First steps to take:
NES Repair:

1. Clean games
   1. Disassemble cartridge (might need special tools, check amazon or ebay)
   2. Gently use rubber eraser with no grit on edge pins
   3. Use window cleaner or isopropyl alcohol with lint free cloth
   4. Spray contact cleaner on the pins
   5. NEVER EVER BLOW IN IT
2. Clean NES connector
   1. Ancient cleaning kit
   2. Spray contact cleaner on the pins
   3. Boil it
   4. Bend pins (risky)
   5. Replace the connector
3. Already tried all steps for cleaning game & cleaning NES above?
   1. 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
   2. Try another game cartridge
   3. Try another NES
   4. Try r/consolerepair

Power Supply:

1. 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.
2. 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:

1. Take them apart and clean the contacts on the PCB, not the rubber membrane

Display problems:

1. Use a CRT monitor or TV
2. Don't use an LCD or LED TV
3. Use the composite RCA/AV connectors on the side, don't use the RF/antenna/aerial
4. If you must use RF, don't use the RF/antenna/aerial switch box, use a small adapter instead
