If your television has RCA style audio/video output you can use an audio RCA cable (red & white connectors) and simply plug from the 'output' of your television into the auxilliary input on the back of the HT-BD2.

Then select AUX on the HT-BD2 remote, whenever you wish to listen to the television audio.

According to the instruction manual you turn off the unit and press the Stop button on main unit for at least 5 seconds. Didn't help me with my problem (shutting down for no apparent reason) maybe it will help you with your problem.
