Re: LG 32LN520B TV power up problem help requested

I would really appreciate any help, because it is just a backlight issue... it might be simple.

But, I can always replace the original LED strips with generic ones from Ebay, and use a separate controller

Thank you for any help.

Re: LG 32LN520B TV power up problem help requested

Hi all,

I have the exactly same TV and the backlight is not working.
I can hear sound as normal and see that the panel is working if using a flashlight pointing to it, but the backlight is off.

So the problem should be the LED backlight power supply. I used my multimeter to check the voltage at LEDs connection pins.
Please see by yourself:

At each time the voltage goes up, I can hear a tiny click from the PCB...
