I'm working on a NDS Lite for a co-worker. Their kid dropped the DS, and now when you turn it on, the bottom screen only displays the color white. Other than that, the touchscreen and upper screen both work fine. I've taken the unit apart, removed and re-seated the bottom display connector but it's still doing the same thing. I don't see anything obviously wrong (broken solder connections on the display connector, etc) but I don't know where to go from here. Is it worth ordering another bottom LCD, or is it possible that something's broken on the main board? Thanks for any advice.
