How to Fix My Dell Inspiron E1705 Screen

Published on February 23 2012 by delllaptopparts

The Dell Inspiron E1705 computer features an Intel Core Duo T2500 processor running at 2 GHz, 256 MB of RAM, 1 GB of DDR2 SDRAM, and a 17-inch display. This display can suffer from a number of problems ranging from monitor brightness issues to backlight failure. You can self-diagnose these problems and fix your Dell's screen without any outside assistance, even if you lack any experience with computer repairs.

Check the monitor brightness of the Dell Inspiron E1705 screen if it appears too dark or completely black. The brightness may have been reverted to its lowest setting accidentally. Use the brightness keys on the top left of your keyboard to toggle the brightness.

Power down your Dell Inspiron, disconnect the power cable from the back of the unit, and close the lid.

Turn the Dell laptop over. Locate the horizontal battery outline on the top center of the device. Below this is a release mechanism. Slide this battery release to disengage the Inspiron's battery. While sliding the release, pull the battery out. The battery may need to be replaced if it has aged and can no longer hold a charge and power the screen.

Slide a new battery into the spot vacated by the old battery. If the new battery does not fix the problem, remove it so that no battery is installed before going forward.

Turn the computer back over and open the lid so the screen is visible. Look along the bezel of the screen. This bezel is the plastic perimeter that surrounds the display. You will see a number of round seals or caps along it. Each of these conceals a screw that must be removed. Pry under the edges of the caps with your fingers or the tip of a flathead screwdriver and pop off the caps.

Remove each of the screws beneath the caps with your Phillips screwdriver. Gently pry the bezel off.

Check the bottom center of the exposed screen. There will be a rectangular green board stretching across the bottom of the display. This is the inverter board. There is a cable on either side of the board, and a connector on each of the board's ends. If either cable is loose from its connector, you must replace them to restore video or backlight functioning to the screen.

Lift up slightly and very gently on one side of the connector. This should only be a few millimeters, otherwise you may break the connector. Slide the cable back into the connector, then press down gently on the top of the connector to set it back into place.

Replace the bezel, screws and caps.
