This is the service manual.

This is the standby control circuit.

My first guess is the relay on the lower right is stuck, or the control circuit has a malfunction and is holding the relay closed.

Q575 turns it off/on and is controlled directly by the micro. Standby/SysV6 circuitry on the micro schematic sheet may also be involved.
