However, if you see lines, black spots or discolored areas, or the screen won't light up, your LCD screen is most likely damaged and will need to be repaired.
Step 1: Tools Needed
This fix can be performed using a minimum of tools. You need only the tools necessary to disassemble the device (in this case only one screwdriver was necessary), a hot-air gun (a powerful hair dryer may work), and a pencil eraser.
Step 2: Disassembly
Disassemble the device to expose the LCD. Obviously, this step will vary by device. If you are having trouble getting your particular device apart, try Googleing "'yourdevicename' disassembly".
Step 3: Prep the Screen
Prepare the screen for repair by exposing the ribbon cable on the backside of the screen. In this phone, there is a plastic clip holding the LCD that must be temporarily removed. A plastic-coated paper clip is a handy for holding the LCD down while you work.
Step 4: Repair the Connections
Using LOW heat (you do not want to melt the ribbon or the solder on the board), slowly heat the ribbon cable where it is connected to the mainboard to soften the glue. At the same time, gently but firmly rub the connection strip with the pencil eraser. Tips: 1. Try to avoid directing too much hot air onto the LCD itself as this could damage it. 2.
Step 5: Results

What happens if your monitor is damaged?
If your monitor has a visible crack, a large discolored area, or a black/multicolored spot that doesn’t align with the pixel grid, it’s been subjected to physical trauma and the LCD panel is damaged. There’s nothing you can do here: even if your monitor is within its warranty period, it almost certainly won’t cover physical damage. You could try to replace the LCD panel itself, but since the replacement part will be almost as expensive as a new monitor anyway, you might as well start shopping.
Why is my screen showing the wrong resolution?
If your screen is suddenly showing the wrong resolution for your desktop—which is indeed a pretty big deal for any PC user —the most likely culprit is your graphics card. It’s probable that either the software component (the graphics driver) or the graphics card itself is where the problem is located. Updating the driver usually fixes this problem, though a new graphics card might be in order.
Why does my monitor make a whine sound?
The most common problem that can cause a buzz or whine noise in a monitor is an issue with the backlight, usually with the compact florescent tubes used for lighting in older models. (This design has been largely superseded by LED backlighting, but there are still plenty of CFL-equipped monitors in use.) Buzzing can occur due to problems in power regulation to one or more bulbs. Try adjusting the brightness of your screen up or down to see if the noise dissipates; of course, this can be a less than optimal solution if you need your screen brightness at a specific setting.
What is dead pixel?
A “dead” pixel is a single dot on your LCD screen that doesn’t illuminate, showing up as one or more black squares. “Stuck” pixels are similar, but instead of showing black they’re stuck on a single color that doesn’t match the computer screen’s image, typically either red, green, or blue.
Why is my screen black?
Black or single-colored lines on LCD screens are caused by a lot of different issues, but if the standard fixes outlined in the flickering section above don ’t fix them (check your video and power cables for problems, install new drivers), it’s probably a physical defect in the screen itself. Try your monitor on another computer or laptop to see if the problem persists; if it does, you’re probably looking at a replacement, since the error is almost certainly in the LCD panel (the most expensive component of the monitor).
Why is my monitor flashing?
If your monitor’s screen is often flashing or stuttering, there are a few different problems that you could be facing. It might be something as simple as a loose or faulty video cable. So first, tighten down the cable on both the monitor and the computer end (making sure to completely tighten any retention screws, if your cable has them) or simply replace the cable. The same thing goes for the power cable: make sure it’s secure at both ends, and if the problem persists, replace it if possible.
Why does my monitor turn off?
A monitor that periodically turns itself off might not be getting sufficient power from the outlet or surge protector —again, check your home’s circuit breaker and make sure the power cable is correctly plugged in. It’s also possible that the internal or external power converter (the latter will be a box or “wall wart” on the power cable) is overheating. Carefully check the casing of the monitor itself or the power adapter; if either is too hot to touch for more than a few seconds, they need to be replaced.
