Fix for Powering ON the TCL Android TV from Google Assistant or Google Home and other similar devices.

Such a first world problem but I could only power off my TCL 65 X7 and not power on , annoying as hell, because afterwards I just could use any phone to act as Android Remote, or just cast YouTube/Spotify from my Lenovo Smart Clock. Here is how to do it.

1. Turn On Network Standby : Settings > Bottom of Network Settings

2. Turn On Developer Mode : Settings > About > Build Number > Press OK several times until TV prompts you being few steps away from developer.

3. Turn On Never Sleep while Charging. (Cannot Verify the effectiveness of 2 & 3)

4. Disable Device Sleep : Settings > Screensaver > Put Device to Sleep > Off

5. Go to Secret TCL Settings Menu : On your Non-Smart Remote > Settings Button > Picture Settings > Advanced Settings > While Contrast is highlighted,

Press the Numbers 1, 9, 5, 0

Do not open Contrast

Settings > Main Menu (Service Menu).

Here if you mess up anything just perform NVM Reset to set default values.

Up/Down Arrow Keys to Select Options. Right/Left Arrow Keys to Change. Menu (Hamburger) Button to go back. Back Key to exit.

5a. Factory Menu > Power Mode > Change From "Standby" to "Last" or "ON".

Go Back and Reboot. Also reboot your Google Home or Google Assistant device.

(Tip: If you get stuck somewhere at something like "P" verbose logging, your remote will stop functioning, Press the "OK or Power" button on TV itself to go back,

Also unlike some tips on Internet, you can use LAN for TV for the power on function to work, no need to change to WLAN only : Just extra latency for 4K streaming.)
