Editing Atari 400 Capacitor Replacement Guide (section)

== Additional Tips ==

* '''Double-check polarity''' before soldering—reverse installation can damage the board.
* Use capacitors with equal or higher voltage ratings; never substitute lower-voltage parts.
* Clean any electrolyte residue thoroughly to prevent corrosion.
* If the video output remains noisy after recapping, check the RF modulator and its internal capacitors (if fitted).
* Store the Atari 400 in a dry environment and power it up periodically to keep capacitors healthy.
* Dispose of old capacitors at an approved electronics recycling centre.
