What to do if no image is displayed on my LG 55EJ5D-B?

If no image appears on your LG Digital Signage display, start by checking if the power cord is securely plugged into the power outlet. Also, ensure the FPC extension cable is properly connected between the cable coming out of the panel and the signage box. Verify the signal cable connection and press the INPUT menu on the remote control to confirm the input signal. If the signal from your PC's graphics card is out of the product's frequency range, adjust it according to the specifications in this manual.
