All Remote Controls Of My Lm 1345 Stop Working Suddenly. Door Control Still Ok.

All remote controls of my LM 1345 stop working all the sudden. When I press the transmit button on any remote control, the yellow LED on the back panel of the receiver will flash, but the door won't open. But if I press the door control, the door works fine. I have reprogrammed the receiver serveral times to relearn the remote code. But it didn't help. Do I need to replace the logic circuit board? Thanks
