Nebula Cosmos Max

My Cosmos max just stopped working, you know when an iPhone charger only works when you bend it a certain way? Well my Cosmos is like that now it only turns on when I bend the plug up and turns off when I bend it down I was just wondering if anyone knows how I could fix this.
Also it turns on if the plug is straight and sitting on a table but the second i life up the projector it immediately turns off, does anyone know how to fix this
