MacBook A2251
Brought in because the customer was not getting image for their machine anymore. Could hear sounds but no video. Another tech in my shop attempted a screen replacement. After the replacement the device no longer gives any power up sound or display still.

Current State:
Just the motherboard on the bench, the machine will boost to 20V @ 0.12-0.23amp draw before dropping down to 0.045a and staying there.
With the battery plugged in the machine boosts to 20V @ 0.9-1.5amp draw.

PPBUS_G3H - 12.62V
PP3V3_G3H - 3.366V
PP5V_G3S - 5.141V
PP3V3_G3S - 3.344V
PP3V3_S5 - 3.366V
PP2V5_NAND_SSD0 - 2.519V

Attempted to connect to AC2 but the machine does not appear in DFU.

Here is the T2 under thermal imaging as it's plugged in. Draws 0.12-0.23 amps then drops to 0.040a

Try to force it into DFU with external switch method.

Attempted external switch with no change. After powering off the machine with PMU_ONOFF_L amperage drops to 0. Then pressing the DFU button for 3-5 seconds does nothing. I did measure to make the sure button press is connecting the 2 points and continuity shows it is.
0V on DFU_STATUS.
