Today while I was watching Prime Video, my PPM suddenly froze, I got a very loud noise coming out of the unit (sound like a mechanical noise/rotating part out of axis, relatively high frequency - sorry, I’m not authorised to upload the short video of the noise) and the remote and the unit were unresponsive (Impossible to go back to the home screen for example or to have any key responding to command or to stop the unit via the remote). I unplugged the charging cable but it did not change anything.
It took me few trial to stops the unit with the stand-by button (few trial of long pressing on the button, like more than 10 seconds). After restarting the unit (waited about 2 minutes after stoping it), it worked just fine (I only used it for 30 minutes after the interruption).
Prior to the issue I had the unit working fine for few hours in a row in different mode (screen mirroring, USB-C connection and Prime Video). The unit was not hot, even not warm as you could expect from a projector like this running for few hours…
Anybody with similar issue? Anything to watch to avoid it happening again? Any log file I could download to support some troubleshooting if necessary?
I had no major issue with the PPM until now, only the WiFi dropping off after 1:00 watching movies (even with only one wifi network (2,4GHz and 5 GHz) in a remote area…), but disabling Bluetooth seems to make the trick to watch a full movie without interruption.
