Hello,

A1708 820-00840-A device had liquid damage.
C3405, C3400, C3306 I disassembled them. The device is turning on and charging. However, when I open YouTube or visual sites, it freezes, the screen turns black or crashes. Is this problem related to U3100/3200? Where should I look?

I transferred the motherboard to another working device and the problem continued.
They changed the battery on the device because of this problem, but I guess there was liquid damage on the device and they did not notice it.

I tried with another ssd, do I need to try again? As I said, there was liquid damage and the 3 parts I wrote about in the type-c area were rotten.

Do I need to try again via USB?

No need, if already tried another SSD with new macOS installation.

If is no software issue, I suspect CPU then; probably iGPU related.
You can try to heat using quality flux, to burn eventually accumulated crap underneath.

The CPU area is very clean, there is no liquid damage in the CPU area, are you sure?

C3405, C3400, C3306 were rotten, I took them apart and haven't put them back yet.

If there is something under U3100/3200, will there be such a problem?
