A month or 2 ago I bought a Galaxy New Nintendo 3D XL in hopes of fixing it, upon opening it I found some corrosion on one of the ribbon connectors and the ribbons themselves, I used ethanol alcohol(Not the right kind, I know but it's the only one I had on me at the time) to get as much of it off and I was not able to get it to turn it on, it would lit up with a red light, a pop sound would be heard and then it would turn off again. Fast forward to last night and I finally got a microscope and upon looking at the ribbon connector under the camera I noticed that the solder on the ribbon connector was missing. My question is what I would need to repair it, if it is repairable? Any help is greatly appreciated!
