My Blaupunkt car cd player, the screen lights are off. They blink some?

My Blaupunkt cd player has gone black. No lights on the screen. I think it is a connection problem because they sometimes blink on and off when the road is bumpy. I have pushed and wiggled the faceplate but no luck. It is only 2 years old. The company could not help me. Any suggestions on how to correct this? It has a nice sound. Blaupunkt San Diego model.
