A1932 820-01521 - Liquid spilled, after cleaning 20V 0.53A but not turning on, T2 warming up

[it-solve]

Tried to push to DFU multiple times and not engaging. I can see how the current drops to 0 and back to 0,53 when doing DFu but won't be seen by other device ( via T3 cable which is tested and works. )

Melted connector on the audio board, but same with or without it.



Any suggestions?

Audio connector has T2 lines placed too close to PPBUS_G3H.
Check J6100 pins in diode mode; compare with good board.

All in 0.4-0.7 range apart than side grounds, matching a good board

If connector has been melt in such manner, something connected there is now damaged.

Do you get all AWAKE and SLPS2R voltages?
