hi, on my previous post I had asked about a no backlight issue on the same 820-3115 board. well before i could figure what the issue was the board decided to randomly blow a capacitor taking the u9410 3.3v/HV POWER MUX CHIP along with it so i replaced the blown capacitor along with the u9410 chip. Now i only get a green light all power rails except S0 are enabled. after doing a lot of troubleshooting i believe the issue lies in between the PM_SLP_S4_L and PM_SLP_S3_L which may be causing no 1v5CPU_EN which is not letting the 1.5v S3/S0 FET to enable.
So ive come to ask for some help and guidance. Thanks.
