Wow, so I told you what to do and even sent you links to the board...and you keep fishing... what else do you want to know???
Yes, you need to change that board to get the LED to light....and yes, you can do it your self!! It really is not that hard...
Not much more anyone can tell you...can't come through the computer and do it for you!!
Sorry if it sounded harsh...but this can get very frustrating when you get second guessed alot...no I'm not perfect, but I do try to give the best possible help that I can...
LOL... then you know the feeling...
Yes, repairs can be a bugger...especially when you don't do it everyday... be patient and check out the exploded views....and you'll be good...

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:
http://031d26d.namesecurehost.com/mwd/r630dka_dsa_dwa_sm.pdf
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.

so even though the display is working, just not lighting up sometimes (more often than not) I need to change out that board? is that something I can get at and do myself and is this something you have seen before on this model?

posted a while ago: Sharp microwave R-630DSA LED stopped working. It's an issue due to where it has to be located in the kitchen. I need to use a flashlight tipped off to the side in order to see the display... got a resp: "You will have to replace the power control board" I need to know: so even though the display is working, just not lighting up -sometimes- (more often than not) I need to change out that board? is that something I can get at and do myself and is this something you have seen before on this model? thanks to any1 who can help!
that was not necessary.. I just want to be clear before spending 100.00 on the board that it's only the function of the light that's the problem.. not the actual display... thanks for clearing that up and being really nice about it.... ????
thanks for that... I'm in tech support for a communications company and I try to be as clear as possible with customers/end users to avoid them coming back and saying I misled them or forced them to spend $$ when my suggestion was not the issue.. thats why I feel as though it's always good to clearify before accepting a fix.. I will order the part and do my best.. the door looks like it sucks to get open.. thanks for your assistance!
I got the information I need and I will order the part on line.. here's hoping!!! thanks guy!!
thanks man.. will do... funny.. if I didnt' like this Micorwave so much I should just replace it.. new ones dont cost 100.00..
