I got a DMG gameboy with a few problems, but i managed to fix most of them cleaning and resoldering some points on the PCB. But the screen still has a dead vertical line.
And i have to say: the original screen is fucking terrible. Like its only acceptable from a nostalgic value, because you cant see shit on it.
My problem is that not only if you want to replace the screen, you also have to replace the power board, and those 2 things are above 60-70USD together. And i will be stuck only to play GB games. Damn.
