Hello,
My Harman Kardon 635, which I have for several years, has been causing problems with the sound reproduction of the left channel for some time. When I switch it on, it works normally for a while, but at some point I notice that the sound gets quieter and quieter. I then press all the front buttons and switches and at some point the volume returns. This also happens when the sound is suddenly very loud during playback (as if the amplifier has fallen asleep and suddenly wakes up again).
Does anyone have any ideas?
Thanks.

Hi!
If this happens only in the left first channel, it is probably a contact problem, in one of the connectors
Unfortunately, it is difficult to find the exact location of the problem, because where it is, where it is not.
