Common problem in Marantz NR1601 AV receiver amplifier

Fault :- No audio from any channel.

Solution :- Make the system factory reset by press and hold the tuner + and tuner – button together in standby condition, release the two button when display start flashing at interval of about 1 second, then follow the instruction on TV or projector screen, finish all the steps on screen, when complete it then try with input signal through HDMI cable. Hopefully it will work.

If the problem still persists then try to update the firmware through USB which is freely available online.

If the problem still persists then check all the input signals like analogue coaxial and optical too, if there is no sound on any kind of signal mode that means the problem is in HDMI card and it has to be replaced or to be repaired by authorized service Center.

If you found the HDMI card is perfect then the problem is in pre amplifier or main power amplifier section.
