Can you see the info working in the display and it is just the bulbs not working? Did you replace the bulbs only (not the sockets)? If so, make sure you have the bulbs seated correctly in the socket. It is a pain and a little off and they will not work. It is also easy to break the little wires off the end of the bulbs, and if that happens the bulb is no good. I think I also cleaned up the contact points on the back of the DIC with a scrotchbrite pad to make a better connection.
