No fault indicator leds on ? Activity led works ? Do you hear nothing at all... I mean a faint hiss or humming from that channel.
I have two P7000.
Check if there are relays inside and if they click.
Check for correct rail voltages.
Check broken / cold solder on connectors.
Schematics here. Perhaps It can help
