Hi, i have my own (820-00239 i think?) i tried to test another lcd assembly, and when i try to reassemble everything, it doesnt boot at all, there’s apple logo but loading bar doesnt increase at all, i tried to boot to external, but it freeze at boot option with a bit of red tint at the lcd, caps lock doesnt work at boot option, so its not lcd problem( assuming caps lock light work at boot option ) does this have something to do with fmdf from mouser/digikey?

"does this have something to do with fmdf from mouser/digikey?"
I don't understand the question.
Did you chabge some chips on the board, or just tried another LCD assembly???
Disconnect LCD assembly and test the board alone.
Use USB-C to HDMI adaoter, or just check for continous USB activity; or Caps Lock reaction.
Possibly knocked off components in the LCD swap process, or broken traces...

Sorry i mean fdmf chip ,
Let me get this straight
The chronology; i bought this board from someone refurbished, i used this board to test another lcd assembly, after reassemble , it stuck at apple, i keep trying to restart and it suddenly freeze and i seen some red artifact at the screen, and its the last time i have seen image on the screen.. and it end up at only backlight, no image, without external video , no caps lock reaction too
I open the board and see some corrosion on cd3215 which i mentioned above, but that shouldnt have anything to do with image ? Because i have 20v. Does this have anything to do with dead cpu output or this is no brain?

I still don't see the reason of that question.
Did you change any FDMF5808 chip???
If not, why menrioned an online store then?
Video artifacts can be generated by RAM, or CPU...

Heat RAM, or/and CPU; use quality flux.
