Hi, my name is ***** ***** I will do my best to help you today. To make sure I don’t miss anything, please give me a minute to review your question.
- Have you tried to unplug TV, DVD and Sky box power cords from wall outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?If not yet, please try it now and reply back with the result.
This is odd, is there any other video source available to try into HDMI input of TV?
This way we will confirm HDMI inputs of TV.
OK, let me repost the question for other experts to have a look into.
