Hello I'm hoping you can help me with a fault my Audio Access PX700 multiroom audio controller has. I recently disconnected the keypad in one of the rooms during redecoration. While the keypad was disconnected the audio system was briefly still in use. I'm not sure if touching wires caused the system to short but all the keypads in the house no longer work. I replaced the fuse in the PX700 as the old one had broken but the system still doesn't work. There are no Audio Access dealers in UK so I'm rather stuck with this problem. Please can you tell me if there is something else I can check or replace to fix this fault?
