It sounds like you probably have a broken optical cable. Optical cables are made of glass and are quite fragile. You have to be very carefull to not bend it or smash it. Try connecting another optical cable, or you can also revert back to the stereo analog plugs to eleminate the possibilty of having a bad receiver.
You shouldn't connect the subwoofer to the TV. Just connect the Right and Left audio cables (red and white RCA plugs) to the TV audio out and then the other side goes receiver's audio in. If you are using the subwoofer that came with the unit, connect it to the sub port (purple and grey or black striped). The red and black striped cable goes to the subwoofer control.
If you are using another active subwoofer, connect it to the RCA jack labeled Subwoofer Audio OUT.
If you have a 3-plug RCA cable that is a composite video cable. The yellow plug carries the video, the red and white carry the audio signal. This cable is most often used for connecting older VCRs and game systems to a TV (or newer devices to an older TV). Thus leave the yellow jack dangling if using it for an audio cable.
Set your TV to use the external audio speakers and the receiver will take care of the signal to the subwoofer. (You only would connect the speakers individually for a computer sound system.)
Well, I just returned the unit. RCA replied with the following solution: Let the unit sit with the AC power cord out of the wall for a couple of hours. Then hit the power button 10-15 times (with the AC power cord still out of the wall socket!) and then try again.
have you checked to see if any of your speakers are shorted out? the rt2870does have a self protection system in place such that if theres too much power being drawn from the system or if a short occurs it will shut off. or the switch that powers the sub may have gone bad so try disconnecting the sub and see if that helps. i have the same system and i had the same problem and i had to replace the onboard sub-woofer power switch.
