when mainboard is unplugged - connector CNM803 (then the LED backlight is switched on)
1. F/C 0,26V
2. A/D 2,67V
3. A13V 12,7V
4. OD_UD 3,53V
5. A13V 12,7V
6. BLU_PWM 3,11V
7. A13V 12,7V
8. POWER ON/OFF 3,86V
9. A13V 12,7V
10. GND 0V
11. GND 0V
12. GND 0V

If I connect mainboard then the backlight is turned off and there...
