    Yamaha HTR-5460 Receiver protection code info.

    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 options has the problem. I have been unable to find any source for the Yamaha protection codes and their meaning.

    Can anyone direct me to a source of these codes or let me know what the “020 B” means?

    Thanks in advance Pete

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

      QN750Q8FNBFXZA Service Error Codes Needed - Error code 1-3-1-2 ? Dead set, only blinking standby light in repeating sequence
      by mecha1166
      I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks!

      Yamaha RX-797 going into protection
      by Francesc V.
      Hi:

      I am trying to rescue this Yamaha amplifier. It turns on, does some relé clics and then switwes off.

      Following up the service manual, I've entered into diagnosis mode (Fm + 8 + switch on during 3 secs to avoid protection). It shows the error shown in one of the pictures. If I am not misunderstood it might be a power supply issue.

      These are the voltages I am getting in CB272 connector (page 33)

      Amplifier just plugged in:

      S10 -> 9.7-10.3V (quite unstable voltage)
      PRY -> -122mV
      E -> -108mV
      ...

      GIGABYTE GA-H110M-S2 - Stuck at Debug Code C2 - don't like Patriot Viper Steel RAM but works with G.SKILL
      by DynaxSC
      Hi,

      I discovered a strange behaviour of GIGABYTE GA-H110M-S2 board.

      General test conditions:
      - Tested with Core i5 6500 and Core I7 6700K - no difference
      - Default BIOS settings, but tried also altering several memory setting - does not change anything

      What is wrong:

      With BIOS F1 and F2 the board normally POST's and boots to Windows 11 with 2 x Patriot Viper Steel PVS416G440C9K RAM (4400MHZ, Samsung B-Die chips)

      When BIOS upgraded to anything above F2 (ie. F20-F27b) the board POST stucks after 3 Debug Codes on Code C2      ...
