    MBP A2338 - board 820-02020 No image int.

    Hi' everybody. I have a M1 MBP from 2020 with a liquid damage. CL053 PP3V3_S2_WLBT_ISNS was shorted, replaced and now the MBP is running. I get image on external screen but not on internal. I have tested on other known good display without any image. Testet in known good housing as well - no...

    820-02020 M1 A2338 Power cycling

    Hi’ i’ve had a similar issue with cycling amperage. I have found it only by thermalcam. There was no signs at all and because of that my thermalcamera helped me a lot:-). My PP3v3_S2-WLBT_ISNS was short on CL053 (underfilled area). ISO did not do it because the temp on damage was low (cycling)...

    Thank you again. If I find a solution I will let you know. It could be a dead one this time. Is it possible to restore T2 if the CPU is dead?

    Maybe it is a “dead fish” or dead Apple😅. I have restored it with success but still no image on internal and external display. No light in CAPS-log but trackpad still clickin’ boots to 0.350 amp and returns fast to .153 amps and stay here. Cpu low temp rise. Thank you for your help

    U7710 is wrong on earlier mentioned… pin 13/14 get 5.06 voltage. Sorry for that!

    I understand your question about changing a chip without EN voltage. I lost my mind. I do not get why U7711 () and U7712 have a EN of 3.29 but why do they not work as U8112/11. They 8112/8111 have voltage on pin 5/6/4/3 as well…. U7711/12 does not L8100 1.18 volt L8100 diode 258 L7702 diode 033

    I have messured. I hope you will be able to understand my results: U8110=EN 3.27volt Normal. U7710=EN 0.00 volt U7712=Pin 5 Pp3v3 = 3.29 volt - = Pin 4 PVCCEDRAMS0 0.00 volt U7712 and U7710 changed without result U7220=VIN=12.54 volt I am working but I think I have lost my thread.

    Sorry I forgot to write you I only wrote the ones with voltage😅 L7702 = 0.00 L7210/20 0.00 L8100 = 0.00

    Thank you 2informaticos. I managed to get the device in DFU revive it. That went well but I still need power for backlight on keyboard and picture on internal and external screen🥵. Trackpad is tippin.

    One last question for now:-) 2informaticos:-). I have read a post where you describe how to put a logicboard in DFU without the keyboard. I Can not find that thread. Would you be kind explain it to me? Thank you in advanced

    I've done something stupid :-). I have tested a new display on the A2159 mbp and suddenly I lost the screen and plug off the connector. since it can not boot more than to 0.330amp and drops back to 0.160 amp. And stats here. trackpad clicks and the fan turns. there is black screen. I have tried...

    820-01598 no restore T2

    I have exactly the same issue with a A1932 (mbp Air). I have not found a solution yet🤬. If I compare with iPhones with a 4014 error the problem could be a bad NAND. Could it be the same problem? (Reball NANDS?)
