Issue with "Buzzing sound"

Several people have reported a “buzzing sound” in the Indiegogo campaign page

Someone has posted a video Philips Screeneo U5 (

It seems that some people get the issue, others do not. Unfortunately, I have it. That buzzing sound always happens at launch, the randomly comes up during use. My wife, children and I watched a movie yesterday as we were all happy to get the unit. The problem is that, in quiet moments during the movie, hearing that sound multiple times made us all cringe. This is a kind of showstopper. Is there any way to address this, or does it require the unit to be returned?

Here’s my own recording. We can hear this constant buzzing, coming up and down but always present. At moments it’s as ahigh as the fan.

Hi @Philips_Support_S . I saw this thread in Indiegogo Discussion page

Do I understand correctly that the units with that issue should be exchanged now?
