Power supply noisy

Hi,

now it’s in the bedroom, I noticed that my picopix power supply is really noisy/whistly.
I’m not so confident in its durability.
How can I replace it ?

Thanks

Hello, when my power supply is connected to my PPM, I can hear something like a whistle, but it comes from the PPM itself, and not from the power supply unit. Perhaps is it the same with yours?

I have the same problem. When projector is off, and fully charged but the power supply still connected, it makes an “electronic” noise, that is synced to the flashing light on the projector. The sound comes from the power adapter, not the projector.

It’s incredibly annoying, since I keep it in my bedroom and can’t listen to it when I try to sleep. It’s not “loud” but VERY noticable in a quiet room when your head is only a few meters from the power adapter.

I assume this is a defect, what is the process to get it replaced?
