    Hello,

    Yesterday I was watching a movie, and my HK AVR 147 just stopped working, and I could heard the relay switching off.
    I turn off the amplifier, and turn it on after 2 minutes, and it started to work for about a couple of seconds, and stopped again (again with a relay noise).
    Now, it doesn't work at all.
    I power the amplifier, it stays on standby (amber color). When I hit the button to start the amplifier, it turns blue, but with no relay switching noise. After 10 seconds, it returns automaticaly to Standby mode, with the amber color.

    Could anyone help me on this matter?
    I already checked the fuse, and it's OK.

    I forgot to mention that I have no lcd data when the led is blue (about 10 sec, then it goes automatically to standby).

    Have you searched online for the service manual? If there is one, it will likely have a troubleshooting section.
