스마트 패드 전원부 부품이 탄것 같은데요, 이거 점검이나 교체하는 업체가 있을까요 ?


Chuwi Hi10 이라는 모델이고 고가의 모델은 아닙니다.


혹시나 고칠 수 있을지 여쭙습니다.





노랑색 부분이구요, 아래 사진에서 확대해 봤습니다.









다리 5개면 전원부 관련 칩 아닐까요 ? 흑흑...



우측 상단에 있는 또다른 다리 5개 칩이랑 같은걸까요 ??

Hi guys,

thanks again for the help. After I finally found an
R1112N431A and
built a small circuit with a MOSFET to invert the enable input, I had to
realize that unfortunately nothing was happening with the tablet.

I then searched again and came to the conclusion that it
is probably not an R1112N431A, but an
ETA1036-50S2F-T, a step-up converter, which also has the marking code CP
..

Unfortunately, the wrong component seems to have broken even more, because
unfortunately nothing
happens even after soldering in the ETA1036-50S2F-T . It is also present at its enable input 0V and at
Output then also 0V. The voltage from the LiPo battery
i.e. approx. 3.8V.
Even if I manually set the Enable input to the Lipo voltage,
there is 5V at the output, but the tablet cannot be
switched on.
