## Questions & Answers

**Q: Previously Working TL/SL LCD Fans Now Uncontrollable (e.g. 2 or 3 fans, one screen fails to respond)**
A: 1.Confirm power source SATA or an external PSU. 2.L3 latest version. 3.Uninstall it from device manager, shut down, unplug and replug the fans, then restart to force Windows to rescan USB devices. 4. Remove USB cable and clean USB path.
