Troubleshooting

Start from the symptom, not the screwdriver. These pages walk through the likely causes in order — cheapest and most common first — so you know what’s wrong before you open anything.

Planned pages

• Won’t power on — batteries, fuses, power switches, regulators
• Powers on, no picture — screen vs. cable vs. board, in that order
• No sound / crackling sound — speakers, headphone jacks, amps
• Cartridge games won’t load — contacts, slots, and when it’s not the cartridge
• Controller acting on its own — drift, ghost inputs, and connection drops

All coming soon. Stuck right now? Describe the symptom in a repair request and we’ll diagnose it at the bench.
