I've tried booting the iCloud locked board on the external monitor, using the same type-c/hdmi adapter i used on the faulty board, and its showing correctly the screen, so, unfortunately you're right, its about graphic part of cpu, so i guess this is a no-fix case

I get a blurred image when connected to external monitor, i tried several type-c-hdmi adapters

So, i bought a donor board, its icloud locked but fully functional, now i know the display is 100% working, i've also read the display FPC values and all are the same...

Im focusing now on i2c lines, like spi_tcon_cs_L, unfortunately my board is 820-02385 and there is not diode values references on openboard

LID signal is 1v2, no luck, the problem is not about the LID

Oh, you are right, i misunderstood the meaning of the line, so its an enable line (1v8) to enable a 5v rail. ok, got it. I dont have 1.2v on the lid signal, its about 1v, i think its a bit low, i gonna try to force it to 1.5 and if nothing happens i will try 1.8v and post result, thank you.

On closed screen i get 0V, open screen 1V, the schematics says this line need 1v8 for enable, should i try to emulate 1v8 ?

I found the LID sensor in the corner on the screen is broken, does the macbook m3 need it fully working to show image on screen ? usually disconnecting it the device just bypass it, but im not sure

edp fcp are all good, but i found this live from EDP_BLC_5V_EN should be 5v and i have 1.8v UP710 get enable from LCD_PWR_EN wich comes from pmic, then it generates all the edp lines, the lines are all present at 1v8 but EDP_BLC_5V_EN should be 5v right? it get 1.8v there

The system has been flashed and the external monitor is showing the login screen, so the mac its 100% working, i gonna try to disassemble the old monitor and check the t-con now, but if you have any suggestion would be very appreciated, thanks

Since when trying to boot on external monitor - sometimes i get a grey empy image (the one of the recovery), sometimes i get recovery screen with the top banner - it may depends on the type-c/hdmi adapter but im not sure... So i'm trying to restore the device with Apple Configurator 2 to check...

LPD_INT_HPD is present with 1v2v

The enable line is present with 1v8

Hi and thank you very much for these precious informations, tomorrow i will do all these checks. thanks

When the damage occurred, i remember the backlight of the keyboard flashed some times, then turned off, now, powering on the machine, the backlight on the keyboard stays off, always.
