Nintendo acting weird when inserting controller.
I have a weird problem with a NES i bought some days ago.
The console is working, as in it starts and the game runs.
The problem i have is when inserting the controller.
I know my controllers work because i have tested both of them on my friends system and they work perfectly fine.
So when i insert the controllers to my system, as the game is running, inserting the controller into the port the games registers a "start"input and the my system stops registering any controller input at all. The controller cant communicate with the system being inserted.
So what have i don't to try to fix this. well we transferred my controller ports to my friends system and they work perfectly fine in his system.
so that made me think it was maybe a 72 pin connector problem. That is my game isn't having the right connection between the game and motherboard.
so we swapped the connector. NOPE, that didn't work either. So whats left them, well the motherboard.
I searched the whole mother board after soldering bridges and cleaned it all out the electronic cleaning solution. Still not working...
Anyone know what the cause is?
