Editing Atari 800XL Capacitor Replacement Guide (section)

== Capacitor Replacement Procedure ==

# '''Disassemble''' – Remove the five case screws (three rear, two front), gently lift the top cover, and unplug the keyboard and mylar flex cable.
# '''Remove RF shield''' – Desolder or carefully unclip the metal shield. Note that some shields are soldered at multiple points.
# '''Label all connectors''' – Photograph or label SIO, power, and video leads for correct reassembly.
# '''Desolder capacitors''' – Use solder wick or a spring pump. Atari used robust, high-melting-point solder; set iron to at least '''350–375 °C'''.
# '''Install replacements''' – Match '''polarity''' (long lead = +), and use correct lead spacing (2.5 mm or 5 mm depending on position). Keep new capacitors under 13 mm tall to clear the shield.
# '''Clean up''' – Remove flux residue with IPA and inspect for solder bridges.
# '''Reassemble and test''' – Refit the shield and keyboard, then power up.
