Hi, I have just bought a Samsung UE50NU7400 50ins. 4k smart tv. I am having problems pairing my Sky remote to the tv. Sky's website say that the code is 2079. My Sky remote is SKY HD rev.9f. I have gone through the procedure, but it does not work. Also, I cannot seem to find any settings on the tv to adjust brightness, contrast, colour etc. I would be grateful for any help. Regards.
