Question about Sharp R-630D Microwave Oven
You will have to replace the power control board...
Posted on Mar 27, 2011
This is a common problem with LCD displays that are not connected to the cicuit boards by a sturdy connector. The displays in these microwave ovens are connected via a ribbon cable which is glued to the circuit board with special heat set electrical glue. They just tend to start to let go after some years of repeated heat and cold. You can fix this by following the instructions in the service manuel by taking the door apart. Once you have the ribbob cable exposed you can reheat each end of the cable where it connects to the display and the other end where it connects to the CPU board. Use a hair dryer on medium heat to get the connection area hot and then remove the heat and use something with a wide flat end like the adge of a credit card to press tightly against the end of the ribbon cable. This will restore the connection while the paste is soft. Hold it there for a minute or two while it cools. Be sure to do both ends of the cable.

Looks like your LED sheet isn't working
I forget the voltage that goes to that thing, but in theory if you don't want to spend a lot of money, you could probably fix this with a single jumbo LED (shaved flat on the sides) with a resistor on it for current control.
Basically, the LCD needs a backlight and yours is burned out.
If you aren't a do it yourself kind of person, http://www.microwavedisplay.com/ will give you details on having the unit repaired for about $40 (plus shipping) or you can order a replacement LCD unit (complete with LED sheet)
the service manual with part numbers is here:
the LED sheet is part number 5-13 under "door parts"
The manual also tells how to disassemble the unit if you're fixing it yourself.
