Dreamcast Controller Port 1 not working , how to fix ?

Post by **s8n** » Mon Jun 09, 2008 11:41 pm

hi team , i bought some stuff from a guy recently and he said there will be a delay " i will post something small as a bonus" , well i got it today amongst all the other gear it was right down the bottom of the box. When i saw it i was floored , he sent me a bonus untested Dreamcast.

I have done a little testing and found that Controller Port 1 is not working at all. Im still stoked with it but if i can fix it , it will be icing on the cake.

any info is sensational

it's something about a fuse on the resistor or something, this breaks when 3rd party pads want too much power, i think.

Vlame hit the nail on the head. Just google F1 resistor dreamcast. You sould find anything you need to fix the problem.

Sometimes the controller sub-board can go bad. I know some places on-line may still sell replacement controller boards (the board with the 4 controller ports on it). Also, some controllers can cause shorts. I have a controller which doesn't work with ports 1 or 3, but it does with 2 or 4. All my other controllers are fine. This one controller also can't have a memory card in it or it screws up lots of things.

more great info thanx marurun , i have a few backup Controller Ports and have installed 2 to no avail. Dismantling the DC before i found the Ribbon Cable is corroded i think the Ribbon Cable connector is corroded aswell hampering a proper connection to the Motherboard or done worse to the M/B possibly a short.. I even tried a new Controller Board Ribbon Cable and another Controller Port still same result.

im thinking my last option is a total M/B replacement

i have done some more investigating and found that the Controller Ribbon connector on the M/B is corroded , if i were to get it working from its current state it could corrode again and damage more parts. I think the best option is a Replacement M/B.

If you can clean up some of that corrosion you might be OK. It's worth a try. Take a pencil eraser to the board and see if clean-up returns it to functionality, and if it does, keep using it until it's toast :)
