Repairing the NEC LCD monitor is a task that doesn’t need to be outsourced to a computer technician or an electronics repair professional. While the monitor may occasionally suffer from inverter cable problems, related backlight failure, LCD cable issues or simply maladjusted brightness settings, you can troubleshoot and repair all of these problems yourself, even if you’ve never tackled monitor repair previously. You will only need a Phillips head screwdriver and maybe a flathead screwdriver and guitar pick, although the latter objects are not required.

Check the monitor brightness settings for the NEC LCD monitor. It’s possible that the brightness was accidentally turned all the way down on the NEC, resulting in a display that is completely black. There will be brightness keys on the bottom of the NEC monitor, and there should also be brightness keys on the top of your numeric keyboard. Adjust the brightness if necessary.
Power down the monitor and your computer if the brightness adjustments do not work. Disconnect the monitor from the computer.
Remove the screws along the side of the NEC LCD monitor’s bezel, which is the plastic piece that runs around the actual screen. Depending on your NEC monitor model, these screws may be covered with a plastic seal or cap for aesthetic purposes. You can pop these off with your fingers or by using the edge of a flathead screwdriver.
Remove the exposed screws with a Phillips head screwdriver.
Remove the bezel from the NEC LCD monitor. The bezel will still be held partially in place by small plastic latches that reside between the bezel and the rest of the monitor’s assembly. You can run your fingers along the perimeter of the bezel to disengage the latches and pry the bezel gently free, or you can use the aid of a thin object to wedge between the latches, such as a guitar pick. Avoid using a metal object between these latches, however, or you could damage them.
Set the bezel aside.
Check the inverter cable of the monitor. This black cable will be on the very bottom centre of the NEC LCD monitor, and should be connected to a socket on the inverter board that lies just below this cable. If it is loose from this socket, the backlight of the monitor will not operate properly. Lift up on the edge of this inverter cable socket, slide the cable back in, and press down on the socket to secure it.
Remove the metal brackets on either side of the NEC LCD monitor if the inverter cable repair does not alleviate your issues. There are two screws in each bracket that must be removed with your Phillips head screwdriver.
Pull the NEC LCD monitor’s screen slowly away from the back casing, just enough to reveal the LCD cable that runs out of the back of the screen. This cable should attach to a socket almost identical to the construction of the inverter cable socket. If it is loose from this socket, this is your problem.
Lift up on the LCD cable socket and slide the LCD cable back in. Press down on the socket to secure it once more.
