From the picture it's not good to see, I have to look at the schema
OK, the problem is I don't know where can I find the schema, sorry. I have been looking for it in the service manual but it seems that it doesn't appear. Anyone know where could it be please?

Hello again. As I told you before I tried it and I am almost sure that's why my television was bricked, so I strongly recommend you (and other users) not to try that DNS server (again).

Thank you for the useful information. I removed the stickers in my mainboard and now I can confirm that those two chips are the same than Erdem on his UA40D6000 (viewtopic.php?f=23&t=2519): SDIN502-2G and KFG1GN6W2D.
I've been looking for the Internet and I found other people in a similar situation than me. For example:
https://www.plcforum.it/f/topic/210322- ... nt=1540519
I repeat the same question as before: wouldn't be possible to extract that BGA chip, reprogram it or replace it with another new BGA chip (same model) in order to avoid all the mainboard replacement? I've found firmware dumps in some russian pages like http://tel-spb.ru/remont-tv-lcd/samsung. It seems that these files were extracted using some programmer. In fact I think in other russian forums are talking about this (http://www.kenotrontv.ru/forum for example). The problem is I can't understand (read or write at this momment) in Cyrillic alphabet. Anyone has more information about this possibility please? Thanks in advance.
