Hello, If there is a complete darkness on the screen, it is likely that the problem is on the card that responsible for providing backlight to the screen. Known as invertor. Sometimes the causes are: 1 loose contacts across the card. 2 the main ic that is number begins with OZ .3 More rarely missing of the 24V voltage that provided to the invertor, in this case you should check the power supply. I hope it was helpful!
Let me know if more help is needed.
