How To Fix Pressure Spots On LCD Screen?
Basically, applying too much pressure to an LCD can cause dead or stuck pixels, and screens to flicker, and blur. These spots can appear in either white, blue, or red colors.
You may wonder if you can get rid of them permanently. It would be difficult to remove every type of spot, but some can be removed.
So, here we go! We’re going to take a closer peek at some of the different strategies that work for specific types of spots.
Method 1: Try This If You Have a White Spot on Your LCD Screen
White spots can occur due to a number of reasons. One reason could be an issue with the LCD screen itself. Another reason could be a problem with the backlight unit. In either scenario, the white spot appears on the screen. To fix this, follow these steps:
Step 1: Get Your Device Ready For The Fix
1. Switch off your TV.
2. Unplug the main power supply.
3. Unscrew its feet.
4. Lay the screen face down on a soft protective surface.
Step 2: Open It Up
1. Remove all the external screws and don’t touch any other internal components.
2. Take the back panel off the TV.
Step 3: Remove The Screws
2. Remove all the internal screw heads. It may be hard to remember exactly where each one goes, so it is best to either place them in some kind of logical sequence or write down which ones they are.
2. Remove the internal plastic cover to expose the speakers.
Step 4: Remove The TV Speaker Carefully
1. Jiggle the speakers gently until they come loose.
2. Unplug the speakers from the circuit board, and then remove them.
3. Unplug the ribbon cable on the circuit board.
Step 5: Remove The Protective Case of The Panel
1. Use a flathead screwdriver to remove the metal protective cover and expose the bottom circuit stops.
2. Carefully unclip the bottom circuit stops.
Step 6: Remove The White Sheet From The TV Panel
1. Gently lift the TV screen onto its side.
2. Do not remove the frame that borders the front and edge of the TV screen.
3. Place the TV face down again.
4. Lift the back of the TV and separate it from the screen.
5. Take the screen/display panel away.
6. Unclip the plastic frame. Be very gentle as the plastic is fragile.
7. Take the plastic frame away so the white sheets can be removed.
Step 7: Attach All The Loose Lenses To The Lights With Glue
1. Now lift the white sheets to expose the plastic circular lenses. These are the bits we need to fix—Finally!
2. Remove the white sheets so we can do the real work.
3. Now remove any loose plastic lenses (probably all of them).
4. Place glue on the three feet of each lens.
5. Insert each lens back into its location.
6. Allow time for the glue to cure. (In some cases, it may take several hours.)
The Last Step, 8: Put Everything Back Together
1. Ensure all plastic lenses are firmly in place and the glue has cured.
2. Put everything back together in the opposite order that you took it apart.
Now set up the TV as it was and power it up. The white spots should be gone.
The whole process may take some time, so try this method when you have plenty of free time. A similar method will be used for a laptop screen as well.
Method 2: Apply This If You Have a Black Spot on Your LCD Screen
Black-colored spots appeared on the screen because some pixels on the screen are dead and, consequently they cannot show color. It is not possible to repair these spots but you can move them to one side of the screen.
To do so, grab a soft cloth or rubber and apply pressure to the black spot. If it moves, keep rubbing until it is where you would like it to be.
Once you’ve placed them aside, cover them with white paper to prevent further damage. Doing so will help your eyes stay healthy and allow you to continue working on the screen.
If your black spots appear in a circular shape, then you would need to cut out a circle that is the same diameter as the spot. Then place the paper on top of it and stick it down with transparent adhesive.
Hopefully, you will be able to follow, and this method will let you bring your black spot where you need it.
Check To See If Your Screen Has a Warranty
If you find any kind of fault with your device, such as a cracked LCD panel, first make sure that the device’s warranty hasn’t run out yet. If it has, then call your device maker and ask them about getting it fixed.
You may also be able to get it repaired through an authorized service provider. However, if the device is no longer covered by warranty, then you’ll have to pay for repairs.
Dead Pixels Can Be Increased, so Don’t Overdo It If There is A Black Spot
If your display has an uneven pressure area and the dead pixels are white, do not try to eliminate them by rubbing them too hard. If you overdo it, the white areas will spread, and your screen will be totally ruined.
Instead, you gradually rub it and try to push the problem area into a corner. When it is there, do nothing again. Change the LCD if the situation becomes unbearable.
It Is Good to Call Your Expert Friend
It might be helpful to ask someone who knows more about technology for advice. After all, if something goes wrong, it could get worse. So, feel comfortable asking a buddy who is passionate about technology.
If that’s not an option, then you should consider visiting a store or contacting an electrician who has dealt with similar issues before.

A. No, applying too much pressure can cause permanent damage to your device. You should only lightly rub the screen with a soft, lint-free material. Do not press down hard on the screen or scratch it with any object.
Q 3. What is the best way to fix a stuck pixel on an LCD screen?
A. There is nothing wrong with your screen. Sometimes, these issues occur due to internal damage to the display itself. In such cases, it is advisable to take your laptop to an authorized service center where technicians can diagnose the issue and repair it. However, if you notice any signs of discoloration or fading, then you should immediately contact a professional technician who can help you resolve the issue.
