Help Needed: Yamaha RX-V485 Network Issue After Firmware Update (WN9711 Error)
Hi everyone,
I’m facing an issue with my Yamaha RX-V485 receiver. During a firmware update, the process failed, and now the USB, Bluetooth, and network functionalities are not working. Occasionally, the receiver displays the error code WN9711.
I came across Yamaha Technical Bulletin No. 0103, which describes a similar issue for models like the RX-V4A, RX-V6A, and RX-A2A. According to the bulletin, the issue can be resolved by shorting soldering points (e.g., J260 for RX-V4A or J755 for RX-A2A) to reset the network module. Since the RX-V485 appears to use the same network module, I suspect a similar fix might apply.
However, I couldn’t find any documentation or information about the soldering points for the RX-V485. I’ve searched the service manual but had no luck identifying them.
Has anyone here encountered this issue with the RX-V485? If so, could you point me to the soldering points or share any advice on how to resolve this?
I’d appreciate any guidance, images, or steps that could help. Thanks in advance for your support!
Best regards,
Sanal Kumar
