The board suffered liquid damage mainly on PPVOUT_SW_LCDBKLT, which corroded the tracks and also the pins of the lvds cable I replaced the lvds connector and used a 2010 model cable but on PPVOUT_SW_LCDBKLT I get 24 V only the led on the back but LCD does not display anything even the white screen, I also get PP3V3_LCDVDD_SW_F and the LED_RETURN

So your problem is related with the image; backlight is correct.
Check L9080 and continuity of all LVDS_IG_A traces.
