If the ground wire for the house power is loose, then the cable tv line is carrying some the current from the house's breaker panel (the amount depends on how much of an unbalance there is between circuits at the moment) back to the pole. Usually, the power poles have a very good ground on them (bare copper wire spiralled all around the pole and on it's base, underground) and CATV is grounded to that. So, a bad ground at your house means the excess current will flow toward the pole, via whatever means is connected....Cable TV shield, phone wire, etc.
Be very careful fixing it, or call an electrician to fix it. Either way, it needs repair.
