When a chip dies, the symptoms look like a black screen, scrambled graphics, no sound or a machine that will not load games. A repairer first works out which chip is at fault with a meter or a scope, since lifting a chip that was never at fault puts pads and tracks at risk for nothing.
Console examples start with a Super Nintendo CPU or PPU repair, which sets out tips for telling them apart. A Commodore 64 with wild colours gets a colour RAM and PLA swap. On an arcade board, replacing a sound amplifier is a single-part job. For fault finding first, try diagnostics.
Taking chips off a board needs a hot iron or hot air, so expect burns and fumes, with lead in old solder. Heat can also lift pads. Use good airflow and let the board cool before handling it.
