Blown (?) right channel on HK amp still making a little noise

My Harman Kardon 3490 stereo receiver/amp has a very weak channel. But, it still makes a little sound. I've been known to turn it way up re stupidity. Playing with the balance and volume can give me a lock out and a message 'check amp.' I'm just a chemical engineer, so help me understand how an electronic device can be 'kind of blown.' Thanks
