If you’re someone who is an avid TV user then you may have come across a problem where you see tiny blue dots on your TV screen which may have had you in confusion as to what caused them in the first place and how you can get rid of them to get back to watching TV on a flawless screen.
Don’t be concerned if you detect blue spots or dots on your television. This issue is known to occur on the majority of LCD TVs and is really simple to resolve. The blue specks (dots) you see are the light from your TV’s LED backlight.
Some pieces within the TV may migrate from their original location as a result of repeated use or poor quality, causing blue spots or dots to appear on the screen.
The Problem:
What you may be seeing is one or more of the more than 2,000,000 dots that make up the LCD or OLED screen’s composition. These dots (sometimes referred to as pixels) might be red, green, blue, white, or black.
To maintain a high quality of operation, these LCD/OLED screens are manufactured using high-precision technology. However, regardless of the manufacturer, there may be a tiny number of dots that do not change color on all LCD/OLED panels. This is a common phenomenon with all LCD/OLED screens from all manufacturers, and it is inherent in the technology. Most of the time, these dots remain on the screen but are only visible when an all-white or all-black image is displayed and should not be seen under normal viewing conditions.
Blue Spots on the Screen:
If your TV screen has blue spots, it might be due to a manufacturing flaw in the blue LED backlight. In this situation, you will need to change your backlight.
To return to the standard image mode, you may change the color adjustments, backlight, and hue from those settings.
You may repair a blue screen on a TV screen by following these steps:
Navigate to your TV’s settings and, using the Up/Down arrows, access the Picture and Display window.
Click on photo modifications using the same Up/Down buttons.
There, you’ll discover a list of options that you may tweak individually to restore the original colors.
The Reset option returns all modifications to their original state or factory defaults.
You may change the brightness of the screen by adjusting the backlight.
You may improve clarity by adjusting the contrast panel.
By changing the intensity of the color, you can adjust the depth of the colors.
If your TV has a Hue setting, you may vary the blue, red, and green tones.
You may modify the whiteness of the screen by adjusting the color temperature.
Cool color temperature produces a blue tint, neutral temperature produces a neutral tint, and heated temperature produces a red tint.
Sometimes the blue spots may appear in a purple tone too and these purple-colored spots are created by the HDMI cable connection from the cable box. These purplish-blue hue spots can be removed by doing the following steps:
Check that the HDMI wires are securely hooked into or linked to your TV.
Wait for 10 to 15 seconds after disconnecting the power cord from the main connection or the wall. Reattach the power cord.
If the problem persists, the HDMI cable may be defective. You can try a different HDMI cable or contact a specialist for assistance.
How To Fix These Blue Dots:
Whether or not you have previous experience repairing TVs or electronics, I believe you will be able to fix your TV and remove the blue spots on your TV screen if you follow the directions below. You’ll need to unscrew your LCD TV and use glue to reattach the fallen reflectors back into position. All you need to do is just follow the following steps and you’ll be able to fix this problem without the need for help from a technician.
Turn off your television and unplug it from the power supply.
Remove all of the screws that keep your TV’s back panel in place.
Pull out the metal tabs with caution. (Be cautious) Disconnect the speaker connectors and take the speakers away from your TV.
Lift the metal plate and disconnect the circuit board stuff from it.
Lift the tabs on the plastic frame with care and search for the fallen reflectors.
To add adhesive to the Q-tips, use them. (Apply glue around the area where the reflector has fallen) After applying adhesive, set the reflector in position and hold it in place until it is squeezed.
After you’ve finished, reverse the process to assemble your TV.
The issue of blue spots or dots is not new, and it can show on practically any LCD or LED TV, whether brand new or secondhand. We have previously stated in this post that this problem is simply fixed and that you do not need to be concerned.
Keep in mind that if your TV is still under warranty, you should call a service facility and let them resolve the situation. They have greater knowledge of these kinds of issues and will repair your TV for free.
You can unscrew the TV to examine whether the reflecting lenses have come loose, and then use super glue to reattach them. If you believe you won’t be able to solve the problem on your own, contact a TV service specialist and delegate the task to him. I hope we were able to assist you in some way and that you were able to fix the problem with blue dots.
