Hardware Replaced left rail, joycons doesn’t get detected(but charging)

[Akira]

I recently replaced my switch’s left joycon rail since the original one was very tight to the point that getting in/out the joycon will make you think that the joycon might be damaged overtime.

I replaced it with a new part, with all the disassembly stuff ofcourse. Now the left joycon slides in without any trouble, but the thing is switch doesn’t detect it as docked. It does charge the joycon, but having this problem, I can’t play on handheld mode now because when i open any game, it asks me to either dock both joycons or play tabletop.

I tried all those fix i found by googling it, unsyncing it, then docking it again, disconnecting the controllers then restarting etc etc to no avail.

Hope someone can help me.

Did you unplugged a buttery before changing it? Try to clean ribbon cable with IPA make sure you din't have any debris stuck in it.

I did unplug the battery. Don’t know what IPA is though.

I just got NS with same problem, ill let you know if ill be able to successfully repair it. IPA - Isopropyl alcohol

Spent all night testing my one, looks like there is several traces in to the internal layers of PCB got blown... mb because it was not handled well in to the disassembly process...
Problem with my switch looks like it's a brand new one and i can't pass joy con connection screen for initial setup...

Oh man, now i am starting to feel that mine is the same. I guess i’ll never be able to play handheld mode for a while

If your left joy con was working before you swapped the rails, then it sounds like you didn't put it back properly?

As a test, put the old rails back and see if it works? If it does, good, now put back the new rails, if it still doesn't work, then maybe the replacement rails is faulty.

I did that, now even the OG rails is acting the same way

Mmm, only thing I can suggest if you have access to a LEFT joy con from someone to test?

I had issues with my LEFT joy con, only charges but wouldn't connect, but I didn't replace the rails as I didn't have access to one at the time and I would have had to order it.

I went into my local games store where they were selling second hand joycons and asked if I can test one out, and it worked straight away, so my joy con was the issue, ended up buying the second hand joycon. I didn't have any friends that had switches so couldn't test.

I have tried it with a workin left joycon, same problem. I’m guessing i screw up the disassembly somehow. Sad

Sorry, just re reading your original post again, so you changed the rail on the SWITCH not the JoyCon correct?

If so, I got my replies mixed up then, so you must have damaged something during the rails swap over.

Yup the metal rails

Did either of you manage to fix this? it's the right joycon not being detected in my case, it doesn't charge either. New rail, new connector lots of IPA but nothing. It had some minor water damage, it's stuck on the attach joycon screen so cannot test further.

Same here as original poster

Sorry to say, your joycon is stuffed, my old joycons, I did the same, still no good. I went to my local games store where they had pre owned joy cons and asked if I can test one to rule out if it's the Switch or the Joycons, and in my case, it was the joycons. Yes they are expensive piece of controllers.

If you can something like this in your area or know someone with joycons so you can test.

The joycon is fine, I've tried two known working ones. It's a switch motherboard issue.

Well it would have been NICE to include this info in your original reply so people know where your at, instead of assuming.

If it's a motherboard issue then that is out of my scope to assist you, it could be that your minor water damaged joycons shorted something on your switch.

Good luck, and worst case scenario, find yourself another hackable Switch.
