Answers :

The backlight on your display is not working, which is why you can dimly see the icons. Power for the backlight comes from a small board called an inverter which is mounted in the bottom edge of the display. It is a common problem for these inverters to fail. There are replacements available from vendors online, and installing the new board is usually a simple job.

In your case, the inverter problem may be due to the hinge trouble you have. The twisting force that damaged the case may also have broken the inverter board or caused its power connection to pull loose. Or the inverter trouble could just be a separate problem. You would need to open the display to check.

There are screws through the front and the front cover snaps in place. Remove the screws and the front cover and you will see the inverter board under the display panel. There are connectors at both ends. One is the power for the inverter and the other is the connection to the backlight. Make sure they are seated and that there is no visible damage to the inverter board.

Replacement hinges may also be available for your computer. Search for them and an inverter by looking for your paticular model.
Sounds like the inverter is blown or loose? if the screen is on but not lit up ok?
