Hi,
My Onkyo HT-R494 front panel's all buttons including volume + Standby got Frozen.
It is luckily connected with TV with CEC HDMI ARC before it jammed so working fine with movie and audio.
But, cant change input and cant use any of the front panel buttons and also cannot be reset as buttons are not working.

Any idea how to fix, can I reset through motherboard or EEPROM??
Any idea/help would be appreciated.

The first thing to do is disconnect the power to the receiver for a few minutes. It could take up to 30 minutes, but five usually does it. Reconnect the power and turn it on. Often things can get "stuck" and the only way to fix it is to fully bleed the power so it resets itself.

Already tried that But, No Luck.

I am afraid because Onkyo is not in my city and it is out of warranty as well.
Checked Onkyo datasheet where it said that wiring from MMP to buttons is NG.
i checked with multi-meter wiring was OK
