Why do I have to refresh my Input on my 60 inch vizio tv every time .
Worked fine for a few months, then suddenly now when I power the tv on it is a black screen, no sound. If I change to another input, then back to tv input picture and sou d come on. I Have swapped the cable box and used a different hdmi input and still have the same problem.
