How to Repair a Flat Screen Monitor

by Contributor

When your flat screen computer monitor goes on the blink, there is a good chance it needs to be opened up and worked on. If you don't have enough money to take it to the repair shop, you may be thinking about throwing it away and buying a new one. You don't actually need to do this, however, because it's possible to open up your monitor on your own and repair any problem other than a cracked or shattered screen. And the best part is that most monitors can be repaired in a short amount of time.

Step 1

Turn off the monitor, unplug it from the computer and disconnect it from its power source.

Step 2

Turn the monitor over and slide the monitor stand from the base of the unit to remove it. If there are screws securing the stand to the monitor use the Phillips screwdriver to remove them.

Step 3

Remove all screws from the back panel of the device with the Phillips screwdriver. Gently lift the panel from the rear of the unit.

Step 4

Locate the long rectangular backlight bulb attached to the rear of the screen. Make sure the screen cables attached at the end of the bulb are securely attached. If the backlight bulb is blown, unplug the cables, remove it and replace it with a new one (available from your computer retailer or online). At this point you should try out the monitor. If that didn't fix the problem proceed to the next step.

Step 5

Turn the monitor right-side up and remove any screws on the screen bezel (frame surrounding the LCD screen).

Step 6

Insert the tip of your flat-head screwdriver in the seam between the screen bezel and the body of the monitor. Gently work your way around the bezel until it separates from the monitor.

Locate the rectangular green inverter board directly under the LCD screen. Make sure the cables connected in the ports at either end of it are secure. If the inverter itself is broken, replace with a new one (available from your computer retailer or online) and reassemble your monitor in the reverse order you took it apart.
