Stains, discoloration and other defects of screens on phones, laptops and monitors happen quite often. First of all, it is worth checking the settings and software. If this does not help, you will most likely need hardware repair or replacement of the component.

To minimize the risk of damage it is worth taking care of the devices protect them from dust, extreme temperatures and mechanical damage. Make regular backups of your data in case repairs are needed.

If none of the above methods work, you will most likely need to replace the display itself or the device’s motherboard. For phones, it often pays to replace the entire device.

Black spots on industrial screens most often indicate physical damage to the matrix – these can be cracks, dents or manufacturing defects in the LCD panel itself. In devices that are exposed to vibrations or mechanical impacts (e.g., in machinery), microcracks can occur in the display structure and after some time a black spot appears in the corner of the screen, for example.

A black spot is worth distinguishing from a dead pixel, which is always shaped like a single dot. The stain, in turn, can be irregular in shape and vary in size.

The black spot on the monitor can vary in shape and size depending on the extent of the damage. Stains on the phone’s display sometimes appear gradually and increase in size over time. To check whether the cause is a physical damage to the panel rather than an electronic malfunction, it is worth connecting the screen to the power supply, but without the video signal. If the stains are still visible, this confirms the thesis that the matrix is damaged.

If the stain appeared suddenly, check the display cable in the first place. Loosening of the connector may cause partial disappearance of the image. Check the connections on both sides of the cable and reconnect.

Unexpected yellow spot on the display of an industrial device can have several causes. First of all, you need to check the color display settings – sometimes gamma, contrast, color temperature parameters are changed by accident. If restoring the default values did not help, check the signal cable and connections.

A black spot on the phone’s screen may indicate a faulty pixel or group of pixels in the display. Both the LEDs themselves and the circuits that control the backlighting of the matrix can be damaged. Other possible causes include:

If the stain is permanent and does not disappear after restarting the device, the cause may be more serious. Try connecting the screen to another device, such as a computer. If the stain is still visible, the culprit is most likely the LCD panel itself.

Colored stripes running across the screen indicate a more serious hardware failure. Most often, they occur as a result of overheating of the display’s components – the circuits that control or power the matrix. Constant overheating can lead to permanent damage.

Loose pins in the connector can cause interference and errors in the transmission of some components of the RGB signal. It is also a good idea to make sure that the electrical system at the site of the device is stable and there are no voltage spikes. If this does not help, the matrix or the display motherboard may have been damaged.
