yes im using dat0 adapter but i removed it now, it was working, playing my switch turned off and removing the mod showed me that the display wasnt working, what was working was just the dock mode, i resoldered the mod while the display was coming cause i tought that was the problem

Hard to follow your word. You mean now works? the two traces is ok to cut.
If you cut those two test pad traces, test pads wont effect on the display while messing with dat0 adapter.
if you didnt cut those two test pad traces, bad soldering around test pads might short LCD drive chip to ground while installing/removing dat0 adapter.

The test pad traces are cut and the trace beyond the photo is all clean, so that dont influent the display.
Do you have any idea of what could it be? I read it could be related to the chip behind the console near the emmc, do you know how and if I can test it?
Thanks for the help and sorry for bad english, i tryied to write things as clear as possible.
