are you sure it s not a panel problem??
did you try another board just to make sure panel is ok??
did you try to force start mainboard without panel ?

no this is 4G emmc

my suggestion after you make sure mainboard problem is to try the 8gb replacement with the 4gb if it s not hard for you it will work.
even if my guess is not emmc problem maybe other hardware components like the reset ic it s a common problem in samsung

you mean you disoldered old 8g emmc and replace it with a good 4g from another similar board and didn t work?
if yes it s for sure not emmc problem .
did u try to take off the 25q80 and let the mainboard boot without tcon? maybe the problem is in tcon board section
