Don’t be alarmed if your screen displays some strange dots and lines. It’s a simple problem to solve.

Repairing pressure-damaged TV screens is a time-consuming technique that necessitates considerable technical understanding.

It’s best to have someone who knows about LCDs guide you if you’re doing it for the first time.

Causes of Pressure Damage on TVs

Let’s discuss what causes LCD TV screen pressure damage before we fix it.

Physical damage, such as falling off, a sharp object striking the screen, or liquid droplets on the display screen, are common causes of pressure damage.

1. Pressed Crystal

Pressure damage, particularly pressure spots, is caused by pressed crystals inside the glass layer. It degrades picture quality and causes problems with viewing, such as flickering.

2. Contact with Other Objects

If you or someone slammed your TV screen against something, the resulting high pressure could damage the screen; this can happen when you relocate and cram your TV with other items.

3. The Screen has Fallen Over

If your TV isn’t mounted on the wall, it will likely fall over, causing pressure damage.

It’s essential to invest in a high-quality wall mount to avoid damaging your flat screen, rather than relying on a TV stand. It will save you a lot of money on repair costs. If your aesthetics allows for only TV stands, you should get an anti-tip TV strap.

4. Outdated Drivers

If vertical lines appear due to pressure damage, the issue is with the hardware. The TV will not work unless the drivers are up to date.

The Bad News:

Not all pressure damages can be easily fixed, and modern TVs are so delicate that pressure damages could render them completely useless. If these fixes don’t work for you, you’d have to decide between calling a technician or buying a new TV.

Note: If you have an active warranty, invoke it. DON’T take your TV apart if you have a warranty; it will void the warranty.

• Remove the smaller screws first, followed by the screws on the edge.

• After removing all the screws, slowly lift the lid back from the bottom.

• Place a finger between the lid and the TV once lifted.

• To remove, wiggle a little, and raise simultaneously.

3. Remove the Speaker Connections

Remove any connected cords to the speaker jack. Remove the wires one by one from both sides. Check if the PCBs are secured using screws (Printed Circuit Boards).

• Look for screws towards the bottom of the TV.

• Disconnect the cables from the PCB’s upper side.

• Disconnect the cables and remove the screws that hold the source PCBs in place.

The main phase begins when you remove the panel sheets.

• Collect the LED backlights’ little, circular reflectors.

• Using a soft cloth, clean the panel sheets.

• Assign them to their proper locations.

• Secure them with adhesive.

If the spot persists, try applying toothpaste to a cotton ball. To cover the area faster, run in a circular motion.

6. Reinstall the Display and the Rest of the TV

Finally, reassemble the TV screen by following the steps in reverse order. Follow each step one at a time, and give yourself enough time to complete the process.

• Place the panel sheets on the screen and close it.

• Close the case and screw the outer bracket in place.

• Connect the speaker connectors with cables.

We recommend removing the panel and wiping it with toothpaste if you still observe pressure spots after inspection.

It might take some effort, but if you can fix it, you’ll save a lot of money on repairs.
