My android boxworked perfectly, the speed of response to the TV command was instantlyt. But after 2 hours of work, the HDMI signal stopped flowing to the TV, I restarted box several times and it started working, but without the HDMI CEC
HDMI CEC function Requires TV box, HDMI cable and monitor support CEC function to use CEC function normally. Please check if the requirement is reached. The HDMI cable supplied with the TV box does not support CEC function.
