Here is my setup:
My current behavior is the Apple TV can turn on the TV and it will set the input correctly, so the Apple TV will display. However, I cannot turn off the TV when I turn off the Apple TV from the Apple TV menu (Sleep now / Sleep All Connected Devices). With a different TV (Insignia 32" HDTV) the Apple TV can turn off and on the TV properly with no issues, so I doubt the cable or Apple TV is a problem, it just seems like the issue is on the TCL.
Has anyone else experienced this problem?
I've done some investigating and since the TV is an Android TV, you can enable Developer Options and you can connect the adb to view logs to see if anything abnormal is happening when the Apple TV is performing the turn off all connected devices. Here is the log output when "sleeping" the Apple TV and connected devices. Basically it seems like the HDMI CEC implementation is not working.

UPDATE 1:
I called TCL Support and told them about this issue, but they didn't have a solution. I installed cec-client on a Raspberry Pi and I was able to verify that the Apple TV is definitely sending the correct standby broadcast message. But again the TCL is just failing to handle that broadcast message. I am not sure if this a common problem with other Android TVs, but it appears that Android TV OS has the correct HDMI classes, but my guess it's also up to the TV manufacturer to implement and respect the HDMI-CEC messages.
I created a solution using a Raspberry Pi which will listen for the broadcast message using HDMI-CEC and send a standby command using adb (Android Debug Bridge). If you're interested in using it, please go to https://github.com/paulsaccount/hdmi_cec_to_adb. Setup instructions on the README.md document.
Hey, I have an old Philips TV (https://www.philips.ro/c-p/32PFL5322_10/flat-tv-digital-panoramic-cu-pixel-plus-hd) and I was thinking of making it smarter with a Xiaomi MI TV Stick which is basically a Android TV stick. But I am afraid that the image will look bad because this is not a full HD TV. I see in the specs that it supports 1080p video formats but I don't know what that really means. Can you guys help me?
Thx a bunch!
I need remap primarily for Enter key to DPAD_CENTER key. Two working solutions, but they come at the cost of on-screen keyboard.
Solution 1
Solution2
I looked at this XDA thread, but it needs root. Kindly let me know if there's a solution that doesn't require root.
I can avoid this headache by buying OEM Nvidia Shield remote, but our infant destroys remotes every couple of months. So, buying cheap remotes for 10 - 12$ and then remap.
Update
Bought G30 remote from Amazon, and it solved all my use-cases perfectly. Only pain-point is that buttons are too closely placed, and it's nearly impossible to push any button correctly in panic mode. Placed an order for another remote for spare.
