Without knowing how you have your monitors configured it is hard to analyze what you have posted.
In brief, SW3 on the schematic that selects MAIN L and MAIN R in the upper position, MAIN and MONITOR in the middle, and bridged in the lower is used to configure the internal amps.
In the upper position, the amp power outputs come from the mixed stereo bus and are simultaneously controlled as a stereo signal by the MAIN slider.
In the middle position MAIN and MONITOR, the left amp receives the signal from the mix bus and is controlled by the MAIN slider. The MONITOR output from the other side of the power amp is controlled ONLY by possibly the "MONO" slider.
The schematics are hard to decode and what is needed is a signal flow diagram.
For my uses, I don't try to use splitting the power amps between mains and monitor but prefer to use the mains together with SW3 in the upper position (Note your 27 may be refering to the user manual designation for same switch). I then use another small amp from the 1/4 inch MONITOR jacks whcih are under control of the MONITOR sliders.
Please note that the MIX for these two MONITOR channels is controlled by the MON1 and MON2 knobs for each channel.

Usual problem is the Channel A amplifier has burned and blown the switching transistors. Usually an internal board arc occurs and unless very skilled at board work of clearing the burned area and replacing the components you are better to replace the HCA2400 amplifier module... about $160

In spite of the display, does the effects work and do they change when you dial up and press the knob down? If they do, then likely the display is at fault. If the effects are NOT working sound wise, check the +5 volts as the whole effects runs from that, It should be within 10% of the 5 volts.
