In this video was meant to be a repairing a Nintendo Entertainment system that came out in 1986 and costing around £150

I got it from ebay as spares or repair the problem it had was a red flashing light

Thing to try
1) Clean the games

2)Try a difference game

3)Put the game in the console and move the games around you might clean it and get a connection

4) Put the game in the console but don't push the game down

5) Take the console and clean where the game goes and the board

6) It might be a chip on the board 3195A

7) BUT in my case in was only flashing a red light with out a game in there so make sure you put a game in it test out

And I will clean the board with alcohol 99.9% and clean the shell in warm soapy water the putting it in hydrogen peroxide 12% using stainless steel bolts to hold the shell down and only had it in there for one day as it was not that bad

Tools used
Screw driver set
Alcohol 99.9%
