Question about Harman Kardon AVR 55 Receiver

1 Answer

AVR55 switches to the standby mode Automatically.

After the receiver has been on for approx. 5 minutes or less it switches to standby and orange is backlighting the power switch. I have checked all of the cables in back and all are tight.  I recently took 13 days vacation and unplugged the power strip before I left.  It was working as advertised before this.  I returned and pluged it in and now it wont stay on.  I read the manuel and it said that the processor may have loaded wrong and to unplug it for 3 minutes and try to repower the system.  I did and no joy.  The receiver does not ever feel hot or for that matter warm.  We primarily use it for movies with digital surround.

Mine did the same thing and it was a faulty fuse that was the problem. The cover to the receiver comes off with a small phillips head screwdriver and there are small glass fuses inside it. Remove them one by one, due to different amperages, and check for dis-coloration on or in the glass. Be sure to do this one fuse at a time because the fuses are different rates and need to be replaced in the same spot. If the fuse looks burnt or dis-colored replace it and that may fix the problem.

Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps2_bing.gif metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers2_bing.gif are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

Standby mode, shuts off


After 10 years of use probably best to replace with a new unit. Most will be hard to find exactly wich little bit is broke.
