Question about Audio Players & Recorders
I have a problem with my H/K AVR 5000 build in 2001: It suddenly switches back into standby without any reason. This usually happens approx 2 min after I have switched it on, but could be also after a few hours. After this it fails to get switched on again and immediately jumps back into standby.
There is a good chance that it works again the next day, but this is not for sure. This behaviour is independent from the source or volume (I believe). I already un- and replugged all wires including those of the loudspeakers. Even a reset of the amp did not help.
My first guess was that the protection curcuit is being triggered, however the standby LEDs remains orange and does no turn red as it should be in this case according to the manual.
Perhaps it is worth to mention that on very rare occasions the amp turns up the volume by itself at least I did not press any button on the remote control. This started a few years ago, but I could live with that.
Any ideas or experience with other AVR models?
Many thanks in advance,

It may be your unit is going into protect mode because of a problem in the power amp stage of your amp. If so, then it is time to see a repair shop. Good luck.

Ypou have an intermittent problem that sounds to be heat related... the more work the amp does, the more heat generated by the output stages. This will be aggravating some poor solder joints that are cracked or dry. The unit needs some repair work done in these areas. If you have good experience with a soldering iron, the cure for this is to resolder the power stages of the unit, or any other solder joints that look to be failing.
