problem with front right channel on HK receiver.
ok, heres my problem...... on my Harman kardon receiver, avr320, the front right channel is not working properly. you can barely hear anything coming from the speaker. i have checked all the connections and everything is secure, so im guessing it is something internal. any ideas what is wrong, and if it is something i can repair on my own??. a local HK dealer has quoted me $200+ to fix the channel and if its an easy fix id rather do it myself. any help would be appreciated. also, if i have to replace the front right channel amp, where can i get the parts for a good price?? any help would be appreciated. thanks
