5v boost ic chip

Hello, can you help with my problem? After installing the SX Lite modchip in the Switch Oled, the fan stopped working, the joycons do not charge. The voltage at the fan connector is 0v, but there is no short circuit to the ground. Switch, works fine, the joycons are detected and work in flight mode without Bluetooth, but charging is not going on. Switch V1-V2 had a pu 5v chip that was responsible for charging the joysticks and powering the fan, but I can’t find it on oled.

Good day mates, i have problem also with alj ic, i accidentally damage it, can anybody tell me what it controls, eg. Brightness, fan or joy con charge… etc
My board is a v2 mariko switch, i am reffering to the alj chip on top not the middle one, thanks for the one who will answer question

hi, i got the same problem, you could check the IC MAX8969, in my case i follow the instructions in the forum http GBAtemp with the title: Switch OLED. The fan is not working and joycons are not charging
