How to fix no image on LG 43SM5C Digital Signage?
- LLaura BerrySep 3, 2025
If no image appears on your LG Digital Signage display, first ensure the power cord is securely plugged into the outlet. Then, check the signal cable connection. Also, press the INPUT menu on the remote to verify the input signal. If the issue persists, your PC's graphics card signal might be outside the product's vertical or horizontal frequency range. Adjust the frequency range according to the specifications in the manual.
