it could be a couple of things.
first thing to try, there should be a small button on the front of the radio or behind the faceplate, that says reset, use a needle or the tip of a pen, turn the car on, and press that button in for 10-15 seconds, if it works you will hear the cd mechanism start to spin
if not that you may have blown your accesory fuse, posibility why your other options arent working, look for the location of that fuse and pull it and replace it, even if it looks good it may be bad, wont hurt to replace it
you may have pinched a wire somewhere that you dont see, keep the deck wired up, and pull it out of the dash, if it works out of the dash you pinched something
lastly if none of those work you may have fried the deck somehow, take it back to where you bought it, tell them it doesnt work and exchange it for a new one
