How to Troubleshoot & Replace Lg AP5017310 / EBR42479207 Display Power Control Board Assembly

Half of the LED numbers displaying the freezer and fridge temps were burned out. The part arrived quickly and replacing the old display board was a snap. I'm just a homeowner, not an appliance pro. But this repair was a breeze. 

Ordered this part (saved almost $100 off the manufacturer's price). Used a screwdriver and butter knife to loosen edges of control board and ice/water dispenser part. Pulled out connections from old part. Unscrewed 9 screws to take out whole part and slightly bigger part on top. Put in new part and redid new connections, screwed in screws and pushed whole dispenser/board piece back into fridge until it snapped. I did this with my male friend, as I am a female. I probably could have figured out how to do this with the help of previous answers, but it would have taken me much longer. My male friend held the dispenser part for me and I did the screws and connections part. He helped me with some connectors. He made the repair go faster and easier (about 40 minutes from start to finish)! 

Once I got the ice/water/control module out the repair was easy. The part provided was an exact match and as usual I took a picture of the wiring prior to removing the old board which made It easy to wire in the new one. The module was a bear to get out and you are worried if you pull too hard you might break the plastic but once I decided it was coming out and gave it a good pull it snapped out. I now have a solid place to get my LG parts.
