A broken computer screen can be a major inconvenience, making it difficult to work or do anything on your computer. The good news is, you don’t necessarily have to spend a lot of money getting your computer screen fixed - you can actually do the repair yourself for free. Here’s a guide to help you repair a broken computer screen step by step.
Identifying the Problem
Before you can start fixing your broken computer screen, you need to identify the problem. If the screen is completely black, you could have a problem with your computer’s power supply. If the screen is still lit up, but isn’t displaying any images, you could have a problem with the cable or the graphics card. You might also have a problem with the backlight. To identify the exact cause of the problem, you’ll need to disassemble the screen and check the components.
Gathering the Tools You Need
To repair your broken computer screen, you’ll need some basic tools. You’ll need a screwdriver, a pair of tweezers, and a can of compressed air. You’ll also need a few other tools, such as a static brush, a soldering iron, and a multimeter. Make sure to have these tools on hand before you start the repair.
Disassembling the Screen
Once you’ve gathered the necessary tools, you can start disassembling the screen. Start by removing the screws from the back of the monitor. Once you’ve done that, you can carefully remove the bezel, then disconnect the cables. Don’t forget to remove the ribbon cables from the LCD panel. Once you’ve done that, you can remove the entire LCD panel from the back of the screen.
Checking the Components
Now that you’ve removed the LCD panel, you can start checking the components. First, check the power supply by checking the voltage with a multimeter. Next, check the inverter board by checking the voltage and making sure there’s no visible damage. Then, check the backlight by connecting it to a power source and making sure it’s working properly. Finally, check the LCD panel for any visible damage.
Cleaning the Components
After you’ve checked the components, you can start cleaning them. First, use a static brush to clean the power supply and the inverter board. Then, use a can of compressed air to clean the backlight and the LCD panel. Make sure to clean all of the components thoroughly before reassembling the screen.
Reassembling the Screen
Once you’ve cleaned all of the components, you can start reassembling the screen. Start by connecting the cables and ribbon cables to the LCD panel. Then, carefully reattach the bezel and the screws. Finally, turn on the computer and make sure the screen is working properly.
