I cant find an answer. I live in ny and have Time warner cable, an older box, pioneer. And a rf modulator for the dvd, its all connected. After a month the cable box does not work. Could it be a rf mod? I try to unplug the modulator when im not using it. Still had the problem, had to change the box once, currnet box is having problems. Cable company doesnt have an answer. Could the modulator be sending a signal to the box?
