G4 display cost

[becool773]

Hi,

Unfortunately today my G4(non-plus) fell down and the display is broken from the top. The rest of the screen and touch is fine. Is the screen covered under warranty? What is the cost of the display if we get it changed from the service centre and from the outside? Is their any major difference if the screen is replaced from a service centre vs local shops?

Kindly check the golden coloured circuit or whatever it is seen just under the speaker.

Thanks
