Rumble not working

Post by Killer_Code » October 24th, 2015, 5:30 pm

Hello guys! I have a little problem with my psx. My cousin found a memory card that didn't have a plasic on it and he put it into the memorycard slot and now, if i plug any dualshock controller into any of the ports the controller doesn't rumble when it should. Is there anyting that i can do in this situation?
It's not the amount of the ram. It's how you use it.

Looks like he somehow blew the DUAL SHOCK load fuse. Odd. What model is your PSX?

It's an scph-7502. It seems a little odd to me. I have no idea why the Controller port suffered damage. :shrug

Yeah. Check FB122, FB121, FB120, FB119, FB118, FB117 and FB123. Especially check (the inductors) L104 and L106.
There are a few diodes around CN102 too, so check them also.

I assume from your wording that the PSX powers on okay, so it could very well be the controller. Try another.

Check if the 7.5V supply pin is still outputting 7.5V,

sounds as if the memory card did short-cut pin 3 and 4 (7.5V and GND), thus blowing some fuse or inductor.
Should be pretty simple to find the broken component by tracing the 7.5V line with a multimeter.
