I have a Yamaha RX-V495 - very recently the buttons on the receiver itself stopped responding - I cannot set Effect, pick Tuner presets, etc from the Receiver itself. I can do it through the remote control. The manual knobs (volume, bass, treble, source select, etc) all still work, it's the buttons! Very weird problem.... and since not all of the buttons are reflected on the remote, there's a few things I cannot do at all.
Any advice is appreciated.
