820-00239 Macbook Pro SSD not detected

I have a Macbook pro 2017 (820-00239) that dosent detect the SSD.

It's no water damage, just stopped working. Read the lines between C9402, R9350 and C9401 are weak spots so I did jumpers, just to make sure. No difference. Have checked for short on sourrounding components but not find anything.

Any ideas how I can continue? Thanks

Yes, you are right. it's 4924!

1 Both sides of DCIN fuse F7005 Is same value. ~0.47V (going up and down sometimes between 0.6v - 0.4v

2. Pin 1 (and 2) on R7020 = Close to 0V ~0.0x...V

3.Same as F7005 on TP_DCIN_ISOL_GATE between 0.6v-0.4v...

Hi,

I have a A1502 that works fine on battery (since its have some juice left) but does not charge and have no light on charger.

A1502 Early 2015
Motherboard 820-4924

What I Have checked so far:
Reset SMC
No physical damage on board
Exhange the charging port
3 different chargers
PP3V42_G3H = 3.42V
PPBUSS_G3H = 11.38V
PPDCIN=0.58V

Any idea how I can continue? I have some motherboards for spares, but not exactly same model.
