I have came across a potentially serious bug with HDMI CEC on 1.1.0. Result: The PP Max will remain on with no fan cooling, the device will severely overheat and cause potential safety issues.
HDMI CEC is a protocol that allows you to command and control other HDMI devices, which is found in most home entertainment devices.
Steps to reproduce:
[Note: PP Max is on default settings]
Turn on PP Max with connected device already on [that supports CEC]. In my case, Apple TV 4K.
When the Apple TV 4K goes to sleep, the PP Max will go to sleep as well.
When attempting to turn on the PP Max, the No Signal screen will show, but the PPMax fan cooling will not be on. Device will be extremely hot to touch.
The device will appear to remain functioning correctly [ navigation on the Android interface ], but the device cooling system is completely remain off.
Go to hidden settings menu -> Input. Disable both HDMI control and TV auto power on. Both options are turned on by default
I personally do not use HDMI CEC. The function appears to be broken on the PP Max and should be disabled by default.
The fact that the device remains on and overheat shows that there might not be a safety thermal threshold to allow the device to shutdown in event of a cooling failure, or it might have one that is not kicking in when needed.
With most home entertainment devices with HDMI CEC enabled by default, this might create a potential hazardous situation if the abovementioned scenario were to occur.
