An arcade board is a bare circuit board pulled from a cabinet, often forty years old. Typical faults are a dead boot, broken sprites and silent audio. The usual start is a look for corrosion, then a check of power rails and sockets, before any chip is touched.
Most of these videos suit readers who already solder. Paperboy with lines through the sprites is a narrower fault hunt. A board that will not start appears in Pole Position II failing to boot. The first part of a Nintendo Vs. series tours the board and explains it instead of repairing it, so it suits anyone planning ahead. Faulty chips are the subject of chip replacement.
A hot iron on a board this old burns, and the fumes need ventilation. Lead is in the old solder. Residue from a leaked board battery is corrosive, to skin as well as copper, so keep it off your hands. Powering a board for tests means a cabinet or bench supply with mains voltage inside.
