I would suggest that you swap the SSM with a another SSM from a working channel and do some testing again. If channel 4 continues to have the same problem, the problem is not with the SSM. While you have the E2+ open, try pressing down all chips ( beware of static !!! and do not have the E2+ connected to mainspower ) that are mounted in sockets. I do not think this is a powersupply problem. It is a heat-related problem for sure.....
