After I turn on the power, the panel of the machine is not bright or very dark. I cannot see the characters clearly. How to deal with it?

1）The power source has no voltage. Check the power source.
2) The setting of the brightness of screen background is not correct. Press CTRL+L to adjust the brightness.
