psx ports
 

hi my psx has lost the use of the game pad ports
the system boots 100% but no controlers
any one know what fuse? chip?that is gone

thanks

Easy fix if you are good with a multi-tester and solder iron. Mirco fuses are the little black surface mount things, usually with a 15 or 30 printed on them, 2 contact pads on either end. The smaller black things (or blue) are resistors and the yellow ones are capacitors. black things with a mark on one edge are diodes, the 3 pad ones are 2 way diodes.

The fuse you are looking for has a 30 on it and is near where the power connector goes. Test all of them anyway, should be 0 ohms, if any are opened replace OR if you dare, you can desolder it and short the 2 pads with a drop of solder. If you are using a cheap controller, you can modify it to use less power with a
500-1000 ohm resistor on the power line. If your cables are chewed up from a dog or something, replace them! Especially if you just short out the bad fuse, you’ll want to know what blew it in the first place to avoid any further damage.

thanks
