While these issues may seem deeply technical, you can troubleshoot for and fix these problems even if you have no previous repair expertise. All you'll need is a Phillips head screwdriver to complete these repairs.

Ensure the Dell E151FP LCD monitor is plugged into the power outlet. The main black power cord that runs out of the back of the monitor cannot be loose from the wall socket or surge protector. Additionally, try another wall outlet in case the current one is blown.
Check the VGA cable of the Dell E151FP LCD monitor. This cable connects the LCD monitor to the computer. It is a large, flat, multi-pin connector that connects into the “VGA” port on the computer. If this cable connection has not been made between the monitor and computer, no information will display on the LCD screen despite the fact its power indicator light will be on.
Check the monitor brightness settings of the Dell E151FP LCD monitor if the screen appears too dark or seems not to be functioning at all, despite the power indicator light shining and the VGA cable being plugged in. Brightness settings can be found on the top of your computer’s keyboard, just above the numeric keys, or on the bottom face of the Dell LCD monitor itself. If the brightness was reset to its lowest setting, the monitor would have appeared completely dark.
Check for backlight failure on your Dell E151FP LCD monitor if the brightness adjustments do not work. Power down the monitor and disconnect it from all power sources. Look along the bezel of the monitor. This is the plastic piece that surrounds the actual screen. Plastic caps conceal the monitor’s screws. Pop these caps off with your fingers, then remove the screws with a Phillips head screwdriver.
Pry the bezel gently off with your fingers now that the screws are removed. Set the bezel aside.
Locate the monitor’s inverter cable. This black cable governs the operation of the monitor’s backlight. It can be found sitting atop the inverter board, which is a horizontal strip found at the very bottom of the now-exposed display. The inverter cable plugs into a socket on the inverter board. If it is loose from this socket, it must be plugged back in. Lift up slightly on one edge of the socket just far enough to slide the inverter cable back in. Press down on the socket to lock it back down.
