Hi. At 72 years old I am technically impaired. Please help. My tv is set to HDMI2 which has been working perfectly up to now.

Now tv shows DVI and has no sound. Happened a week ago but when resetting the main decoder everything was fine. Now when switching tv on there is once again no sound. I have extraview dstv and mine is the 2nd tv. Changing to HDMI1 (whichis the main tv) shows"no signal"

What is plugged into those connections? There maybe be a selection in the options to set what the HDMI port is for, it's often used with computers to help with image issues. See if you can change the HDMI port settings back to standard HDMI.
