Re: voltage in cable coaxial
Not a chance I would agree with that.

There is no way UL would allow this to be a safe normal condition.
50 or 60 volts is a fair charge and if there is 5 ma or more this potentionally can kill.
The caps from the power supply don't normally feed back through the circuitry on a 2 conductor power cord.
If you had 50 or 60 volts feeding back through the tuner block I doubt the TV would be working or not very well at least.
Back in the day when electronic equipment used tubes instead of solid state components .... then maybe you might find feed back voltages . The metal chassis were notorious for being hot for grid voltages..... this is not the way it is with solid state componets used for over 35 years.
If there is voltage on the CATV cable coming into the home then it's the cable company's issue ...... either problems with the distribution amps or from their plant.
If the cable shows clean coming to the house but shows a voltage on the cable in the home then there is a ground issue .... perhaps the cable company ground block or grounding issues within the home.
If there is a cable box involved and the cable coming into the box is clean but has voltage coming out .... it's the cable box.
If there is only voltage coming out of the TV .... the TV is faulty.
