Question about Rotel Audio Players & Recorders
Turn off the other channel and listen only to the bad channel playing some music. Turn it up! If you hear any music the pre-amp is working and the power amp is faulty. If you don't, then the pre-amp is faulty.
Because it's a stereo amp you have the good channel to compare with the bad. So you can do voltage tests, or "buzz" tests. Buzz Tests or where you apply a insulated tool to the circuits, a buzz will be heard. If it buzzers in the good channel it should in the bad. Ignore the power supply and don't short any parts out!

all of the channel are resonding to the test. but you cant notice it bec 5.1 speakers, each channel are designed to respond to a certain frequecies. the L/R channel your talking about have the mid-range frequecies so it responds clearly compared to other channels...
hope that helps...
