Put a jumper on the motherboard between FB_TRDY_1 and FB_TRDY_3 and then you can determine which half of the panel is not working.

In which area do I find these acronyms? I would like to avoid making changes to the card purchased (paid a lot) so that I can return it in the worst case

Post a high-quality photo, close-up, where the connectors for connecting lvds cables are located.
I understand that you have the same behavior as on your own motherboard, on the new one you purchased.

FB_TRDY_1 and FB_TRDY_3

what happens once connected?
risk of damaging the new card?

Nothing will happen to your motherboard, this is so that the motherboard understands that you have two lvds cables connected, with a jumper it will now display an image on either side, with one cable disconnected. And you can determine which half is not working for you.

And all these manipulations must be done with the TV turned off from the outlet.
Why, put a jumper and disconnected one cable, checked, connected the first, disconnected the second and checked again.

okay
in this way I exclude that the right panel has problems?
if the panel is good, do I have to change the correct card?

Re: samsung ue55mu6192u dead signal LED

Well, you check, then it will be clear, maybe the T-CON (25Q80) firmware is not working or the panel for it does not match.

I let it test for an hour before putting the lid back on
Do you think I need to make some changes in the service menu?

If the panels (matrices) were the same, then nothing needs to be changed.

Hello,
I suspect I have a problem with IC1604 dump integrity too.
Can anyone (lotas?) check and correct if needed my dump?
All info are in photos attached.
