Nintendo NES Complete Restoration Part One: Disassembly Video


What is a complete restoration?


Many times when buying used Nintendo NES consoles from eBay they will need quite a bit of work. When I say a complete restoration I mean taking an old dirty non-functioning console and making it as near to the original condition as possible. Not all defects of course can be corrected but this series will show you how to disassemble, clean (inside and out), replace the 72 pin connector and diagnose and repair the control pads on an old NES console. I don't recommend trying to restore systems that have yellowed, cracked or are missing the front panel. Even if fixed as much as possible these systems aren't really desired by buyers and it would be a waste of valuable time to try to restore them.
