Since you don't know the history of the PA, I'd agree that 90% of the problems will lay in the molex connectors that jump from channel to channel. Not sure how much you want to dive into fixing it yourself but, if the last channel is working, the plug that feeding it seems to be working, you might want to remove the first channel out of the chassis and swap itto the working channel, if that works, then I'd guess your problem is in the connector plugs and a good cleaning of the actual plugs should bring all the channels back to life. My guess is, if you swap all the non working channels into the channel slot that is working and they don't work in the channel 6 spot, then I would guess someone at some time took a line from a speaker output and plugged it into the input of the non working channels, frying the pre amp.
Keep us posted
