In 1989... 31 years ago... Nintendo released the GAMEBOY. It was my favorite and only requested Christmas present that year. Recently I searched other youtube videos and found out that repairing the vertical line problem on the original DMG (DOT MATRIX GAME) was fairly easy and decided to give it a go for myself and share the results!
With a bit of patience and a soldering iron i was able to repair my old unit to it's original condition!! Check it out.
