Nintendo Punch Out Arcade PCB Repair
About this video
Overcurrent damage to a Nintendo Punch-Out arcade board is narrowed to the audio amplifier circuit and an LA324 chip, with repairs to battery leakage damage as well.
Good to know: Battery residue is corrosive, and chip replacement means soldering: burns, fumes and lead in old solder.
Why watch it
Two kinds of damage share one board, from an overcurrent incident and from battery leakage. The maker also owns up to calling the chip an LN324 in the video when it is an LA324.
