Anyone ever repair a 3ds xl? if so, my problem is both screens backlight but do not display. I replace the top lcd like 5 different ones(I keep ripping the d*** ribbon) and nothing. Now prior to me replacing the top screen, the bottom touch screen lcd was working and after I replace the top lcd the bottom didn't come on. After painstakingly making sure the ribbon connector are connected to the mother board it still I got this.. . Could it be the the bottom lcd causing all of this???
