Question about Harman Kardon AVR 630 Receiver
This is often caused by a defective tact switch on the front panel. With the system turned off, try puching all of the switches on the front( except power on). You should feel the switch engage. If not, then the switch is likely to be faulty and require replacement. Parts cost should be in the $5 range.
