[daviddrf]

if it were Weltrend I know from experience that neither the LED does not come on you.But everything is possible.If they were an eeprom, I could have sent you the programmed ones.You would have exchanged yourself too.

Thank you Michal for your help. What of this two components is "Weltrend"?:

oneNAND = KFG1GN6W2D
eMMC = SDIN502-2G

Thank you again.

Not one. Weltrend is chip WT61P .....

Aha, OK Michal, thank you for the information. So the problem is that we don't know what specific component of my mainboard is defective due the symptoms I described. Is that right?

PD: I've found more videos of programs manipulating NANDs: https://www.youtube.com/watch?v=qeV3GRiXQKI

From your logs from exlink i am pretty sure your NAND has some problems whether boot partitions or kernel possible are unreadable. Thats why tv goes to bootloop.
