First thing to do is remove all speakers and power up again, if still going into protect mode then there is possibly DC appearing on the output. This is most often due to a failed output stage requiring a technician to repair...

Sorry for the delay..
I had waited for your answer but then had to go out...
Your service manual is here:
P700 is the Main Amp board and it is the speaker outputs from here that need to be checked for the presence of DC. These speaker outputs are fed through P800 for protection switching.
But first check all the connections between P700 and P800 as well as through the speaker switch. I would be testing the speaker switches using a multimeter on resistance range..
If all good then start looking for DC on the output stage comparing the two channels against each other and the schematic
