Well, I seem to have botched my first attempt at backlighting a dmg screen. It appears that in the process of removing the old polarization film, I also removed another layer of the glass that I shouldn't have. I don't know, all I know, is that there's a slight rainbow effect on the bottom right corner of the screen. Regardless, all I get when turning on the screen is white dots.
So, I'm wanting to attempt it again, but I already went through the trouble of recapping the board, and would rather not do it again. So is it feasible to swap the screens? I'm guessing it's not... but I am handy with a soldering iron.
