SOLVED: A2338 820-02020 Heavy liquid damage, melted LVDS connector on T-conn board. No Backlight

[it-solve]

Replaced LVDS cable to the board, and tested with spare LCD, I can see faint light but no backlight. Heavy oxidation around UP800, QP801; CP951/2/3/7
Melted LP610, replaced.

Voltages with connected LCD:

PPV5_CAM - 5.17V
PPVOUT_LCDBCKLT - 0V
FP800 intact, as expected - 12V
BKLT_EN_R - 0V
LCDBKLT_FET_DRV - 0V

Before I replace UP800, anything else to check?
No shorts in the area.

Check all resistors and traces in the backlight area.

If I get 53V at PPVOUT_LCDBKLT, the boosting of it should be working right?

 

[2informaticos]

53V is high too much.
There is no connection with LEDs strip.

Thanks, found the loose connection
