Somehow, one of two plastic pins that come out of the top of NA connector (on the edges of it) broke, and I lost it.
Now it's not making proper connection with console, and by looking at yellow indication light inside of console (V5, V10), when moving the NA a little bit, light changes from bright yellow, dim yellow to no light, so I assume this pin is what prevents NA and port on console from proper connection.
I tried to glue something else instead of this plastic pin but it didn't help.
Any clues?
