Lenovo Yoga YT3-X50F Tablet: Charging Socket Replacement Issue, Smoke & Short-Circuit

Hello,

I wanted to replace the charging socket in the tablet as above. I guess the tablet charging worked before trying to replace it (only the socket was a bit broken). After purchasing the part, it is - a USB board with vol + / vol- buttons on the flex and connected to the tablet, smoke flew out, probably from the connector (photo 3). Then, when I disconnected them from the board, it was short-circuited and it was warm after connecting the power supply. It seems to me that the plug was poorly made and it had a short circuit (I attach a photo). I was looking at connector no.3 under a microscope and there is nothing wrong with it (I attach a photo). I got the second plate, everything looks nice, because the charging LEDs are on and even the tablet shows charging so much that it is not charging. As I measured the voltage at points 1.2, it does not increase after connecting the charger. Maybe a fuse has flown or something, maybe I will fail, someone will find someone willing to fix it?

Colleagues suggest something ?? ?

In the middle photo you have a big babola, there is a short circuit on pins 2-3.

Yes, this is babol (listed), this is the plug I wrote about, now it's OK. Which does not change the fact that it does not land.

I think I found the source of the problem now, how to fix / replace it ... is anyone willing? of course for money. Set of elements marked with number 4.

If you want to outsource it to someone, create an appropriate topic in the Bazaar section.

And how to fix it do you know?

You have to re-solder the damaged coil, and it's hard to say if anything else.

Return the system to the site about PLN 50 plus labor, if something more has not been awarded.

PS:
... there in the photo, if I'm not mistaken, you can see a coil with a ferrite core, and next to it there are particles as if a crushed varnish from a winding wire may burn this coil. Just out of curiosity, take a picture only from the side of this coil, not from above.

I will do tomorrow, thanks!

99.9% that the chip next to the coil also went.

Witam,

poszukuje

charger 3585-2166 do tej płyty, może koledzy mi coś podpowiedzą.
Lub sposobu żeby go ominąć.

Colleague the component is an ic 358s 2166, it can be replaced by the 358s that is in the samsung tab t210 t211, I also found it in samsung mega 5.8 i9150 but I'm wrong the model, what I can't find is the schematic of this lenovo

Dear members! Can anyone help me to identify the part marked with amber circle. It seems that in our case that (diode?) is burnt, so we are unable to identify any part number etc.

Can anyone support?

Thanks!
