• Zone connectors at MRC-8/8.4e not secure
• Connector at Keypad to MRC-8/8.4e not secure

orientation at the MRC-8e/8.4e,and the keypad.They may be inadvertently reversed

LED does light
You are getting power and command connectivity to the zone.Check other zones and select
each source to determine if this is specific to a source,or the room in general.If the problem
is in a particular room,then there may be an issue with cabling to your speakers,or the
keypad itself.
If you get similar results for a particular source in multiple zones,then there may be an issue
with the source equipment,and you should check to see that the selected source is‘playing’.
If every other zone is ok,check to make sure cables to the speakers are secure,and that you
have tried to increase the volume level in that zone.
