My ground wire for my cable is connected to ground wire coming from my breaker box when the tech tried to disconnect it it sparked and they would not reconnect. I checked ground wire with voltage and found some voltage present.

This occurs when there is an issue in the home wiring, could be a neutral to ground connection, could be a short circuit that has not gotten to level high enough to trip the breaker, or could be a normal ground fault current that comes from a refrigerator.

Does indicate that the grounding of the electrical system is questionable also.

I suggest you have an electrician come out and check the system and eliminate this current flow, and check the grounding system.
