No signal when setting Cisco 9865hdc to Hitachi TV using HDMI cable
New customer to COX. Initial installation 11/12 was fine. Cisco 9865hdc hooked to Hitachi HDTV via hdmi cable. Picture and audio were fine. All was well until the afternoon of 11/13 when picture and audio went dark.
11/14 tech arrived with new box but was unable to establish connection with HDMI cable. Switched to second new hdmi cable...nothing. Tried all three HDMI tv ports...nothing. Verified that TV hdmi ports are functioning by successfully connecting other devices using hdmi cables. All work except the tv which must be connected with component cables to receive picture and audio from STB despite the fact that the initial install was fine.
What next is needed to connect Cisco 9865hdc to tv via HDMI or should another receiver be requested.

It is quite possible that the HDMI level coming out of the 9865HDC has dropped to a level too low for the Hitachi TV, or has failed completely. If you don't have a spare TV laying around (which might accept the existing HDMI level), the only thing you can do is replace the 9865HDC.
