Gray screen with vertical moving bands at time. External monitor is fine. Device manager claims display is working. Can I replace lid or screen and get the display back?
 
If external monitor works okay, that means the laptop's graphics processor is okay, so it must be either the screen or the inverter which need replacing. I don't know enough about them to say which of those two has failed with confidence, but from your description I'd say it's the inverter.
