How to troubleshoot no picture on Lightware Extender?
- CChristopher AndersonAug 22, 2025
If your Lightware Extender is not displaying a picture, begin by confirming that all devices are correctly powered. A simple unplug and reconnect might solve the problem. Ensure all cable connections are firmly in place. Specifically, for optical cables, verify they are connected to the correct 'channel A' and 'channel B' ports. Using Neutrik OpticalCON Duo multimode fiber cable is recommended. If the fiber optic cable connector is contaminated, clean it carefully. If the Signal Present LED is off on the transmitter, there's no DVI signal; check the source and cable. Similarly, if the Signal Present LED is off on the receiver, check the source and fiber cable. If the EDID Status LED is red, choose a valid EDID. If the data rate is too high, select an EDID with lower resolution.
