How to fix radio in Jeep Wrangler

I have a 2017 Jeep Wrangler. I have the touch
screen radio in it and a few days ago the
screen starting glitching then the next day it
completely stopped working no music or
anything but the buttons on the side of the
radio still light up. Every few minutes the
buttons on the side with flicker out and it will
make a weird sound( sounds like a fuse has
blow Everytime it does it) my boyfriend took
the whole thing apart and couldn’t figure it out
but when he put it all back together ( so it
wasn’t ripped apart until I could purchase a
new one) the radio just started working
again.It only started working for a few hours
and now it’s back to not working at all expect
the lights on the side are still lit up. Does
anyone have any ideas before I purchase a
new one which will cost 680$ plus tax from
the dealer.
