The screen is black. Tried to do soft rest did not work.

Was working fine. about a month ago it started working and not working intermediately. then just stopped The screen does seem like it tries to come on for a second then goes right off. So no music, no GPS, no backup camera, no heat controls. NOTHING. It is a pain in my ass. Tried to do a soft rest that did not work. Can't see the screen to do a hard rest. Just got this car about 5 months ago. Don't want to spend and arm and a leg to get this fixed.
