I have checked voltage on LED driver IC coil. It is 3.9V when lcd disconected and 2.9v when lcd connected. What is the correct voltage for backlight led ? I traced 2.9v on upper lcd pcb after flex. On lcd itself, there is flex with 2 wires only, i think it is led connection flex, there i measured 0v. What can I do to fix the backlight, thanks in advance
