If no image appears on your LG Digital Signage, first ensure the power cord is properly connected to the outlet. Then, adjust the brightness and contrast settings; the backlight might need repair. Check that the signal cable between your PC and the signage is securely connected and that the correct input signal is selected in the input menu. If the signal from the PC is out of the vertical or horizontal frequency range, adjust the frequency range according to the specifications in the manual.
