It seems that my remote control is not responding to any commands unless I stand 2ft away from my component. I own a Yamaha CX-A5100 and it sits in an AV cabinet with metal mesh doors that you can see through. My sitting area is 14ft from my cabinet and have always been able to use the remote with the doors closed. Now, I have to open the door on the AV cabinet for the Yamaha to respond to commands. I have changed the batteries on the remote and even unplugged the CX-A5100 for 15 minutes to see if would reset. I'm pretty sure the IR sensor is not working properly and the further away I stand, the worse it gets. Yamaha has not responded regarding this issue. Just looking for any ideas or do I just need a new remote?
