I recently bought the optoma 25 hd 3D and last couple of days I get a warning signal that I need to change or replace my filter, thing is there is no visible filter which makes things complicated! Anybody???
Hi Cathy,
The replacement of the filter is something that needs to be done at a service center by a trained technician. If you are interested, feel free to send us a message: Projector Repair Bulb Replacement

you need to reset the lamp timer, usually done by holding some buttons while turning on

Most projectors have air filters. Yours may need to be removed and cleaned. No air flow = overheat.

I removed the front cover and top panel, Using the Radio Shack dust removing spray, removed all dust from interior including circuit boards, color wheel ect, now it,s operating like a new projector.

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

Asher fadida and alll,
The issue:
solid red error light?
HD70 "die's" after few min with strage noise?
flickers different colors before complete self shutdown?
well try this....
Before replacing your bulb, fan or any other component try first cleaning your optoma realy good!! HD70 doesnt comes with any kind of filter so you can imagine the amound of dust can be.
The most importent thing is to blow away any dust from your color wheel + the sensor attached to it .
for farther troubleshoting clean your fan's.
there are 2 fan's insinde the HD70.
probably the most problems will be solved by cleening the color wheel!!
if the problem is not solved ,chack the lemp and the fans if they work properlly.
For fan replacing:
Fan Part number: GM1207PKVX-A
Good luck!!
