The LED lights on the phaser do not light up

If the lights on the phaser don't work, there are a couple of possible reasons. 

1) Check to see if the vest is powered on. You can do this by plugging in the phaser either in the chest module or the front of the phaser.

2) If the vest is powered on but you don't have LED lights on the phaser, it may be caused by a loose or pinched cable inside the phaser. A good indication is checking if the LCD screen is on or not. Open the phaser and make sure all of the cables are undamaged and plugged in correctly.

3) If you still aren't getting lights on the phaser, you need to replace the phaser mainboard. Please see the article on changing PC2056 if you need help.
