I recieved this reciver as gift in december. after a few months of not having speakers, i bought some JBL's and everything was sounding great. however, now i'll be listening to music (mostly via a connected laptop) and it will just cut out.
i thought this maybe something odd, so i then just put the reciever on AM radio same thing, so obviously it has nothing to do with the cables. but just to be sure i've checked the cables (reciever -> amplifier & laptop -> reciever) nothing wrong. i'm not hitting mute on the remote, i'm not turning the wrong speakers on or off (i.e. speakers A instead of speakers B), and the power does not go out.
i know it's still under warranty. i just hope i don't have to get it fixed. because i'm just now able to enjoy it... sort of.
thanks.

Your fuses are blown by possible crossing speaker wire - and + together. I did this and kept turning it on but I ended up frying the unit. Check your wires and make sure that they are seperated properly. If problem continues then unscrew the shell and replace 1 or all 3 fuses (depending on what was blown) with GMA 8 amp fuses. good luck.
Try on lower volume and see if that happens. Also try different speakers with higher resistance. Your jbl are probably 4 ohms. Try 8 ohms
I did a system reset by unplugging the receiver from the wall for around an hour. I read this from Harmon Kardon maintenance manual. It worked perfectly for mine.

The same occurs with my HK3480 as well. I cannot even make it through both sides of a vinyl without the receiver suddenly cutting out. I can switch between phono and FM and the sound temporarily returns but for only a few seconds. This also happens when I switch between phono and tape mon. I hope it is something that I can fix instead of having to send it back
I Have the same problem. Every thing is fine during a few minutes. Just after it suddenly cut off and there is nothing to do... When I change the source (CD --> Tape or something else) I also have the sound during approximatively 1sec. I don't understand. It seems that the automatic protection is doing its job too often...
Yeah, me too. Cuts within seconds. No message about protection, and the behaviour only seem to apply to Speaker A. Tried to switch to Speaker B now and it's been playing for good 10 minutes without indications on cut. Not one of the three tube fuses are blown. Heeelp!
