Hi and Thanks again, Since the relay does not click on and i get 35vcd on that board, doesn't that indicate that there could be something wrong with one of the main amp boards because doesn't the relay protect the main amp??

If you are seeing 35 volts on the main amplifier output point of that board then that is why the relay doesn't click.

The relay is to protect the speakers as much as anything. 35 volts would destroy them instantly.

Usual cause of a high DC offset would be failed output transistors and drivers. Why they failed would also need investigating. Could be abuse by a previous owner or it might be dries or an intermittent fault on the board.
