If your LG Digital Signage displays no image, start by ensuring the power cord is securely plugged into the power outlet. Next, verify the signal cable connection. Also, press the INPUT menu on the remote control to confirm the correct input signal is selected. If the signal from your PC's graphics card is outside the product's vertical or horizontal frequency range, adjust the frequency range according to the specifications in the manual.
