Samsung code for a comcast cable box

The Remote w/ On Demand buttons, it's the same as the DVD player code 1932. Hit the AUX button, press and hold SETUP until AUX blinks and enter 1932. Press the power button and it should turn off the reciever.

*UNLOCKING VOLUME CONTROL* You must until your AUX volume control in order to use your Comcast remote. To do so, you must select AUX, press and hold SETUP until AUX blinks. Enter 9-9-3 and press Vol - (down). This should unlock your volume control when you select AUX. I'm not sure how to set AUX as your default setting for volume, unless you were to program your AUX device as your TV and vice versa I'd suspect.
Hope this helps!
