{{Main|Atari 2600 Capacitor Replacement Guide}}

Critical capacitors requiring replacement on all models include the main 2200µF 16V filter capacitor and multiple 4.7µF bypass capacitors. The 6-switch models additionally require replacement of C103/C104 (0.22µF) near the voltage regulator to eliminate video artifacts. Styrene capacitors C206/C207 (6-switch) or C53/C54 (Jr.) commonly fail and cause audio loss. The 7805 voltage regulator should be upgraded from the original 0.5A rated part to a 1A version during any capacitor replacement.
