Hi
This is a liquid damged board tiny bit around R9030 , P2V7NAND area. I replaced the R9030 as it was covered with dirt. PP2V7_NAND_VCC is 5v in C9022 and BURNT TP other side of the board near L9000.
U9000 PIN 15 EN signal PICCOLO_VEN1 Is missing.
IN Q9001 PIN 1,2 i get 8.7v. I get nothing from ll the other pins.

Any advice really appreciate .

Hi, this is solved. Found missing PICCOLO_IUVD. FOUND THERE IS NO PPBUS_G3H ON R9350 which create this rail. Bad trace on pin1 R9350. ran a wire from PPBUS and got ssd working.
It was difficult to access R9350 so i removed the cover shield. Thanks again for your help.
