I have an 820-00840, with very minute signs of liquid damage around the SSD (logic board is perfectly clean)
It gets all power rails, yet never posts, and V-core remains high at 0.9V (these boards go a little lower when the post, maybe to around 0.75V)
I have tried a new EFI with clean ME (known good file) and had no changes.
I dont know where to look now, i think the CPU could be gone?

Was there liquid on the LCD cable or by the CPU controller fets? If so RIP CPU

Nope, none in that area at all, guess it coulda got into the TCON board somehow. Probably CPU, i would really like a good source of reasonable CPU's. Pulling U series chips of a scrap board is a waste of time as they always warp under rework (no matter what you do!)
