You probably have issues with caps in the power supply....I would check that it up and look for buldging caps and replace any that you find....

Mackie Music | Answered on Sep 27, 2019

I had the same issue and the solution was to exchange all electrolytic capacitors in the power supply. The used "Jamicon" capacitors were all way below their expected values. However the most important capacitor to change is located just next to the switchmode transformer. It is covered with heatshrinkable tubing, so at first I didn't recognize it as a capacitor, and thus exhanging all capacitors on the secondary side helped, the issue didn't go away for good - it still sometimes blinked during startup. This capacitor (10uF/50V) looks like it smoothes a DC voltage to the SMP controller. The ripple voltage across it was substantial and desoldered, it showed som 3.3uF instead of the 10uF it was supposed. Changing it to a new 10uF/50V solved the blinking issue for good.
(I'm aware that the question is old, but I answered it so that new folks with the issue might find this answer when "googling" for aswers)

If you havent ground looped the chanels. Most of the time the chanels need to be cleaned.

If all other functions work for those channels, the most likely problem is the fader itself. These can fail and operate more like switches rather than faders. Without witnessing the behavior, I can not state that for sure. While these mixers are not the hardest to work on, they are time consuming. The faders can be purchased from Mackie directly. If you need to have this repaired, any shop that repairs audio gear should be able to erpair this for you. Where are you located?

Sounds like an earthing problem , check your cables and make sure none of the cables have strands that could be shorting down to earth causing the buzz
