue, I have figured out its a fan issue, my fan must have went out. After about ten minutes the bulb will get too hot and the picture will start to turn a way off tint color. I put a fan on my projector and after about 40 min. the picture returned to the appropriate color. I am still investigation on how to get and replace the fan.

i had same problem so i opened up the casing of the projector and blew the dust off the inside components. it has been two days without the problem and the picture quality is better. probably an overheating problem due to all the dust. just be careful when taking it apart because there are a few cables to disconnect and a bunch of hidden screws, if it's still under warranty or you don't feel confident taking it apart, i'd send it in to get fixed.

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

have you hit mute.

Hook the coax line into a source with a built in tv tuner line a VCR or an LG DVD Player/Recorder.

Then run the connect the picture output from the source to one of the Optoma's picture inputs.

Use the source's remote control to flip channels.

If you want to use the Optoma's speakers too, then just run the audio outplugs into the Optoma's audio input. Done.
