Board is 820-3476
R6101 and R6103 resistors connected to PP3V3_SUS are getting dragged down somehow. I cannot figure out why. When they er mounted to the board they measure R6101: 0,8K instead of 3,3K and R6103: 1K instead of 100K. When I pull them readings are correct according to schematics. When I put them back (or mount new ones which measure fine until they are mounted) they read too low again.
Diode mode reads 0,370 on PP3V3_SUS. A little too low voltage drop but cannot find the culprit.
I injected 3V into PP3V3_SUS and C1204 getting hot. I removed it and nothing else gets hot. But still resistors near U6100 reads incorrectly.
Any idea to what is going on and what's my next step?
Thanks
