I have some oldschool one
Will measure voltage on regulators. The problem is when I come home I feel so tired. Will bring the board to my work then......

Okay, I've replaced ALL capacitors. But the problem remained.
The noise remains even after I unplug the power cord, until the input caps are discharged.

Yeah, it moves up to a centimetre back and forward at a random rate.
Maybe it affects the hi-freq section as well, but since the tweeter is unable to do a low-freq (plus that crossover) I can't tell for sure. Need an oscilloscope.Leave a comment:

Nope, tweeter is silent - woofer is sick.
Will check the power supply then. I'm glad I have 3 monitors btw.Leave a comment:

Yes, and this low-freq noise interfere with the audio, making it much quiter and with much less lows.
I've looked inside - all caps look fine.Leave a comment:

Here's my problem.

I've had the same problem with other monitors, and it's not a potentiometer. The issue remains even when I unplug the input and deattach the power cord (the monitor keeps working for a second using capacitors).Re: Repairing Alesis M1 Active mk2 M...ntiometer. TheLeave a comment:
