    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.

      Lenovo Thinkpad E14 Gen3 stuck on "To interrupt normal startup, press Enter" screen
      by BMCappelletti
      Hi everyone.
      Lenovo Thinkpad E14 Gen 3, stuck on the "To interrupt normal startup, press Enter" screen.
      Found a lot of people with this issue, but with no definitive answer. Some people managed to get away accessing BIOS, going to Startup and turning off "Option Key Display". For me that only removed the interrupt normal start up message, leaving only the Lenovo logo.
      Most people say hitting Enter does not work. It's true, if you wait a few seconds. But if you hit Enter right away you get the options to enter BIOS (which works), run diagnostics (goes to a...

      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...

      YAMAHA CLP-550 without of sound
      by AlexVG
      Hi.
      I have an old YAMAHA CLP-550 without sound. (Some times I can get some kind of noise or distorted sound)
      I have replaced all green marked elements, but it gave me nothing.
      The IC12 chip LC9116A-105 (red marked) remains under suspicion yet.

      But it is custom YAMAHA's chip, and I can't find any information about it.
      Maybe somebody came across with the same issue?
      Any information will be very useful. I will be very appreciated.
      Thank you....
