Macbook A1708 820-0040

Hello , Namaste.

There is a Macbook A1708 with a question mark sign. Tried Internet Recovery Too, the disk doesnt show under Disk Utility. Tried the Terminal Command "diskutil list" but still it doesnt show.

I have another dead model. Tried swapping the SSDs but still no luck ( I don't know whether that SSD is working).

Is there anywhere in the board that i can check ?

Everything in that area seems fine. I guess have to resolder the J8600.

I found the GTVR_ISUM_N line shirted to ground with resistance almost 0.
Is this normal?

Checked at Resistor R7431.

Thank You. Reflowing Components around the connector did it for me.
