Fixing Television Colour Problems: TV Repair in Nairobi
Television colour problems can ruin your viewing experience, whether you're watching your favorite show or catching up on the latest news. If the colours on your TV screen appear distorted, washed out, or completely gone, it’s time to seek professional help. Fortunately, there are reliable services for TV Repair in Nairobi that specialize in fixing colour issues on all types of TVs, including LED, LCD, OLED, and plasma models.
In this article, we will look at the common causes of TV colour problems, how they are diagnosed, and the repair solutions offered by TV repair technicians in Nairobi.
Common TV Colour Problems
-
Discoloured or Faded Screen One of the most common issues is a screen that appears faded, yellowish, or discoloured. This can happen due to incorrect display settings, a loose or faulty HDMI cable, or a problem with the TV's colour control board. Sometimes, these issues can be resolved by adjusting the picture settings on your TV, but if the problem persists, professional repair is necessary.
-
Red, Green, or Blue Tints TVs can develop problems where the screen has a strong tint of red, green, or blue. This colour distortion can be caused by a malfunctioning colour wheel or a defect in the internal circuitry responsible for balancing the RGB (Red, Green, Blue) signals. It is important to have this issue addressed quickly, as leaving it unchecked can lead to more serious damage.
-
No Colour (Black and White Display) If your TV suddenly displays in black and white, there might be a problem with the TV’s colour settings or the video source. However, if adjusting these settings doesn’t fix the problem, it could indicate an issue with the colour processing system in the TV. A professional TV repair service in Nairobi will be able to identify and resolve this issue.
-
Flashing or Flickering Colours Flickering colours or a rapidly changing hue can make it impossible to watch anything on the screen. This is usually a sign of a malfunctioning backlight, a loose cable, or an internal hardware issue. A qualified technician can diagnose the exact problem and replace faulty parts.
Diagnosis and Repair Procedures
For residents in Nairobi, professional TV Repair in Nairobi services offer comprehensive solutions for colour-related problems. Below are the typical steps involved in diagnosing and fixing TV colour issues:
1. Initial Diagnosis
When you contact a technician for TV repair, the first step is to run diagnostic tests. The technician checks your TV’s picture settings and connections, such as the HDMI or AV cables, to rule out simple causes. They will also test other input sources to determine whether the problem lies in the TV itself or in an external device like a gaming console or DVD player.
2. Checking the Backlight
If the colour issue involves flickering or a washed-out screen, the technician will inspect the backlight, which is responsible for illuminating the screen. If the backlight is faulty or uneven, it may need to be repaired or replaced.
3. Repairing the Colour Control Board
When the problem is related to a specific colour tint or complete loss of colour, the colour control board or T-Con board (timing control board) may be malfunctioning. This component manages the distribution of colours on the screen. The technician will either repair or replace the board, depending on the extent of the damage.
4. Replacing Faulty Cables or Connectors
Loose or damaged cables can lead to a distorted picture or no colour at all. The technician will inspect the internal connectors and cables and replace any that are damaged or worn out.
5. Calibrating the Screen
After making the necessary repairs, the technician will recalibrate the TV screen to ensure that the colours are balanced and the display is clear. This final step ensures that the problem is fully resolved and the TV is performing at its best.
