Toyota Ruifang central control does not display the weather

The Toyota Ruifang central control does not display the weather, which is a problem with the power supply system. If the signal output temperature is too low, many electronic components will not start. The operating temperature of the LCD is generally 0-50 degrees. At low temperatures, some capacitors cannot work properly and cannot be started, resulting in no signal output from the LCD. That is to say, when the weather is cold and the ambient temperature is too low, due to the characteristics of the display liquid crystal material, the vehicle LCD screen needs to be heated or the ambient temperature is raised to start normally.
