''Find the '''board code''' silkscreened near the cartridge slot or on the PCB edge.''

== 🧼 Regular Cleaning ==
=== Case & Controller Ports ===
* Wipe exterior ABS plastic with a '''damp microfiber cloth and mild dish soap'''.
* For yellowed cases, use '''retrobright''' cautiously—avoid overheating and UV overexposure.
* Clean controller ports with a soft brush and 99% isopropyl alcohol (IPA).

=== Cartridge Slot & Expansion Port ===
* Use a '''dry, clean cartridge''' to gently exercise the slot.
* For stubborn contacts, insert a thin card wrapped in IPA-dampened cloth.
* Clean the expansion port (underside) with compressed air and a soft brush.

=== PCB Dust & Corrosion ===
* Unplug the console and wait 5 minutes for capacitors to discharge.
* Blow away dust with compressed air; brush gently with an antistatic brush.
* Inspect for green/white corrosion near capacitors and battery.

== 🔋 Power Supply & Battery ==
* Only use an '''original or high-quality modern replacement PSU''' (9–10V DC, center-negative, 850–1200mA).
* Avoid cheap, unregulated adapters—these can cause '''overvoltage''' and damage.
* If your SNES has a '''save battery''' (CR2032 or soldered lithium cell), check for leaks.
* Replace leaking or dead batteries with a quality branded cell.

== 🔧 Preventive Maintenance ==
=== Capacitors ===
* Early SNES/SFC boards use '''through-hole electrolytic capacitors'''; later and Mini use SMD.
* Inspect for bulging, leaking, or crusty caps—especially near the power input and audio section.
* Replace aging capacitors with '''high-quality 105°C-rated''' parts, matching capacitance and voltage.

=== Cartridge Slot Care ===
* Avoid “blowing” into cartridges—moisture can corrode contacts.
* Clean cartridge PCBs with IPA and a soft eraser if needed.

=== Eject Mechanism (Original SNES) ===
* Lightly lubricate the eject lever’s pivot with plastic-safe grease if sticky.
* Do not force—replace broken springs or levers with reproduction parts.

== 🛡️ Storage & Handling ==
* Store SNES in a '''cool, dry place''' away from direct sunlight.
* Avoid stacking heavy items on the console—plastic can warp or crack.
* Keep cartridges and controllers disconnected when not in use.

== 📝 Periodic Checks ==
* Power on the SNES every 6–12 months to keep capacitors “formed.”
* Inspect the PCB for corrosion, leaking caps, or battery damage annually.
* Test video and audio output for distortion or color loss.

== 🛠️ Troubleshooting Basics ==
* '''No power''': Check PSU, power switch, and fuse (replace if blown).
* '''No video/audio''': Clean cartridge slot, check AV cable, inspect for cracked solder joints.
* '''Random freezes''': Suspect dirty cartridge slot, failing caps, or dry solder joints.
* '''Distorted colors''': Clean AV port, inspect for bad caps near video encoder.
