How to fix blurred fonts on old TV sets

Older televisions used shaded tubes for their displays, a display that has been phased out on modern TVs and replaced with LCD panels. However, if you're still using an old-fashioned TV today, you may be experiencing blurry pictures.

First, you need to consider whether you need to adjust the resolution of your TV. Older TVs have a much lower resolution than modern TVs, so images may appear blurry. If you're streaming content to your TV through an external device, such as a DVD player or game console, you'll need to set the device's resolution to match that of your TV to ensure the best image quality.

In addition, older televisions use picture tubes, whose longevity and use over time can lead to the inevitable aging of the tubes, which can also lead to blurred picture quality. Therefore, if your TV has been in use for many years, there is a high probability that the cause of the blurring is the picture tube. In this case, you can only replace the picture tube or the entire TV set to get a clear picture again.

Also, check that your connecting wires are in good condition, if you are using old wires there are chances that they may break or lose their connectivity, which can also lead to distorted or blurred images.

In short, fixing the blurriness of an old TV is not easy, but adjusting the resolution, checking the wiring, and replacing the picture tube are all ways to fix the problem. However, choose these methods carefully as they could potentially cost more than buying a new modern TV set. Therefore, it is best to transition to a modern TV set early for a better viewing experience.
