Question about Optoma TH1020 Projector
Need help ASAP!
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

Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.
I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

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.

I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.
