I'll bet that there was a nearby lightning strike that damaged the cable box and HDMI input. As the cable company fussed with things, the cable ground probably got disconnected. Most of the installers in my area don't see any point in that ground. Even if the ground was not deliberately disconnected, corrosion or accident may have eliminated the ground.
