I have a gfci on one circuit that trips when I turn on a tv that is on

This only happens if I leave the tv off for exended period of time like 24

hours!



I can not repeat this if I simply turn the tv off and on repaleatedly!

And when I leave the

Tv off for 20 hours or so it does not always cause the gfci on the

different circuit to trip!



I replaced the tripping gfci with a new one and it changed nothing.



Also in heavy rain the tripping gfci does trip! It is a circuit with long

runs to outside lights and shed!





Also tripping gfci was once a circuit that had RF on it! This is 1940 BX

wiring!

What does "once had RF on it mean"?
