Thread: high voltage readings on catv wiring

i am wondering if anyone has run into a problem with high votage readings on catv wires. i currently have a problem when i connect the catv wire to a television set i get a reading of 170 volts from the cable wire to either hot leg and if i disconnect the wire from the television i read 120 volts. i have never run into this problem and don't think it's normal. the cable company has told the customer that he has foreign voltages in the house and that is why it keeps burning up the catv connection outside.i was wondering if anyone has a solution too or a direction to start looking for this problem.

I have come across that before. I would guess it has to do with 1 or more of the converter boxes attached to the premise wiring. Possibly an amp that went bad. I am amassed that the CATVCO hooked his service back up knowing of the issue.
