I have a HK-650 sound bar which I have to run the Sky through as my TV doesn't have bluetooth. It has frequent problems, the sound cuts out, the picture on the TV gets a pink tinge & the sound cuts out, the picture goes blue & I get an error that says "this screen does not support HDCP". Various fixes resolve the issues, usually turning off\on the sound bar fixes most, if not then repowering off the TV, Sky & soundbar, and if that fails then reconnecting the HDMI cable will sort it. This is usually an everyday occurance - not what I signed up for when I purchased my soundbar! The TV is a samsung ue46f5500ak.
