    820-02652-A, M2 MAX, after fireshow:)

    First of all, welcome to the forum! "now starting and booting" So board is detected into DFU and probably pass Revive. An authorized Apple service can recover the data in DFU mode. Don't you have a friend with such kind of authorization?

    820-00165 need advice on this repair(jumper needed)

    Use tiny enameled copper wire. I prefer 0.03mm for such king of job. Once done, fix the wires with UV curing glue.

    A1990 820-01827 Liquid damage on U9580 SSD Buck. Likely Braindead?

    Which schematic used, 01041, or 01814? Really strange no short on L9580, if there was liquid around U9580. Is now the machine recognized into DFU?

    A2251 - 820-01949 - liquid damage, powers on, only external display, solid apple logo

    Check U4802 signals with board alone on the desk. Nothing else can affect lid sensors; as they are placed on the MLB.

    A2337 820-02016 5V 450mAh Liquid Damage

    "Does 12.3V from ISL mean that the CD32 charging circuit is operational?" No. U5200 can generate this voltage with just 5V input; before CD3217 chip switches to 20V. If you resolder F5200, PPBUS_AON still not present? Be sure the fuse is good.

    You can try, but I can't assure you 100%.

    820-02020 20v but no boot

    Press power switch 5-8s, until lock symbol disappears. Then try to put the machine into DFU.

    A2337 820-02016 5V 450mAh Liquid Damage

    Something like 3V8_AON, 3V3_S2, 5V_S2, etc. All MASTER/SLAVE PMU BUCKS to check also.

    A2251 - 820-01949 - liquid damage, powers on, only external display, solid apple logo

    Any liquid sign on J8500? Check diode mode to ground on its EDP_INT lines. What about U4802 signals (with lid open)?

    820-01949 touch bar and lid close problem

    "hall sensor not working at all" What kind of measurements have you done? Can you post U4802 signals (with lid open)?

    Macbook A2337 Right Speaker Not Working

    I still think that you need to play more with external switches; for both DFU and ONOFF pads.

    A2337 820-02016 5V 450mAh Liquid Damage

    Yeah, Main Logic Board. So you have a problem outside of charger circuit. Check diode mode to ground on all secondary power rails.

    Other JT400's voltages and signals OK?

    820-01958 20V 0.1A

    You should try to enter DFU using external switch method.
