The back light on a liquid crystal screen shines through the coloured pixels and allows you to see the image displayed. The Dell Latitude D610 uses a cold compact-fluorescent (CCFL) light to illuminate the LCD screen. If the CCFL bulb burns out, then the screen will be barely visible in direct light. Dell provides the repair parts for the D610 as a full display that includes both the LCD screen and the CCFL back light in one package, so replacing the display will repair the problem of a broken back light.

Power off your Dell Latitude D610, unplug the computer from the wall and remove the battery. Lay out your tools, the computer and the replacement display on a flat, well-lit work surface. Open the computer so the back of the display lays flat against the work surface.
Slide your plastic prying tool under the Center Control Cover, which is just above the keyboard. Start on the right and gently pry up the cover, working toward the left. Remove the cover and set it aside.
Remove the two screws across the top of the keyboard. Set them aside. Lift the keyboard straight up and then rotate it clockwise 90 degrees. As you rotate the keyboard, keep it horizontal. Locate the pull tab attached to the keyboard cable on the right side of the D610's system board. Pull up on the tab to disconnect the keyboard from the computer. Set the keyboard aside.
Loosen the screw to the left of the blue pull tab at the top centre of the system board. Pull on the tab to disconnect the display from the board. Remove the four screws holding the display on the system. There are two on the right hinge and two on the left.
Set aside the main portion of the computer and lay the display on your work surface. Using the plastic prying tool, pry off the six bumpers around the edges of the display. This reveals screws. Remove the screws and set them aside. Grip the inside edge of the bezel with your thumbs and gently rotate it up and away from the display. Continue this around the edge of the bezel until it comes free of the display. Set the bezel aside.
Pull out the antenna cables that are clipped on the side of the display. Set them out of the way. Remove the four screws holding the display to the back. Pull on the tab to remove the cable from the bottom of the screen. Press in on either side of the top cable to release it and then pull it away.
Connect the new display panel to the top and bottom connectors and screw it in place. Re-clip the antenna cables on the side of the screen. Place the bezel over the display and gently press it so that it clicks into place. Replace the screws and screen bumpers.
Plug the display cable back into the system board. Line up the display assembly with the system and replace the screws. Reconnect the keyboard to the system board and rotate it back into position. Replace the keyboard screws.
Line up the Center Control Cover with the system and gently press it back into place, starting on the left and continuing to the right. Reinstall the battery and power on the computer.
Tips and warnings
- Lay down a soft, white towel where you can place the screws you've removed so they don't roll away and are easy to spot when you need them again.
- Use an electrostatic wrist strap or touch a grounded metal surface while working on the computer so that you don't produce a spark that damages the computer.
