Dear,
I have a problem with a digital mixer Behringer DDX3216.
The all faders only work on the top .
When you turn down the faders, the LCD loses the fader position and the sound comes and goes.
Attached video the LCD.

I changed all the capacitors of the PSU, all the correct voltages and the problem is the same.
