    Yahama RX-V1400RDS in 30 seconds Standby repair

    Yamaha RX-V1400RDS (titan) THX Select Receiver with 7 power amplifiers and room acoustic analysis / equalizer
    After being switched on, the device jumps to standby for approx. 30 seconds and does not work anymore and you have to switch it on again and after 30 seconds the same problem

    thank you

    I think you have to explain your problem in much better detail. Did you try different output modes, or other settings? Does it display an error message? etc.

      Hello.

      I have a Yamaha RX-V 1400RDS here, the receiver is about 5 years old.
      The receiver can no longer be switched on.

      At first it started after being disconnected from the network and then ran for hours.
      Now it can no longer be switched on.
      The device never got too hot.
      He was often on standby for a long time.

            The following error pattern:

            After switching on via the power / stby button at the front, relay R371 clicks, the display goes on and after 1-2 seconds it goes off again with another click of the relay.

            The process can be repeated over and over, nothing changes. During the time the display is briefly on, you can change settings such as volume etc.

            Nothing is connected to the device and the inside is cleaned.

              Its sounds like a Output transistor is Bad or a leaking Monolythic cap on the power supply board which is separate from the main board look at the relay their are two caps their the one that runs off the relay line is leaking
              22nf from memory I don't have the schematic in front of me
              I work on these units all the time and its one of 3 things
              the other problem is the Bios chip on the Digital board can go corrupt
              check the standby circuit is getting a 3.3vdc pulse when you push the power button
              check the relay at the power supply is seeing the 2.3v signal
