RM100KH - 2 dead channels

IDK if anyone can point me in the right direction here, but I'd appreciate it.

I have an RM100KH. The other night the footswitch came loose. Upon reconnecting it, I lost channels 2 and 3. No matter what modules are in which slot, only Slot 1 functions fully. Slots 2 and 3 give no sound, slot 2 doesn't light up, slot 3 always has faint light on the indicator LED. This is where it gets weird, the footswitch is still getting power. I can select all three channels with it, but only channel 1 works. Any advice (even if said advice is the phone number to an Amp Tech in the Pocono Mountain region) would be much appreciated. Ideally, I'd like to troubleshoot it myself but...hey, ideals are meant to be fallen short of!

Thanks in advance

I'm assuming you took it out again, and checked the pins, then reseated it, correct?

Did you unplug it and plug it back in while the amp was on? If so you probably fried the midi board.
