I just bought a 07 Base TL and the screen wont turn on, so i cant see which radio station im on or the temperature, does anyone know why it doesn’t turn on?

 

How haven't given us much to work with. What have you done so far in term of diagnosing yourself? Have you checked connections, fuses, relays????

 

there are a lot of details missing, but i'll try my best to help

sounds like its not a navigation screen, sounds like it's base model split display (radio and hvac)? please confirm.
by reading a recent thread; I learned that aftermarket harnesses can cause this issue...or an unplugged harness can cause this issue.

if you're daring enough, take apart the center console to see if it's an unplugged harness.

or you could just take it back to whoever you bought it from and ask them to help you diagnose and fix
