Problem with my Genesis 6-button

Post by TheSegaSaturnGuy »

Okay so I have a genuine Sega Genesis 6-button controller and it has a problem. The controller is constantly registering a left d-pad press. I took the controller apart and stripped it down to nothing but the board thinking that maybe something was jammed but there is nothing. Even with nothing touching it it still is constantly registering a continuous left d-pad press. Is there anything I can do that might fix this? I did a google search but came up empty, any help would be greatly appreciated!
I am buying all Saturn games, PM me with your offerings and I will let you know if I need the game or not! (Everything must be CIB)

Currently trying to knock off all the sports games, would like to get them <$5 each! Of course if you would like to donate them I will gladly pay the shipping! :)

If there's nothing jammed in the controller, I suggest that the next step you take is to check for corrosion or a crossed line. A good starting point for this may be to follow the path coming off of the left node all the way to the integrated circuit. Check along the way for corrosion or anything that may be crossing over the lines.
Here's what a standard MK-1653 looks like. Please note that not all sega controllers are identical on the inside, but they operate by the same functions.

It might do you some good to scan the circuit board and post it here allowing some of the experts to contribute their thoughts.

As a final thought, I'll say that I've seen a simple spray can of electrical contact cleaner work minor miracles.

I'm not an expert, so take anything I say with a grain of salt.
