PS1 Analog turns off when rumble feature is used

[kjps86]

Hello,

I've got a PS1 which has an issue where the analog controls turn off as soon as the rumble feature in the controller is activated. The analog feature can be turned back on immediately, but dies away as soon as the rumble feature turns on again. The rumble does not work either, by the way--the analog turns off (light and all) and the controller does not vibrate at all.

Has anyone encountered this before? It is rather annoying and makes games unplayable with the analog sticks.

System information:
Original Playstation, NOT PSX
Tested with DualShock 1 and DualShock 2; I do not have a Dual Analog controller to try out.
Game tested: Spyro the Dragon 1

I am using a power cord that is not the original, but it seems to run everything else fine. I can test it with the power cord from a PS2 if needed.

Thanks for reading and for any suggestions!

Sounds like maybe a loose wire or a short in the controller, where the power to the rumble motors is tripping the analog selection button.

I just tested it with the power cord from the PS2, and then again with the cord I have for the PS1. Both times the system completely failed to pick up the controller at all now. The controllers work perfectly with my PS2, however. I'm going to start taking the system apart and see what I find.

So it turns out it was nothing more than a really loose (practically falling out) controller ribbon cable inside the machine. Problem solved!
