Samsung LTA320HF05 - change of LVDS data format from VESA to JEIDA.

[Tovi]

Panel : Samsung, LTA320HF05
T-CON : S120BM4C4L V0.7, IC591 (LAUC041T0B-Q2)

Greetings to all
I have a 32-inch LED panel brand Samsung, model LTA320HF05, with a T-CON S120BM4C4L V0.7 and controller, the IC LAUC041T0B-Q2 on board.
Everything works perfectly, but I need to set the LVDS data format from VESA TO JEIDA in hardware mode on the T-CON (the firmware of the TV card does not allow this).
On the net I can't find information or diagrams of both the panel, T-CON and the IC Controller.
If anyone has such schemes, or information on how to make this setting and wants to share them, thank you.
Regards

У нас что, теперь итальянцы рулят? Или особо одаренные будут демонстрировать полиглотство?

I thank Rammer for the valuable document.
I therefore tried, as indicated, to work on pin 45 of the CON1 connector (51 pins).
I followed the track that starts from this pin, and this ends on pin 82 of the LAUC041T0B-Q2 controller,
and along the way it provides the possibility of inserting a resistance towards 3.3 volts.
I then disconnected the connection to GND (GND that comes from the LVDS cable), and inserted a 1K resistance towards 3.3 V,
but I did not get the change from VESA TO JEIDA, but the appearance of a "misty" image (see photo).

The document indicates: Notes (1) LVDS OPTION: If this PIN HIGH (3.3V) → Normal LVDS format, LOW (GND) → JEIDA LVDS format
but in reality if at GND (as it is natively), the format is VESA (The tests I am carrying out are with a universal TV card T.S512.69, fully functional.

For completeness of information, there is a 2/4 channel LVDS converter between the TV card and the T-CON.
Do you have any further tests in mind?
Thank you

Извините, что пишу сюда, не нашел как отправить ЛС, или прав на форуме не имею ещё.
Вижу, что у Вас есть доступ к редким даташитам на матрицы. Можете помочь с даташитом на матрицу от Samsung?

на матрицу от Samsung?

-сам понял, что спросил? Только у дебилов все матрицы самсунг одинаковые.

Vlad-1966, я ждал от него лс, и там уже все подробности. Но ты молодец, любишь острить, давно тебя знаю, советы твои помогают, да. Но язвишь прямо как я иногда
