Hardware Help me fix a random switch I bought on eBay?

[starfox51]

I bought a "not charging" switch on eBay. I figured I might be able to fix it. I thought wrong.

I took it apart. I plugged the Nintendo charger in and held the power button for 12 seconds.

I waited about a minute.

The copper heat pipe gets crazy hot. the fan is not turning on. No other signs of life.

Tried installing a known good battery. Same thing. Copper heat pipe gets hot. No fan spin. no other signs of life.

Should I see if Nintendo will take it in and fix it? I don't think I broke any warranty seals?

Thoughts?

that was your plan to fix it?

I was hoping that maybe the charge port was bad or the battery was bad. I have some decent soldering ability. But My skills with a multimeter are limited without schematics.

What if you remove the battery and charge it externally to the switch and put it back to see if it turns on??

I was thinking of doing the same but the busted ones are like $20-50 less than new here and buying outside of Canada is murder with exchange and fees.

Is there any visible damage to the main board? IE: A mod gone wrong?

Try sending a payload to it

 

[starfox51]

no signs of damage. Will try to get into rcm tomorrow. But I would think even if something like the nand was bad there would be the backlight on the screen.

what he is saying is it might be in RCM mode already which would not allow the system to charge

 

[DeoNaught]

auto rcm prolly, and some type of weird brickk

 

[starfox51]

Thanks for the idea of plugging in the wire. Look! bent pins on the top half of the usb C port.


This still doesn't explain why the switch doesn't boot when a charged battery is plugged in though.

Wondering if it's worth the repair.

bent pins on the top half of the usb C port.

Fucking don't plug anything else in, and replace that port, so many things could have shorted

 

[guily6669]

Or maybe you can try putting some epoxy glue underneath and press it hard with a tweezers, but best is really never use that port again...

 

[starfox51]

tried straightening with a bobby pin. No dice. I don't think this is worth ordering a replacement charge port since plugging in another charged battery doesn't let the thing boot. Let's see what I can get for it on ebay.

 

[guily6669]

and have you completely checked if its not shorting anything preventing the console from turning ON?

 

[DaveLister]

The IC for power managment can be replaced, some of the early bat issues have led to total failure of the Power managment IC - youtube videos knocking about on replacing them - third party docs around the time 5.1 OFW was released induced a spate of failed power managment IC's due to people not using proper cables or bad third party docks.

 

[MrWhosHacking]

did you test the fan... did you see if you cpu or chip need some compound on it thermal paste

i think so for the being it can short circuit things even fire maybe..

 

[borngborn]

My bet is on power management ic M92t36
They can be bought fairly cheap i hope u have good soldering skills

I agree with the above user...

BUT what if the console is actually bricked on purpose with auto-RCM installed?

you would need to send a payload 4 it to turn ON and the USB pins being broken doesn't help either...

Excessive heat most of the time means there's a short somewhere.

But considering you can't use a multimeter, can't give you any further advice.

The heating indicate short, this happend too on mobiles and tablets.

The first thing it's complete remove of this faulty connector, it can produce a short to motherboard, so you need to remove it yes or yes, you don't need buy a replace before seem the Switch living again.

Can't say to you that are the power management IC, some thing like a micro capacitor or another secondary IC can produce this too.

The first thing that I try after check if battery channels aren't shorted it's charge the battery directly for 3~5 mins with some adapter with same or more a bit voltage (like 0.5~0.8) than battery, then put back to Switch and try to power on.

If the Switch boot up, seems a fault related with the charging area only so you can skip another not related parts of motherboard and center only on charger circuit, if the Switch don't boot seems a general failure on the motherboard, so you should check all parts of the motherboard starting from the most hot part of the motherboard.

That one IC come hot dosn't mean that the IC are the problem, it can, but the problem can come from some input/outputs, you always should check the close parts to the IC before try to replace it.

Detect a short on microboards are harder, you should probe component by component and if you detect a short on someone you should desolder one of his contacts and probe again to discard a false positive, in resume you need a multimeter and you should have a lot of patience and work with a lot of care.

My last recomendation if you adverture to repair the motherboard, always use flux and protect the rest of the components with termal protect tape (or material with some properties) and use a low watt solder for microboards, try to don't damage any component and if you don't have experience with micro electronic components just let some expert fix it instead you.
