Re: LCD LG 32LD320 :sound ok, no video

On the fuse is number 20 that means 1.5A or similiar ? Thank you.

Hi Guys,
problem is backlight of LG 32LD320-ZA. I see that the LCD is working correct(check with light), sound is also ok(assume that mainboard is correct). It seems that the power is also correct on pins to inverter is correct 24,5V but on other pins: Error = 2.2V, PWM_DIM = 0V, INV ON/OFF = 3.3V, BRI = 0V
I found out that the black fuse on inverter (P1190298.JPG) is bad 60kOhm

Is the problem truly on backlight inverter or could be something different?...

Hi Guys, I have similar problem like in this thread, therefore I don't create new thread. Problem is on LG 32LD320 backlight is off, I see that the LCD is working correct(check with light) sound is also woking(assume that mainboard). It seems that the Power is also correct on pins to inverter is correct 24V but on other pins: Error = 2.2V, PWM_DIM = 0V, INV ON/OFF = 3.3V, BRI = 0V
Is the problem truly on backlight inverter? Could you help me to how to proceed?

Thank y...
