Hi there,
I have a Samsung LED TV with one HDMI port. I keep my set top box connected to the TV all the time. But, while watching TV, if there if a power cut, after the power comes back, the TV does not recognize the set top box which is connected to the TV, and shows "NO SIGNAL". However, It again detects the set top box when I do a power on/off from the switch.
I have replaced both HDMI cable and the set top box, but it's still the same... Please help...
