What to do if the Lenovo THINKVISION LT1421 Monitor power indicator is not lit and there is no image?
If the power indicator is off and there's no image on your Lenovo Monitor, first, ensure the monitor is plugged into a working electrical outlet. If it still doesn't work, check that the USB cable is properly connected to both the monitor and your computer.
Why do one or more of the pixels appear discolored on my Lenovo THINKVISION LT1421?
