Nintendo switch oled dead help

Hi everyone
i am new to this forum , i do basic and a bit more then basic electronic i bought nintendo switch oled heg-cpu-01 dead no power , port look very clean , can confirmed nintendo never been opened i am the first person , no water damage
mint condition
done basic check around m92 around bq chip no short
amp meter when put on charge be out battery takes
15.28v 0.012a and goes up to 0.036a
with battery 15.28v 0.411a

i bought mechanic t824 type c tester
when i plug in i am getting pin 06,07, 18,19 OL
i done some research and find out one picture in reddit which show by the pins it goes to 6pin ic by the looks like that ic is VV market ,
can someone help me give some advice
now when i used mechanic again
only getting OL ON 6,19 pin but 7,18 pin now got 1.82 resistence if i am saying that correct i know that is wrong it should be by the good picture about 0.51
please accept my apologies just trying to figure it out what could be a fault

all help and advice appreciated it dint want try to unsolder things what is not related , also on termal camera nothing heating up

i know as a new user i cannot upload picture in
so
i am attaching a link for
pictures, i cannot include links too

Please check if the filter/choke (red marking) is fine and check in diode mode for readings at the violet marked test pads.

Hi Calvin thank you for answering
okey i put my multimeter on a diode mode
red prob on a ground and black on a tp point on a left side top
i am getting 0.782v
bottom tp i am getting 0.788v

right hand side top 2.167/2.2xx v jumping
right hand side bottom 2.712/3.xxx v jumping

when i touch from right to left too 1.4xx v
when i touch from right to left bottom 2.7xx v

is this any good for you

or i done wrong sorry

The readings ~788 mV are fine.
At the filter it is only necessary to test if there is continuity from left to the right at both lines. The both pads on the right side should show the same ~788 mV like the test pads.

i done beep beep mode on multimeter and there is no beep
i tested on next 1b w10 ic it got same ic and in beep beep mode it beeps
so does it mean in my case my ic is faulty yes ?

i dont have donor board i have macbook boards iphone boards maybe i can pinch from there ?

i find on macbook air m1 same component do you think it should work can i try it ?

If the filter/choke has a missing continuity and one of the right pads reads has oL in diode mode I think you found the cause of the issue

On a macbook should be also filters for the signals but I don’t know where exactly. From my knowledge there are single ics and not the double ones like on the Nintendo.

Calvin you a legend mate i remove from macbook air m1 the filter next to cd32 ic i remove faulty from nintendo switch filter replaced now
i checked with mechanic type c reader and i confirm i believe we in a business mate adding a picture
still need to add and test in a frame but i believe we looking positive

i got excited to quick now wanna cry :sob:
was busy at work plus crazy rule you got limit number if comments to write and you need to wait fir 22h

put motherboard in a housing plug the power cable with an amp meter 15.20v 0.430a
and no life double checked with mechanic all green everything okey

pull out motherboard start beeping with multimeter m92 clean everything
bq okey
but at max 77812 at the edge right hand side where is 2 big coils 2x big and 2x small caps beeps 018.2 oms and another side 000.6 oms
gnd side

so it is mean i got short
i need new max chip ?
i tried to look info but its confusing by the looks like it is unknow fault

anyone can advice please is this board goes to a junk ?

then i looked on side a
again next to max 77620

Hello, if you didn’t solve it yet. it’s ok if caps around 77812 beeps, due to low resistance, so it’s not the problem for sure, unless they don’t show exact 0.000ohms
Try power it from bench power to see how much A you will get, but first make sure to test it from vsys point to ensure you have no shorts.
