It can be frustrating when the colour on an LCD television seems to change for no reason. There are a number of items that can be checked to see whether the issue is a simple fix or whether the television will need further repair. Check these items before contacting a television repair company to fix your television.

Skill level:
Moderately Easy


  1. 1

    Check the settings on the television. This can be done through the remote control by pressing the "Settings" button. Play with the settings for colour, brightness and contrast. If changing these settings do not make a significant change to the quality of the colour, return the settings back to the levels at the beginning.

  2. 2

    Check all cables coming into the television and system. Unplug and reinsert all cords leading into the television. Check all cables leading from the cable/converter box. Unplug and reinsert each cable. To check the cable wire leading from the wall shake or move the cable to see whether the colour on the television changes. If any of the cables make a change in the colour, they might need to be replaced.

  3. 3

    Reset the cable box. Cable boxes will periodically need updating. If your box has not updated correctly, it might cause issues, such as colours being altered. To see whether your system has the most recent update, unplug the cable box. Allow the box to sit for a moment and replug the system. A reset will take a few moments.

  4. 4

    Reset your television set. While the television is not updated like a cable box, it is possible for the system to get a malfunction and display the wrong colours. Unplug the television from the power source. Some televisions might require being unplugged for up to two hours to allow the systems to reset. Look at your User's Manual for instructions on resetting your television.
