Your post is lacking information. You are talking about the Radio correct? you say you have checked the fuses. Have you specifically REPLACED the fuse for the radio with a NEW fuse? Start there. It may look OK, but replace it. they are cheap.
If a fuse replacement doesn't do it, then the radio may have gotten fried. you could take it to a local electronics place and see it they can figure it out. a cable or wiring harness may have gotten shook loose (unlikely) or the radio could have fried the display (more believable) A new radio may be in your future.
