Smile LG Flatron W1946 wiring inverter AIP-0198

Hi,
my problem:

I need schema inverter to monitor.
Flatron W1946
Power chip -3BR1765JZ
CCFL inverter -MP10072ES
Mosfet -APM4511GED

inverter no voltage on the output of the lamp
Power works and have all the necessary voltage connector.
I can not find a scheme inverter chip MP10072ES
I looked at the service manual "LG" for this model but in the scheme only for VGA module-inverter for no
would be very grateful if anyone has Schema or advice chip is compatible with MP10072
thank you

Are you getting the INVER-ON (or BL-ON) command signal from the Main logic board to turn on the backlights inverter circuit?

Are the backlights totally dead or do they flash on for a second when you turn on the TV?

CapLeaker:

sorry I did not for some time now (forum)

flash a second


I solved it with a new pipe By changing CCFL
but still has a problem
I get a picture on the screen, raise the Windovs all ok
turn off the PC and turn on again when you can not pick up the image windowsa-
flashed lights, logo appears, "LG", and the fit-not hold up a picture of the PC Windovs
when you disconnect the flat cable with a VGA module on the LCD screen has a bright screen
