Greetings and welcome to Android Central!
Would this be for a DIY or you're intending to send it in for repair/replacement? If the latter, then while perusing the internet it varies according to locale and looks like anywhere from about $129USD ~ $245USD. I don't know if that is the prevailing $$$ these days or geographic specific but the chart posted shows July 2015.

Of course that's just from
one (1) online site.
I sure do hope you get your issue resolved and enjoy!
