Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the Panasonic TVs; perhaps a TC-L37C22? ...not TC-L37CC22
Additionally, please describe how the Cisco DTA 271 HD boxes are connected to the TVs using what kind of cable(s).
