Ground Loop Issue
Cogeco just hooked up my Tivo and as soon as they connected the receiver I get a loud buzz (ground loop) from my 60,000.00 system. This is the first time I have had Cogeco TV and have not had ground loop problems with any other equipment. They tried two boxes and both create the hum, any idea if it is my responsibility to fix it or Cogeco's? I would like to get Cogeco as it is my only way to get 4k and nobody I have talked to at Cogeco (6 people now) even know what a ground loop is.
