has it a separate tcon? i think yes, if so i would get a replacement one, only from cracked panel

[adam brown]

Hi no its a av board/tcon all in one on these

All modern Samsung TVs (4K) have T-CON built into the motherboard.

So there is an internal main board and external one, then i would change internal one.. bye..

who said that.. there are different panel connection with MB.. some with 4 ribbon,, other with only 2 and the last with 6 ribbon... so show you boards inside to see what you have... and did you disconnect the U ribbon on buffer boards left and right a time to see 3/4 picture?

Not all. I found at least one B4

Yes, but they already come with a very large panel diagonal... such t-con no longer fit on the motherboard.
