If you've been experiencing problems with your Acer laptop screen, chances are it is a connection problem that lies with the inverter. The inverter is a circuit board that connects the backlight cable and the screen cable to the computer. You could pay a service technician to fix your screen for you, but it's actually possible for you to open up your screen in order to access the inverter. And the best part is that you won't damage your screen in the process.
Turn off your Acer, remove the AC cable and slide the battery out of its compartment on the bottom of the computer.
Locate the four screws on each corner of the bezel (frame) around the LCD screen. Use the tip of your screwdriver to remove the rubber pads over the screws and then remove the screws themselves.
Pull the bezel away from the screen by the sides and corners. You will notice the rectangular inverter board just below the screen.
Plug the two cables at either end of the inverter securely into their ports, making sure they are tight and fully plugged in. Replace the frame and screws and your computer screen should function properly.
