Master System left doesn't work

[peachey777]

Hey everyone. I have an issue with my Sega Master System where left on the d-pad does nothing. I have 2 controllers and I've tested both on my Genesis and they work just fine. All the pins on the controller port look fine and using a multimeter I've tested the pins connection to the board and that seems fine as well. Beyond that I have no idea what the issue could be. Any ideas?

Thanks

have you taken it apart and cleaned the contacts?

sounds like the pin isn't making contact, something like this happened to me with a genny 2, open it up and see if the pin is pushed in on the connector port of the system. get a flat screw driver and try to even out the pins by pushing the metal pin flush with the other 8.

pin 3 is your problem.

I have cleaned the contacts. It's good to know what pin is used for left, ill open it up soon and take a look.

I've opened it up again to take a look. Everything looks fine to me.

Unless is it just a funny different reflection, those pins on the righ tport in your picture look a little thinner than the others. Maybe try very carefully bending them all ever so slightly all one direction a little bit in case one or more of them are managing to float in the plug without making a good connection?

from this pic flip over the board and flatten the pins in uniform.

Sounds weird - but try turning on the system without a controller in the port and plug one in when it has already booted up.

I have one SMS console where the controllers will only work properly if the controllers are inserted after the system has booted - don't know why yet as I haven't had time to diagnose the issue.

Out of curiosity, what controller is being used and for what game(s).

Why I ask:
I think certain games, like Bomber Raid for example, doesn't work with Genesis controllers. I think it even behaves like you described (no left control).

[peachey777]

I tried bending the pins a little, moving the controller around in the port, I also tried Lost Monkey's suggestion. None of it seems to be working. I might try and find someone who could re-solder that pin to see if it helps. Otherwise I might just get another master system.

@nightrnr: The only game I own for it is Hang-On. I've tried using 2 different Master System controllers and a few Genesis controllers.
