There is an installation where there is a few volts of difference between the system ground. The CATV shell and power-line ground on my TV are connected internally.
This causes a few amps to flow between the TV and the CATV line which causes visible moving horizontal bands on screen.
Signal strength isn't great, so I didn't want to add anything to the CATV line that would attenuate the singnal, so I connected every equipment connected to the TV behind an isolation transformer.
Is this the correct approach? How do you guys usually deal with this?
