If you disconnect the receiver from power, then press and hold the bind button while plugging it in, does the LED come on at all or start flashing? It should either be flashing (fast or slowly), or it should be constantly lit. There should be no situation where the receiver is plugged into power and there is no LED on at all. If you're getting no solid or flashing LED on the receiver then I think you have a problem with the receiver itself. Your wiring and Betaflight settings look correct.
