OK, in what HDMI input of mini box is hooked the cable box?
is it HDMI-1, 2, 3 or 4?
Thanks, ***** ***** discuss it in text mode easily.
No, since TV shows no-signal-detected that means it has not selected on correct video input, so please press Source button on TV remote to get input source list and select the correct HDMI input where cable box is hooked in.
If it still doesn't get picture then reboot the cable box and reply back with the result.
