Garbled sound with my new Roku when disconnecting cable TV box
I just got a Roku wanting to get rid of my Xfinity TV service. When disconnecting the cable TV box I lost my picture and got a list of instructions. So plugged back in and turned off the Roku and TV while disconnecting. Ok that worked. Then I unplugged the cable coming from the splitter with Roku & TV turned off. When I turned it back on the audio was garbled. So I hooked the cable back up to the TV box which got rid of the garbled audio. There is no power to the TV box.... I don't know what to try next.
