    Yamaha RX-V485 receiver. After encountering a "version error"

    Hi everyone,
    I'm having trouble with my Yamaha RX-V485 receiver. After encountering a "version error", the USB, Bluetooth, and network functions have stopped working, making it impossible to perform a firmware update through normal methods.
    After doing some research on forums, I found that earlier Yamaha models with similar issues (like the internal error message) could be fixed by shorting or soldering specific pads—such as R896—and then powering on the unit to enter a service/boot mode that displays the model info and allows recovery.
    I managed to find the service manual for the RX-V485, and it seems that similar soldering points exist: specifically J207 and CB29. I tried soldering these points together as suggested in other model threads, but unfortunately, nothing changed—the receiver just starts up normally, and the error persists.
    Has anyone successfully fixed this issue on the RX-V485 or a similar model?
    Any insight into how to properly enter recovery mode or bypass the version error would be greatly appreciated.
    Thanks in advance!

      Yamaha HTR-5460 Receiver protection code info.
      by Pete D
      Hi Guys, My first time on the forum.

      I have a Yamaha HTR-5460 Receiver that I have used for a few years. It has recently developed a problem of giving a pop in the speakers and then shutting down. This is intermittent and might happen after an hour or a couple of days of playing.

      I have put it into Diagnostic Mode and it comes up with code “PS PRT 020 B”. According to the service manual “PS PRT” signifies a power supply problem in the mains transformer, 5V or 12V DC supplies. I'm assuming that the “020 B” part of the code would define which one of these...

      Running out of Ideas, hoping someone smart can provide some for my ONKYO TX-SR353 Receiver
      by CDNBrewer
      Hello Everyone,

      I have an Onkyo TX-SR353 Audio/Video Receiver (5.1 ch with HDMI) that I am having a really hard time diagnosing and I'm about to throw this in the junk and go buy a new unit that is on sale until the 7th.

      Symptoms:
      • Intermittent (part of the reason why i'm having a hard time isolating problem), sometimes will work for 10+h at a time without issue
      • Original symptom was wife reported loud banging noise (like someone was banging on the wall with their fists) from the LEFT SURROUND speaker and then the unit shut off.
      • I swapped the Left and Right surround
