Roku setup

[tubesmuggler]

Hey folks, hoping for some help.  My system is pretty simple:

roku ultra 4640x

Samsung tv 55HU7250 (2015?)

Onkyo SR393 (2020?)

In late 2020 I set this system up.  Connected receiver's ARC output to TV's HDMI (STB) input.  The Roku Ultra HDMI to the receiver's "Streambox" input. I used the Roku remote "home" button to power on the TV and receiver.  The old 4640X remote does not have IR so I assume there is some type of sleep/awake thing going on that tells the receiver to turn on, which turns on the TV, but I really don't understand. Then to power off, I simply went to the "TV Off" tile on my list of channels.  This turned off the TV and receiver together.  A thing of beauty!!!

This worked great for nearly 3 years but somehow stopped a few months ago and I haven't been able to figure out the issue.  Now, when I click the home button on the Roku remote, the Ultra receiver LED flashes as usual but only the receiver turns on.  I have to use the Samsung TV remote to turn on the TV.  When I want to power off the system now, the "TV Off" tile just makes a "ba-boop" sound and nothing happens at all.  I use the Samsung TV remote to power the TV off, and the receiver turns off then too.  Also, the TV remote will turn on the receiver along with the TV if I haven't already used the Roku remote first.

To make things even worse, a few weeks ago the receiver now usually turns from the "Streambox" input it's is ALWAYS set to, to "TV" within about a minute of being powered on.  So now I need a third remote (the Onkyo receiver remote) to switch it back to Streambox setting to view the Roku.

I'm hoping for some help, thanks!

You probably want to go to each device and make sure HDMI-CEC is properly set.  On the Roku, you need to make sure that “1-touch play” is enabled. On the other two devices, you’ll need to check their settings.  Funny thing about HDMI-CEC is that lots of companies like to use their own names for it.  Samsung’s name is Anynet+. Make sure it’s enabled everywhere and look for anything like “Refresh the network” on each device, and do that.

Thanks for your reply!  The CEC settings are "on" for the receiver and TV.  The TV remote turns on/off the TV and receiver as would be expected.  The Roku does have 1-touch play enabled.  Perhaps there was a Roku update that caused this to fail?  A few weeks ago I did a full reset on the Roku but no change.  Maybe I need to do a full TV reset next. I haven't seen any refresh options on the TV.

Sometimes you just need to unplug the power from everything for several seconds and then plug everything back in.

OK looks like it's back to normal.  Too bad I didn't learn this earlier, but yes, unplugging the TV and waiting about 5min did the trick.  Everything is back to normal:  Roku remote turns TV and receiver on, and the "TV Off" tile turns them off.  Perfect!

Hoping this fix lasts.  I was reading on the Samsung TV forum that some folks are doing this nearly daily...

Thanks again folks.
