HK 3480 sound suddenly cuts out
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.
I'm having a similar problem but I can't even find the fuses. Are they the traditional glass tubes or something different? Any help would be greatly appreciated. Thanks, Ray
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.
