2.Check your driver. There are two different kind of drivers, Constant voltage and constant current . check out put of your driver with volt meter to see if it show any output, if not, that means your driver is faulty.

4.check LED modules itself. Number of LEDs and the way LEDs got connected is really important. for example in series connection if one light fail all light will go off, so by finding the faild one and replacing that your light will come back on. most led chips has model number, so you can find the replacement or by checking the light specs you can find somethin similar in market. in this case you need to make sure to get something in same mili amp and same wattage
