Repairing a Dell LCD monitor can often cost more than the monitor is worth. Unfortunately, Dell does not repair monitors; it only replaces them while they are under warranty. Therefore, if your Dell LCD monitor malfunctions after the warranty expires, your best option might be to try to repair it yourself. If you must repair or replace one of the internal components of your Dell LCD display, you will likely have to open the monitor to expose the circuitry.

Remove the back cover of the monitor. Secure the monitor from both sides and insert the edge of a flathead screwdriver into the groove on the bottom of the monitor where the back cover meets the body. Gently pry the back cover upward and lift it straight up.
Remove the metal plate at the bottom of the monitor to expose the high-voltage connectors (pink and white wires). If you cannot remove the plate by hand, gently pry it away from the monitor with a flathead screwdriver.
Disconnect the high-voltage connectors by pulling the white plastic ends straight out of their sockets.
Remove the screws on each side of the monitor.
Detach the metal housing from the monitor to expose the circuits and other components. Grab the housing on each side and lift it straight up.
Tips and warnings
- Never work with electronics while they are connected to a power outlet. Failure to disconnect a power source can cause electric shock, potentially leading to serious injury or death.
- Exercise extreme care when prying off the back cover of the monitor. The monitor's cover is made of delicate plastic that can easily crack under excessive force.
