Hi Joe,
Welcome
A 2.0 I take it - the did not do a 1.0
Nothing on ICS! - Obvious one is the "dark" button which intentionally makes screen black if you want to reduce clutter when driving at night.
If not that then I would check fuses first. Is heating working? - If it is then possibly just a blown screen. Screen can be replaced on its own but probably easier to source a second hand unit.
Good luck
