Is this a visual issue or a functional issue? Because the name that shows on an Onkyo front can be any name. For example, I renamed whatever jack my AppleTV is connected to on my Onkyo, and AppleTV is what shows when I turn things on. If watching things on AppleTV works but it's only showing an unexpected source NAME on the front, go through settings and find where things are named and rename it.
If it is a
functional issue, my first guess is that you have SOMETHING else connected to that Blu Ray input that is on, always on, or perhaps reacts to AppleTV "on" to then "fool" CEC processing into thinking you want to use it instead of the other(?) AppleTV input, so it "inherits" control by reacting to AppleTV on + Receiver on + TV on. If there's potential here, unhook whatever is connected to that jack and try turning on AppleTV with AppleTV remote again and see if it works normally. THEN, to verify this might be it, plug whatever it was into a DIFFERENT HDMI port on Onkyo, then try turning on again and see if some other port becomes the one connected. If so, that other device needs some investigation.
Now mix the 2 above: you MIGHT have something misbehaving hooked to another port and that port has been renamed/redirected to display as Blu Ray. If this is a possibility, unhook all other HDMI connections to that Onkyo except AppleTV into whatever port is connected now and TV on the HDMI OUT TO TV jack. Then try turning it all on with AppleTV and that should work. If not, I fully suspect something wrong with Onkyo.
From time to time, my Onkyo seems to get wonky in a few select functions... particularly airplay connections. A remedy that "fixes" it
every time is unplug Onkyo, wait about 30 seconds, plug it back in and try again. If you haven't done that for a while, that's a very EASY thing to try and might resolve all issues without unhooking anything.
While CEC generally works pretty well, it is a black box technology. You can't easily monitor what is happening and debug. I got to a point with it that I got frustrated and turned it all off, switched to using what is called a "Learn Remote with Macros" programmed it to do CEC things and now it runs the CEC show (with CEC off). If you don't find your way to a remedy through some process of elimination, this is a "for sure" option by basically "firing" CEC and replicating it in a Learn remote with Macros:
- Learn learns each component in your mix
- Macros executes connections and input selection.
Each "mode" or "source" has a dedicated button called "setup" associated with it. So anyone in my household can choose what source they want (one click of the remote) then click setup and it will get the various parts active to make it work. For example, I want to watch a Blu Ray. Choose Blu Ray source, then click "setup" button. A macro tied to setup knows Blu Ray is connected to a specific HDMI port on the Onkyo so it selects that input. If I then decide I want cable, select "Cable" mode, then setup. If AppleTV, select AppleTV, then setup. Each "setup" push executes a macro to get the pieces set up properly and then the remote buttons manage the chosen source.
In general, this is how CEC is supposed to work too (no programming) but CEC may or may not work and you can't easily tell why it's not working when it doesn't.
