== Recapping Procedure == # '''Disassemble''' – Remove six case screws, slide keyboard forward, lift the RF shield. # '''Label cables''' – Photos help when reconnecting the power-LED & keyboard flex. # '''Desolder caps cleanly''' using a temperature-controlled iron & braid / pump; apply gentle upward pressure only after all solder is molten to avoid lifting pads (VIC-20 traces are thin). # '''Install new capacitors''' – observe polarity: the striped/- side to ground. Lead-spacing on main filters is 5 mm; modern 8 mm diameter caps fit without bending. # '''Inspect & wash''' – Flux residue is mildly conductive; scrub with 99 % IPA and a soft brush. # '''Re-form (optional)''' – Bring the board up on a bench supply through a 1 Ω resistor for the first 30 s to reform large cans gently.
