    820-0045 kernel panic

    The board is experiencing frequent kernel panics during boot and occasionally also during normal operation (once it managed to boot successfully). We are suspecting the problem to be CPU or SMC related. There are no signs of water damage.

    A1708 no backlight

    The display has no backlight anymore, board is working and has backlight with another display, are the displays repairable? is there any fuse on the display controller board?

    820-3476 Bootloop (but sometimes turns on)

    It had Liquid damage all over it. The Fan spins for 1 sec and stops. Then it starts again, to do the same thing over and over again. Sometimes (Especially if we start it for the first time after a long time) it boots, no problem whatsoever. We already replaced EFI chip after ultrasonicing it...

    820-00875 PPDCIN_G3H at 5v

    I just noticed, that PP3V3_UPC_XB_LDO (measured near U2890) is constant 3.3V with the USB-C connected to the first connector. However if i connect it to the second one, PP3V3_UPC_XB_LDO Spikes to 3.3V and drops gradually untill it hits zero. Then it gets another Spike and repeats that over and over.

    Corrosion was on U2890, U8400, Q8401 and in that area (Possibly under U2800 too). And very little corrosion around U3100. I get 5.2 Volts on PPDCIN_G3H_CHGR and 0V at PPBUS_G3H It doesnt have a short at PPBUS_G3H. It probabbly is U3100 or U3200 right ?
