Editing Atari Stacy Capacitor Replacement Guide (section)

== Capacitor replacement procedure ==

# '''Disconnect AC adapter and allow to sit for several minutes''' — No mains-voltage components inside (external PSU), but allow any residual charge to dissipate.
# '''Open the case''' — Remove bottom screws, separate case halves carefully.
# '''Photograph the board''' — Record capacitor orientations and locations before beginning.
# '''Remove old capacitors''' — Heat each lead and use desoldering pump or wick. For stubborn joints, add fresh solder first to improve thermal transfer.
# '''Clean pads''' — Remove residual solder and any leaked electrolyte with IPA.
# '''Install replacements''' — Observe '''correct polarity''' (negative stripe on capacitor body aligns with negative pad marking). Insert leads, solder, and trim.
# '''Inspect solder joints''' — Check for bridges, cold joints, and correct polarity under magnification.
# '''Test for shorts''' — Use multimeter to check for shorts between power rails and ground before powering on.
# '''Power up and test''' — Connect AC adapter. Verify voltage rails. Boot the system and test all functions.
