Please melt each welding point again if it doesn't work. ?Pay attention to the positive and negative of the components.Make sure all components are in right direction and right place. ?The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components. ?It is strongly recommended to read the installation manual before starting installation!!!.
