Buzzing noise, trying to open the cover

We turned the projector on, heard a pop and now a loud buzzing noise. We were able to open the side and were able to take the lightbulb out but now were trying to open the entire cover and are unable. Are we missing something to open it? thanks

It sounds like a piece of your colour wheel has fallen off. You will need to take the front panel off (2 screws) plus the two plastic rings around the lens pull out. Be careful not to snap a circuit that sticks out behind the remote sensor on the front. I've had this problem a few times but have just glued it in with 24 hour drying glue, the noise i had was so loud it was hard to watch anything, plus i lost the red colour to the picture until i glued it back in.

Optoma th1020 - heard loud "pop" and now projector vibrates violently. Shaking so much that it cant stay in focus


Sounds to me like a blade has come adrift from one of the cooling fans in the unit, throwing the fan out of balance (The pop you heard will have been from the pice of plastic being ejected from the fan). Unless you are experienced in electronic servicing, I would not advise opening the unit to identify which fan - you'll almost certainly have to take it to an authorised repairer anyway since these fans are usually highly customised units

PT-AX200U Bulb replaced 4 months ago Was on about


carefully take the lamp cover off, and see if there is any glass pieces inside. if all looks Ok, then unscrew the lamp housing and remove the lamp. check for any damage. be careful not to damage the lamp or bump it. These lamps generally contain mercury vapour, so try not to inhale anything if it's broken.

How do I open it for troubleshooting? I need to look inside for a blown component. Projector popped while using it and light went out suddenly. I have testedf with a new lamp but no go.


first pop the focus ring of the lens assy using a wide flat head. remove 8 screws on the bottom,2 or 3 on the rear. pry the bottom of the front bezel away from the bottom of the projector being careful not to damage the tabs that hold the bezel to the top. repeat the same for the rear bezel, disconnect the speaker and the keypad from the top cover and remove the top cover. most likely the pop you heard would be the glass fuse on the power supply on the side next to the lamp door, but also could have been the power input board next to the on/off switch, OR the lamp may have exploded.

Projector stays on for 3 minutes then turns itself off


Hi Chipped Rice

The loud buzzing noise you heard was the colourwheel that gave in.

Now what happens is , the machine will turn on and go through the whole cycle and as soon as the colourwheel is supposed to start doing it's stuff the Projector will switch off because there is no response from the coulourwheel itself.

You will have to replace the colourwheel unfortunately as it cannot be fixed.

Thanks for using Fixya !

Infocus SP4805 buzzing noise


Hi dcabbarno

The buzzing noise is a broken colourwheel and the shadow could be a part of the colourwheel that is obstructing the light engine or it could be your packlight pipe ( tunnel with 4 tiny mirrors in it ) that was damaged when the colourwheel broke.

I do unfortunately not have the part numbers of the parts that I mentioned , but you could assist by opening up the unit and supplying me with the part numbers.

The colourwheel you will spot straight away once you've taken off the top cover of the Projector , the packlight pipe is situated right next to it - looks like a small tunnel that's got 4 mirrors inside it - takes the light into the light engine.

Once you've supplied me with these I can get you prices and places to order it from and will help you with instructins on how to replace them - it is quite easy to DIY.

Thanks for using Fixya !

Horrible noise


it is the color wheel i have a similar problem and am looking for the part, the color wheel is a small electric motor that spins at a high speed and it can go bad. which will lead to the horrible squeel/hum/buzz.
