So i have a problem with my Mi Box (MDZ-16-AB). After i turn it off or i turn the TV off (its conected by the HDMI cable), the Mi Box makes weird, squeeking sounds. They are not so loud but extremely high which makes them unbearable. Interesting fact is that the box makes them only when i turn it off or when i turn the TV off - it doesnt make no sounds when its plugged to the TV and both the TV and Box are on. It gets so annoying that i have to turn it off from the power when I am not using it because i cant stand the noise. Do you know the solution to this problem?
I've came to the conclusion that the problem is the power supply, at least it is in my case. I've solved by using an old psp charger since it have the same connector and voltage/amp. If you have I've, give it a try after checking the specs.
