Hi i have the same projector you will not solve a coil whine issue because the power supply is not the problem , it is the normal sound of the color wheels spinning at 5000 rpm \high frequency noise made by the motor that drives them , with your cooling issue the color wheels and laser temps are monitored at multiple points with TCs and fans will ramp up according to the temps measured .a mod that could be attempted would be water cooling but this is a complex piece of tech and dissipating the heat away would be complicated .The Xiaomi is a great device (after having it fixed with the plate from [email protected]). With the latest ProjecTivy Tools from XDA you can setup different display profiles for HDR/SDR wich is a another great improvement.
The only thing which is bugging me is the coil whine. Interestingly the whine is almost not existent in 3D-Mode. In 2D-Mode its much louder when the light mode is set to "Movie" as opposed to "Hightlight" mode.
So i tried a solution with a modified Ikea tv bank as an encasement (see pictures attached). The solution is effectively eliminating the coil whine. But now i run into heat problems. I tried adding some usb powered pc fans, but after one hour in "Movie"-Mode i get a heat warning from the projector.

I think the biggest problem is the heat sink (see attached picture). Measured with a heat gun it is getting to ~55 degrees Celsius in Movie-Mode and up to 66 degrees Celsius in Hightlight-Mode. The other side of the UST where the two fans reside is only getting to ~22 degrees Celsius.

The thing with the coil whine is, it is originating from the side with the heat sink. So to block it of i have to enclose it but then i am running into heat problems. At the moment i am out of ideas regarding the coil whine.
Has anybody found a better solution regarding to the coil whine issue?
I've the center speaker infront of the PJ. No problems.Hi
I have wemax a300 and 5.2 audio system
I have problem where to place my centre speaker. My shelf is wide enough to have tge speaker righ in front of the projector but I was concerned if the speaker will have negative effects on the projector.
Please let me know your opinion.
No. It has to be powered on by the remote. If one was to lose the remote, they will have a very expensive paperweight. I have not seen any replacements for the included remote. You can control the projector with the MiHome app AFTER its powered on.I’m looking at the 1S and I’m wondering if these are able to be powered off/on with an outlet that switches off and on?
You can turn on by unplugging from the wall and plug it right back....you can do that using a smart plug I guess.No. It has to be powered on by the remote.

Replace this metal plate will solve the problem on Vertical lines and Snow white dots.These lines have become a real issue.
Do you have the lines in the MI Menu (with all the Chinese apps)?
