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

LVDS от VESA TO JEIDA в аппаратном режиме

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
