After installing today’s update, which lowers the fan noise, I’ve noticed low-pitched buzz noise coming probably from the light source. It appears when using at least:
Normal brightness mode with unplugged charger EDIT: this one is pitched higher and is hardly audible
Energy saving mode with plugged charger
Honestly I find this buzz noise more annoying than the previous fan noise, which masked it.
Does anyone else have this kind of problem? This might be matter only of faulty unit.
Now I’ve found out that it’s actually more audible (and low-pitched) when power is drawn from the charger. Not immidiately when it is plugged, I guess light changes the source of the power from battery to external (to preserve battery health).
How close or far away are you from the projector to hear this buzz?
I too noticed the buzzing in the morning straight after the update, that’s because I can’t hear any fan noise and I was worried, so I stuck my ears right up to it,
But to me that was just an electrical device especially with a bright light humming, which seemed normal when the room is dead quiet, unless you can hear it from a fair distance away then I wouldn’t worry about it
Honestly, maybe it’s my phone but it didn’t change much (around 44dB vs 45dB). Different frequencies might be less or more annoying, while staying within same intensity.
I’ve been using it a little bit and it really occurs only when charger is connected, no matter of the brightness setting. And it’s clearly coming from the light source, when it switches to draw power from adapter. I still find it quite annoying, sadly got noone around to compare it.
I’ve also noticed this sound, I had been testing with FW 1.0.32 which had the fan noise reduction and did not have this extra noise. It is so apparent that I even thought at first that the adaptive fan control did not make it into the FW 1.1.0 version, and reported this. It’s only after your post that I tested and indeed discovered it’s coming from the light engine when powered. I know this as indeed it only starts when the light output becomes brighter when powered, a second or so after plugging in.
I’ll downgrade to 1.0.32 later this week to see if this changes anything.
Yeh I’m getting the buzz noise when plugged in, & goes away when turned off it’s abit annoying & normal mode the noise level fan hasn’t really changed much
