PS5 edm-031 soutbridge resistor

[vektro3]

Does someone have an edm-031 board and can give me a reading from a resistor (yellow marking)
and resistance to ground at the 3.3v line (orange marking)?

hello could you tell what is the resistance to ground on these two "red" coils??? I have a dead edm-030 board with 61gg sb. These two coils are shorted, is it correct?, I think sb is dead.... I have only 12v on board, I replaced 3219a and da9065 too... no changes.... I didn't find any else part shorted on board.....except these two coils

update: I found out that these lines are 3V.... so I removed SB and all connected caps I found, short remains..... I injected voltage nothing gets hot...... I have no idea where else this line is connected..... any ideas-help???? thanks

The little 0-Ohm resistor should read ground if a 61gg southbridge is on the board.
The both bigger components are emi ferrit beads 0603 and feed by the line 3.3V_SS_PG2_CLK.
This line shouldn't be shorted and is generated by the SB pmic DA9065/RT5126 on pin 7.

But to begin with, I would start a bit upstream and check if the 5V is shorted and if so, remove fuse F7003 and check if 5V are back again.
