Exact same issue with HW-K450 - tried troubleshooting 3 times now with Samsung support, 1 chat, 2 telephone sessions (almost 40 minsutes each). Finally got it to work. Once. Went right back to same behavior: 1. TV turns on, Sounbar turns on 2. TV off, soundbar off. 3. Approximately 10-20 seconds, soundbar comes on, does not find TVCONNECT, shuts off. 4. Turn on TV, soundbar soes not turn on. 5. Turn soundbar on with remote, immediately connects to TV via TVCONNECT. Reset everything possible except for TV. I am going to try and escalate this in support - TV and soundbar are 2 years, 3 months old. Also, one of the replies refers to the latest firmware updates - I am going to see if I can find out when my last update was and if that date correlates to the start of the problem.
