Had the same problem with my RX-A2010 and have now solved it.

Running Self Diagnostic Test C2.1 on the receiver didn't get anything, neither ok or faulty. Couldn't even check the firmware version. So with that test it seemed the problem lay within the DSP2 chipset on the Digital 2 P.C.B.

Checked the possibility to order a new Digital 2 P.C.B. and they are still available for around €100.

I thought I'll first will try to bake the PCB in the oven before I order a replacement.

Placed it on a piece of wood in the oven on 200°C (392°F) for 15 minutes with the DSP2-chip facing down and resting straight with help of the board power socket, chassi mounting and the cable tie that is mounted on the board. I let it cool down and then mounted it again and now it works perfectly and the self diagnostic test are all ok regarding firmware version, checksum and the bus signal to the DSP2.
