Troubleshooting Your CRT TV

If you still have a cathode-ray tube television, or CRT TV, chances are good that you have had it for a long time and it might not be working as well as it used to. Here are some tips for troubleshooting your CRT TV so that you can keep it going for several more years to come.

1. No Image On the Screen

If there is no image on your screen, then you are first going to need to check everything obvious before calling a television repair company. First, check the power cord to make sure that it is plugged in and able to get enough power from the outlet to your television so that your CRT TV can function properly. If power is going to your television, the next step is to check the picture settings. The most common culprit is brightness. If your brightness is turned down too low, then all you are going to be able to see is a black screen. First, see if you can increase the brightness manually. From there, also check the sharpness and contrast manually or by using the remote, depending on the type of CRT TV that you have. If all of these settings, when turned up to their highest level, do not produce an image with any level of clarity, then you are going to need to call in a repair professional to look at the video cable itself.

2. Images Are Not Lining Up Properly

If you turn on your television and see that the image is bowed around the edges or half of the image does not line up properly with the other half of the image, then you are going to need to go to the back of your television. Place your hand near the television but not on top of it. If you can feel heat, then there’s a good chance the internal temperature of the TV caused the convergence circuit to fail. You can call a television repair company and simply tell them that you need to get the convergence circuit replaced. This project does not take very long and should be able to be easily fixed while inside the home.

3. Horizontal or Vertical Line on the Image

Finally if you see one or more horizontal or vertical lines on your screen, then you have a yoke that has a burnt out coil. This simply needs to be replaced by a professional.
