Hardware Nintendo switch lite bq24193, USB port overheat

[cdfertolo]

Hi, I'm new here I'm from Italy. I'm sorry for my bad English.
I bought a faulty Nintendo Switch lite from EBay. It doesn't power on and It doesn't charge. Nothing on the screen.

After inspect the motherboard, I found
a little capacitor with a solder bridge with another cap, right above the mt92. I already fix it.

I measure the voltage at the battery: 2.72 Volt.

I check for short along the board and I only found a very low resistance on both sides (3 ohm and 0 ohm) on a capacitor near bq24193 chip.

I tried to charge it with four different phone charger and the official charger.

With two of them and with the official charger the motherboard draws 5.22 volt and 0.00 amp.

With the other two, it draws 4.92 Volt and 1.45 Amp, and suddenly the bq24193 chip became really hot. Also the USB port and the metal shield above it became hot but they’re colder than the bq24193 chip.

Does anybody have any advice on what I can check or do to try fix it?



Thank you very much!

I don't know if you replaced the bq24193 chip.
If the bq24193 chip gets hot, that usually means that there is still a short.
Also the fact that the original charger does gives you 0 amps indicates it has shut itself off because it thinks that something went wrong.

There are a lot of videos on Youtube where people much more skilled than me give a lot of advice about how to repair this and which capacitors to check:

Hi, thank you for your reply.
Unfortunately I found four missing pads under bq24193 chip.

The lifted pad are 15, 16, 22, 21.
Anyone have the diagram of it?
Or is this unfixable?
Thank you!
