Playstation 1 (PS1) System works, but controller ports don't. HELP!

--

 

From the description, no. The controller port module is the same on all the grey PlayStation models, but on the little white PS1 they are soldered directly to the main circuit board.

Having said that, the controller ports are most likely perfectly OK, and the problem is being caused by a blown on-board fuse. There are a number of SMT fuses on the main logic board - they look like little black plastic blocks, but are marked "PS6xx" on the silk screen. The problem is most likely the one marked "PS605", which is a 600mA fuse that supplies the 3.3V to the controller ports - there is an additional 800mA fuse marked "PS602" that carries the 8V to the controller ports, but with real DualShock controllers this just runs the motors and everything else runs of 3.3V.

And you can still get mod chips - there are several people selling them in the marketplace. Which supplier is best depends largely on where you are.

 

You could always move the modchip into the other system as well in the meantime. That is, depending on the chip in the original system (I could determine which chip by the wiring). What country do you live in takensorryuser?

@TriMesh
What kind of things under normal use would cause a controller port to blow?

 

The 3.3V fuse is normally damaged wiring in the controller. The 8V fuse can also be blown by a worn-out motor in a DualShock controller or by certain badly designed unlicensed 3rd party controllers.

@takensorryuser
I can send you an MM3 chip for free, PM me your address and I'll send it tonight.

@TriMesh
Thanks for the reply.
