How to fix Pressure Spots on LCD Screen
See below guide step by step.
What are the Common Problems with LCD display?
You may have observed the sudden flashing or flickering of your LCD screen usually after it is turned on. The main reason behind it is the loose video cable. In most cases, it is loose from the connection of monitor so if you tighten it there, the display will become stable. The cable can be faulty so you would need to get a new one in that case. Another reason behind the flickering is incorrect refresh rate settings. Most monitors work with 60 Hz refresh rate. The newer models that are specially designed for gaming purposes have higher refresh rates as well. Therefore, you need to see the recommended refresh rate of your display and set it accordingly from the settings.
- Vertical Lines
Users have reported vertical lines on their screens which can be of any colour. The most common issue is with the LCD display. You can find this by applying some pressure on the affected area and see if the lines change in any way. If so, your LCD is damaged and it would need replacement. Therefore, the problem lies with the hardware. However, you may check the display settings from the control panel to check if everything is set at the recommended level. Always keep your display drivers updated and check that the graphics card is working properly as well.
- Dead pixels
This issue is also faced by a lot of people in which a black dot starts appearing on the screen permanently. It occurs because the pixel behind that part of the screen does not illuminate. Users often ask, what is the best way to fix a stuck pixel on an LCD screen? Although it does not affect your monitor or overall working in any way, there are still some softwares which can help in fixing dead or stuck pixels. The programs force the area of the affected pixel to change colours rapidly which can solve the problem. You may need to repeat this process for few hours before any change is visible.
Some users have also reported that by applying pressure on the stuck pixel, it started to work again after repeated attempts. However, there is a risk in this procedure because you may damage the screen unknowingly which will put a large bill in your pocket. The best way to deal with dead pixels is to wait and keep using the device unless it does not spread more to the screen.
- Cracks and Spots
If you see a crack or blotch on screen which is significantly different than other colours on the display, it means that the LCD has gone through some physical damage. It can result due to the monitor falling off, liquid splashes on screen, sharp item hitting the screen or any similar event. Unfortunately, this means that you would need to replace the display because it is not possible to repair such damages. The internal components of the screen get damaged which are mostly not repairable.
- Buzzing Sounds
Have you heard a slight buzz while you are working on your computer? It is most probably caused by a problem in the backlights of the display. The older monitors used fluorescent lighting tubes which are known to malfunction easily. The LED monitors have become much better in their efficiency and reliability but the power fluctuations can cause sounds in them as well. Try to keep a voltage regulator with the computer if there are frequent disruptions in power.
- Incorrect Resolution
Have you experienced a change in screen’s resolution or brightness? The major reason behind it is the graphics card. There may be issue in the graphics driver which can be resolved by a software update or re installation. If the problem is still there, then you would need to get a new graphics card for your device. Sometimes, you may need to change the port if other components are working fine. Your battery may have some issue in charging because the displays often adjust themselves while charging and discharging. In such a case, you would need to replace the battery or charger.
- Frequent Shutoffs
This is another common issue faced by a lot of users. The display shut offs randomly. Experts believe that power fluctuations may be a major reason behind this. You need to check the main power supply of your house and see that the circuit breaker does not trip frequently. If so, the issue is with the main electricity. Another cause of the screen shutting down is the overheating of the device. The processor may overheat due to faulty fan or other reasons which you would need to sort out. You can check this easily by touching the laptop or PC’s casing after it turns off. If it feels very hot, the internal components are overheating and the display shuts off automatically to prevent it from further damage.

Removing Palm Pressure Mark from LCD
Have you ever seen a slight change in the display from a particular area which is only noticeable once you look for it? I experienced a similar issue when I bought my Samsung LCD TV. Although the marks were barely visible, I still wanted to get rid of them because I did not like it when I was watching content on screen. After some research, I got to know about some essential details regarding it.
The marks are mostly caused during the packing/unpacking process of the TVs. In order to prevent them, people should always hold the screens from top to bottom in which they wrap their hands around the panel. Keep your fingers to the back side and do not let much pressure on the display itself. Use suction cups on the areas where the marks are present. This will remove them in majority of cases but if it they still remain, then you would have to replace the screen. Mostly, such pressure marks are negligible so you may keep using the device as it is.
