I need this system repaired and serviced.

Hi,

ifixit does not do repairs.

The people who voluntarily answer questions on the forum (and anyone can answer) provide advice on how to fix it yourself (i-fix-it) or if you can’t what the next best option may be.

Here’s a link to the ifixit Nintendo Entertainment System Repair guide which may be of some help in opening the console to inspect the components for any obvious physical damage, including corrosion etc. If there is corrosion or water damage this link may be of some help Electronics Water Damage

Cables etc are available on such places as Ebay etc. Just search for cables and adapters for Nintendo NES to get results for suppliers.

Once you have inspected the console and have the cables and start testing it, if you have more problems come back to ifixit to get more help if you need to.

You could also scroll through the ifixit list of professional repair services for ones in your area that may be able to repair it if you can’t do it yourself
