If you did not remove the batteries before cleaning the joystick, then there is a good chance that the liquid conducted electricity and fried the board.

You can find instructions to replace the board here.

The controller boards are about $15 on eBay.

thank you for your help


No problem! You can look for little black marks on the board. Sometimes it will char when it gets fried.

The impurities in any liquid excluding distilled water causes corrosion and provides circuit paths for the electricity which were not in the controller's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away.

Never use any liquid on electronics if there is power still connected to the device, even if it is switched off. In a lot of cases these days the power switch is not a power isolating switch so there's always some power on the board somewhere.

First do not try to charge or to turn on your controller and then remove the battery as soon as possible from the controller to minimize any further damage.

Then you need to dis-assemble the rest of the controller and gently clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) using a Q-Tip light moistened with the alcohol (not dripping) to remove all traces of corrosion and liquid. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives which may leave conductive residues and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that describes the process. Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields (if any) that may be covering some components as the liquid may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well

Hopefully after you have done all this the controller might possibly work correctly again.

If this process seems too daunting, take your controller to a reputable, professional electronics repair service, experienced in liquid damage repair and ask for a quote for a repair.
