I have been using the beamer for 2 weeks now and it makes high pitched noises, a kind of beeping that is always a little different. I have tried all the settings but it doesn't go away. The noise is quite annoying. Does anyone have experience with this and know what I can do?

Hello Bolo, this is not the case with my device. However, I had this happen with a Benq where the power supply was defective. Maybe you'd better return it. Greetings
