How to connect Bose Cinemate Digital Home Theater System to a 740 WD-82CB1 Series Mitsubishi Home CINEMA Television?
The TV uses a "Coaxial" Digital Audio Output jack to send it's Audio signal out to external devices. The Bose is a strictly analog set of powered speakers. The workaround is that you need to purchase a Digital to Analog Audio Converter, which would connect via a single RCA cable to the TV's "Digital Output" jack, and will convert the signal to standard RCA. From there, you would use RCA cables from the converter to the Bose system. The link to the converter you'd need is below:

Are you using an HDMI cable to connect your cable box to your TV or some other connection?
