I connected my x1 cable box, PS4, and oppo disc player to 3 HDMI ports on the TV. Only the PS4 can display a picture. Both of the others say "no signal". I get the same result when I switch the inputs or HDMI cables. One curious thing is that if I disconnect the power from the cable box and then reconnect I can see the bienvenidos message....then after about 20 sec screen goes blank and I get the no signal message. Any thoughts because I can't find a TV setting that if changed makes a difference
adding.... did you use the same HDMI cable on each device?
