What should I do if the old TV is illegible?

The blurred handwriting of the old TV set is mainly due to the long-term use of the old TV set, which will lead to some problems such as aging and damage of some components inside the TV set due to the influence of external factors such as dust and moisture, thus leading to blurred images or handwriting. Here are several solutions.

1. Cleaning the TV: First, try to clean the dust around and on the back of the TV screen with a clean cloth or paper towel.

2. Replace the TV base: Some small parts on the TV base have been excessively worn, which may lead to blurred images. At this time, it is necessary to replace the TV base.

3. Adjust TV parameters: Adjusting the brightness, contrast and color of the TV may make the TV display clearer.

4. Replace the TV picture tube: If the above methods fail, you may need to replace the TV picture tube. You can take the TV apart and find a professional repairman or repair shop to repair it.

In a word, the problem of unclear old TV can be solved by the above methods. When using, it is best to keep the TV clean, avoid excessive damage to the TV for a long time, and maintain the TV regularly to ensure the clear and stable display effect of the TV.
