Lg 32le4900 no video,sound and backlights
The tv turns on but the screen is black and no audio.When the mainboard cable is connected to power supply at a certain angle(ie '/') , the backlights will turn on but still no video and sound. I also checked blue connector pins powering the driver board when connected. I found out the drv_on pin voltage is missing , but found on error pin. Is it the mainboard is not sending signal to power supply turn on backlights? If so how do I rectify it? -
