You say that you have tried a different MCL cable - does that mean that you have also checked the connections inside each MCL2A and MCL2AV box - I would check that all the connections are secure.
Second thing that I would check is the option settings, for the Beomaster and each link room - re-do the whole system with the correct options, and make sure you do so with the system powered down.
EDIT: If no video products also connected, options should be set as follows:
Main Room (BM7000) - A.OPT 1
Link rooms: L.OPT 2.6 (set L.OPT 2 then set L.OPT 6 afterwards) - check that each transceiver blinks to acknowledge setting. An additional requirement may be to hold time the Timer button on each transceiver and send an AV command with the remote - I think that the transceiver should again blink to acknowledge.
