Hi, I have recently bought 55X8500C and so far its working great.
Amazed by the PQ and all the features.
However when watching YouTube I am getting the following message on screen "No Signal. Check the external input or select another input using the INPUT button."
So to sort out this issue I have to switch on the Set Top Box and select the correct input and only then this message goes away!
Does this mean that I always need to switch on the STB even to watch YouTube, and other online video apps? Rather absurd if this is true?
Does anyone else have the same issue or have a solution please?
