Restoring a Junk Game Boy with $3 AliExpress Chips. Power, LCD screen and Audio Fix.
About this video
Multimeter checks, treatment of battery leakage and a full recap are followed by chip swaps, including the IR3R40 audio amplifier, on a Game Boy DMG that began with no power, sound or picture.
Good to know: Battery residue is corrosive. Soldering and low-temperature alloy mean burns and fumes; old solder contains lead.
Why watch it
The replacement chips come from AliExpress, and the swaps use Chip Quik low-temperature alloy with a standard iron rather than hot air, which matters for anyone without a rework station.
