Questions on first fix

I am attempting my first repair on an amp. The patient in guestion is a phase linear A 60 amp. The symptoms are one chanel works fine the other has a fault signal on the front panel and no sound. I have the service manual and have checked the transistors which all check out fine as do the fuses. The amp boards are modular and interchangeable so I switched them from side to side and the side that had no sound worked on the good side but still showed a fault on the front panel, the manual says to check the IC on the input but I cannot get the probes into the space provided so can I pull the amp boards to check the test points or do the boards need to be installed to make it test properly. This is where I stopped on the trouble shooting. I will have more questions to follow but right now this is it.
Thanks Brian
