Nintendo Switch right Joy Con not connecting in Dock Mode

Hello, I have an Nintendo Switch with the V1 Board Version. The Switch got an Water Damage. At the Moment both Joy Con,s wont work in docked Mode after that. Trying to clean all Water out of the Console.
Heared an electrizying sound out of the Console after sliding the Joy Cons in docked Mode inside the Switch. After 3 Times of trying it to work does the Switch shutting down with an error Code. Now the Console works normally. USB loading works normally and powering on too. Left Joy Con works in docked Mode now too. The right Joy Con works only wireless but not in docked mode. Right Joy Con works on another Switch normal especially in docked Mode. Can it be that the Joy Con Connector are now Corodded or an fuse/resistor anything else blowed on the Board Inside ?

I’m currently on vacation and don’t have any tools on site to take a look.

Has anyone had the same experience and had it repaired?

Hey,

Take things one step at a time. First check the joy con rail, unscrew it, then pop out the steel dowel pin with some tweezers, then you can remove the contact block and ribbon and inspect for corrosion, if any is present then give it a good clean and ensure no tarnishing. Afterwards, check the contacts on the ribbon itself for any breaks / damage etc use some contact cleaner after too. Chances are if there is corrosion then that may be your only problem.

Failing that then there is a few other things you can check board side but do the obvious stuff first :slight_smile:

Thanks, will give it a try tomorrow.

After cleaning everything and replacing the thermal paste, the right JoyCon only works semi-functionally. If a charger is connected, the Joycon is recognized at the connector. Sometimes without it but usually only with it. Which components on the board could be responsible for controlling the Joycons?

SMD soldering is no problem for me.

I’d probably first check you have continuity from the various areas of the board which relate, corrosion can eat away at traces, vias and resistors.

Here’s a continuity made semi complete for one side

and this is the otherside done by @jkyoho

In both cases are not a complete map but should give you a basic idea.

Provided continuity all good then you’d start looking at components which could cause the fault. Check these threads for related info.

Search the forum too, plenty more threads with this issue :+1:

Well thanks ! Searching for an Diagramm but dont find them.

Next Battery Change will test it in diode Mode !
