Yamaha RX-V773 not responding

Hi.
I have a receiver Yamaha RX-V773. I have every voltage on board, but not able to power on. No stanby led, no voltage on PRY. If i want to enter in diagnostic mode, just write the model number on front display. If i press pure direct to enter in usb update mode than have this on front display(see the picture)
I don't know what i do. The mcu is faulty?
Thank you for help.
