When I turn power on the Vizio TV, it does not see the HDMI input,
I own three Vizio televisions and two of them have recently developed the same problem. I use a universal cable remote that turns both the television and the cable box on at the same time. When that happens,the TV will display "no signal". However, if I turn the TV on, let it go through it's "power on" sequence and then turn on the cable box, no problem. The televisions have worked flawlessly for years until now. I have AT&T/DirecTV and the particular TV sets I have a problem with, the cable box has not been upgraded to my knowledge.
