Default Issue with acer v173 CCFL inverter

Hi people:

This is not a repairing issue. Actually the monitor is perfectly fine. It is an acer v173. Thing is I am trying to transform it into a TV using an universal TV control board.

Well thing is am trying to reuse the inverter from the monitor board. It is combined with the power source. I am not sure if I can get 12v from it but was thinking to at least reuse the monitor inverter and save some money while learning.

So I measured the pins and saw the original controller board was sending about 2.8v to one pin to turn on the inverter.

So I took some resistances and made a voltage divider out of the 5 volts it sends from the power source.

Thing is it turns on but goes sort like flickering and eventually turns off.

Now strange thing is if I connect the controller board with only +5v and ground (rest of the pins disconnected) once I apply the voltage to the on pin it turns on without problems. If I don't stop sending the voltage and turn off the controller board it goes into the flickering thing.

So I am wondering what could be the cause and trying to get some hints here.
