Default Re: Issue with acer v173 CCFL inverter

You can leave the PWM wire unconnected which will drive the lamp at full brightness at all time which is not a good idea.
You have to come up with circuit to drive the transistor with PWM signal based around 200 or 300 Hz and able to adjust the pulse width betwen 35~100% range.
