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

Re: samsung ue55mu6192u dead signal LED

Yes

it works, you see!
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?

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.

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?

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.

so made the jumper, can i connect both lvds or just one?

Re: samsung ue55mu6192u dead signal LED

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

I hope they go well

Re: samsung ue55mu6192u dead signal LED

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.

Re: samsung ue55mu6192u dead signal LED

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

Re: samsung ue55mu6192u dead signal LED

Switch off the panel (disconnect the cables from the motherboard) and check how the inclusion behaves.

I try to disconnect the flats that go to the panel and it stays on, I connect the antenna and I also hear the audio
I keep only one flat connected, the TV turns on and stays on but nothing appears on the screen, identical result in doing the test in reverse
in practice, when I connect both flats, the TV goes into protection and restarts continuously (even if there is audio and video for a moment)
