820-3115-b no post , fan spin

Hey all,
I have a 820-3115-b that was worked on, I have not history for it .

Found a lot of flux by the keyboard ic and EFI chip was definitely removed and resoldered.
It powers on , fan spin , green light, won't beep without ram .
Did SMC reset, did pram ,no visible water damage.
Removed EFI chip , made a backup and worth chip with good working bios of same exact model board.
Not an expert but was told I might need a bin file with clean ME ? Not sure what that is .
Any ideas where I can start diagnosing this issue?
Thanks
