I just had this problem occur after I was fiddling with my sound connections (trying to connect headphones- IMPOSSIBLE!). I have soundbar model HW-F550 connected to TV model PN51F8500AFXZA (2013). I have HDMI cables from cable box to HDMI IN on soundbar, and HDMI OUT from soundbar to the TV's HDMI IN. I also have an optical DT audio cable running from the TV's OUT to the soundbar. Everything worked fine before: when I powered on the TV + cable box, the soundbar would power on, show "D.IN" briefly and then switch to "TV ARC" all by itself. Suddenly, powering on did not start the soundbar. I had to manually power on the soundbar and manually switch to D.IN. Then the soundbar would switch to TV ARC.
I did solve the problem! Perusing the soundbar manual, I found instructions to push a button on the soundbar remote: "Auto Power." However, I then got message on the soundbar that this function is "unavailable with AnyNet+ turned on." So I tried fiddling with the AnyNet button on the remote, and after switching the input away from D.IN, I was finally able to turn AnyNet+ off. I was then able to toggle the Auto Power button and get an "Auto Power ON" message. Finally, I turned AnyNet+ back on. Turned everything off, and the system powered up as before, with soundbar starting automatically, and switching from D.IN to TV ARC as before.
Hope this helps in some cases.
I'm not sure whether this is too late for an answer. But mine is connected via optical cable. It suddenly started doing the same thing. Slightly different models. But really hope this works for you all... 😔
Once Universal Remote is setup and everything is SWITCHED ON, do the steps below:
- Check whether ANYNET is OFF on the soundbar (the button is on the bottom right next to WOOFER button on the soundbar remote).
- Switch off everything using appropriate remotes.
- Switch on the TV using the universal remote.
- It worked for me.
GOOD LUCK GUYS!!!
Hi our sound bar keeps disconnecting from our Samsung tv. We had taken it back a number of times and they could find no fault. So after buying another more up to date one just a week ago it's doing excalty the same thing. We now believe it is a fault with the tv as this isn't just a coincidence. Also we are using a HDMI cable and still this happens any ideas as to why this is happening. 😀😀
