To troubleshoot a missing image on your LG Digital Signage, first, ensure the power cord is securely plugged into the outlet. Then, inspect the signal cable and use the input menu to verify the input signal. If the issue persists, the signal from your PC's graphics card may be outside the product's vertical or horizontal frequency range. In this case, adjust the frequency range according to the specifications outlined in this manual.
