Re: Sound bar turning on by itself

This sounds like a Simplink problem. There's potentially an issue with the signal coming from the TV causing the soundbar to think it's on. I understand that you'd typically want this feature on but if the soundbar is randomly turning on, a temporary measure would be to turn the AutoPower feature off like tonysix00 said. In the meantime, I would recommend checking firmware updates and contacting the manufactur of both the TV and the soundbar. Since OP mentioned it didn't happen on the previous TV I'm pretty sure the offender here is the TV.

Re: Sound bar turning on by itself

Hello Tmaxx,

 

Welcome to our community! I’m sorry to hear that you’re being plagued by a similar soundbar related issue.

 

As noted in the post by @GS_Storey at this time it may be best to disable the AutoPower feature, and contact the manfucturer’s of your TV and soundbar after double checking your firmware is up-to-date. We haven’t been able to determine clearer solution, but appreciate any further insight you can share regarding your issue or troubleshooting steps you’ve tried.

 

Kindly,

Re: Sound bar turning on by itself

Hello, 

I have experienced a similar issue, and while I haven't come up with a solution, I have an explanation.  For my sound bar, I had an LG SJ9 (entry price point Soundbar) using with a non-smart LG TV with NO AUDIO OUT connections.  As such, in order to get my soundbar to work, I needed to connect the optical cable to the back of my Comcast cable box.  It worked like a charm, until it started turning my TV on in the middle of the night at 4 am.  Reason is, this is when Comcast sends it's nightly firmware update.  After it completes, it resets the cable box, off and back on.  When it turns back on, the TV also thinks it needs to turn back on too...   Made for some surprising wakeups in the middle of the night!!   This is evidently related to HDMI CeC technology meant to allow one device to turn on another device.   (So we can use the comcast remote to control both our TV, sound bar and cable box).   Potential FIX:  Turn off the HDMI CeC feature on the TV (All manufacturers typically call it something different (Simlink, etc..).  Problem is, then you won't be able to use the remote for both devices...     Alternative solution: 1) Get a universal remote that sends separate signals to each device, and disable the HDMI CeC feature.   Option 2) Change the update time that Comcast updates the firmware each night. I set it to 8 a.m.  It might still turn my TV on, but at least it's not in the middle of the night!  3) Get a soundbar and TV that can connect without connecting to the cable box.  (Either wirelessly, or through traditional audio connection.)   Hope this helps -- You situation might not be the exact same, but if your TV is turning on by itself, it's probably related to HDMI CeC.
