لقد قفزت بعمق في استبدال المكونات دون تحديد عمليتك بوضوح لمعرفة ما إذا كانت هذه هي المشكلة.

في حين أن هذه الرقائق تشارك في الشحن في كثير من الأحيان أجد أن MOSFETs هي التي تتضرر وليست الرقائق. هل اختبرتهم؟

أعتقد أن أفضل رهان هنا هو مشاهدة مقاطع فيديو قناة Louis Rossmann على YouTube لمعرفة كيف يتتبع الخطأ.

You have jumped deep into replacing components without clearly identifying your process on figuring out if that was the problem.

While this chips are involved in the charging often times I find the MOSFETs are what gets damaged not the chips. Did you test them?

I think your best bet here is to watch Louis Rossmann’s YouTube channel vids to see how he traces out the fault.
