Hi all, I've started this new thread in order to avoid further polution of thread "Yamaha RX-A3010 working, no sound output"
Just to recap:
No sound through Audio and AV analogue inputs, only sound when 2ch stereo or pure direct is activated (so no sound when I e.g. choose 7ch of Hall in Munich etc.). Hoever when I connect HDMI I've sound in all options (movie, music, eyc.) First suspicion was the DSP chip/PCB so I bought a scrap 1030 with a good functioning PCB (in this one a driver stage was defective (PRT DC: 67), after I swapped the PCB I've performed a factory reset to get the unit to live , ok then I upgraded to the latest FW version 1.98 also ok. However I still have the same issue.
Next steps were:
- Swap of Funcion-1 board >> issue still there
- Swap of operation(2), video(3) and digital(2) boards >> issue still there
- Afyer each swap a factorty reset has been executed
Now next step is trybing to follow audio stream with help of a scope (many tnx Budwich for all receommendations given) to determine where the issue may be.
