I replaced U9300 now PP1V2_SSD_HOT short is gone but only ssd voltages I get is
pp3v3_s5_ssd 3.3v.
STORAGE_LB_EN: 3.3V
SSD_RESET_LB_L: 3.3V
LPSR_EN_LB_L: 3.3V
SSD_BOOT_LB_L: 1.7V
"C9405 PP3V3_2V7_NAND_VCC = 2.7V
-----------------------------
R9420 P2V7NAND_EN = 0V"
This is strange, don't you think?
Enable signal is required first; and should be present, if you get 2V7 output voltage.
Sorry that was a typo. Is there anything else I can check?. Is it possible to replace the nand ?. I dont have donor for this board, possible to buy new nand?. also which ic number do you suspect?.
