My Onkyo HT-S3300 worked flawlessly for nearly two years. Until yesterday.
I unplugged the receiver in order to free up an outlet for Christmas decorations (yes, it was on standby), and when I plugged it back in and turned it on, the Dolby D setting was completely messed up. For example, while watching a football game, I can hear the crowd and the action on the field but get no vocals from the game announcers. If I set it to "all channel stereo" I can get everything, but at "Dolby D" it's only surround sound. On some stations it works fine on Dolby D, but the commercials have the same effect as the football games.
Also, I tried to play a movie off my USB drive, but the only sound I got was from the front surround speakers, and it was very faint.
Thanks in advance for any help.
