First steps to take:
NES Repair:
- Clean games Disassemble cartridge (might need special tools, check amazon or ebay)
- Gently use rubber eraser with no grit on edge pins
- Use window cleaner or isopropyl alcohol with lint free cloth
- Spray contact cleaner on the pins
- NEVER EVER BLOW IN IT
- Ancient cleaning kit
- Spray contact cleaner on the pins
- Boil it
- Bend pins (risky)
- Replace the connector
- Try a Game Genie, the thicker PCB might make better contact with the NES and the tighter connector might make better contact with the cartridge
- Try another game cartridge
- Try another NES
- Try r/consolerepair
- NES Schematics
Power Supply:
- For the NES any power supply that can provide 850mA (or higher) at 9V and has the right shape connector will work. The original NES uses an AC adapter but a DC adapter will work too.
- For the Famicom you must use a DC power supply with center negative that can provide 850mA (or higher) at 9V-10V. Do not use a NES AC power supply on a Famicom!
Controllers:
- Take them apart and clean the contacts on the PCB, not the rubber membrane
Display problems:
- Use a CRT monitor or TV
- Don't use an LCD or LED TV
- If you must use an LCD or LED TV, get an upscaler
- Use the composite RCA/AV connectors on the side, don't use the RF/antenna/aerial
- If you must use RF, don't use the RF/antenna/aerial switch box, use a small adapter instead
