Editing Atari 800 General Maintenance (section)

== Device-Specific Subsystems ==

=== RF Modulator ===
* The RF modulator contains small electrolytic capacitors that may fail, causing poor video or no output.
* If composite video is used, consider bypassing or recapping the modulator.

=== Cooling and Ventilation ===
* The Atari 800 has no internal fan but relies on passive airflow.
* Ensure vents are clear of dust and obstructions.
* For hot climates, consider adding a low-noise 5V fan powered from the regulator output.

=== Power Switch ===
* The mechanical power switch can oxidise or wear out.
* If the machine fails to power on, test continuity across the switch and clean or replace as needed.
