It is unlikely that the display itself is faulty although it can happen. The typical problem is either the backlight is defective or the suply to the unit has a bad connection. If you can solder, try resoldering the pins on the display itself. The pins on the ends are the power and ground. I don't recall whether or not your model has a separate back light bulb or not. That too could be burned. Chack for that too.
Keep us posted,

The question is, do you hear any sound? Is just the display off or is the entire unit shutdown? Can you tell?
These displays are known to develope poor solder connections at the power input and ground pins. If you can solder, open up the unit (unplugged of course) and examine the pins for the display. This will be on the PC board attached to the front panel. The pins at either end of a long line of pins will be the power and ground pins. Reasolder those pins, taking care not to short the pins together and try the unit once done. If that does not resolve the problem (assuming it is just a display problem), update this with as many details as you can about the behavior of the unit and we'll look further.
