Yes, i should started a new thread. Sorry! Thanks!

Hi, I don't know if it is better opening a new thread... I have a 820-00138-A board, with similar original problem. U7320 was shorted. After read various threads, i know i shouldn't use FDMF6808N from Aliexpress. But just in case, and because i don't have the other IC versions, i replaced...

Already tried it, but still with the same behavior. I'm not gona loose more time with this board. Thanks 2informaticos!

Any tips of how much heat and how much time?

Yes, i'm working on the desk only with the board and power supply. I forgot to mention, that i already tried a known good bios file and IC. PLT_RESET_L = 3.3V stable

Yes, stable 0.953V

Hi, This machine stopped working suddenly. Like a wrote in the title, the amperage goes to 650mA and after a few seconds drops to 400mA. CPU and SSD warm a little, but nothing special. Apparently, sound alike the Logic Board is going to boot normally. But there's no image on display; no image...

Hi @2informaticos, Thank you, for your reply. I tried the revive, but still the same. I've been thinking a little more about this problem and analyzing the schematic. In practice the conclusion I came to is that the external monitor is being identified as a secondary monitor. That's why, only...

Hi, This is my first M1. I feel a little lost and not knowing where to start. The machine had a liquid damage, next to UC300; UC710; JR940 and UP900. I did reflow to the IC's. In the measurements I didn't find any low resistance value (short circuit) and the IC's output voltages are correct...
