What should I do if my TV becomes red?

The red screen of the TV can generally be judged as a color cast, and the causes and solutions are:

1. The failure of the internal degaussing circuit of the TV causes the color deviation of the TV, which can generally be solved by replacing the degausser;

2、Some TVs have a color temperature setting function,If there is an error in the setting, it will also cause a color shift failure,But the actual performance of this color cast is that the whole screen is biased towards a background color; This fault can be solved by simply re-adjusting the color temperature parameters correctly;

3. TVs generally rely on electron beams to scan the corresponding phosphors on the screen to produce ever-changing colors; When the opto-amplification circuit of other colors is faulty (such as the opto-amp transistor is damaged), there will be a full-red color shift on the screen, and the opto-amp transistor needs to be replaced to solve the problem;

4. The picture tube of the TV will also cause color casting, which is generally manifested as lack of color, defocus, the screen is too bright or too dark, and there is a scan line; At this time, it is necessary to replace the picture tube;

Generally, you should open the back cover and look at the small circuit board at the tail of the picture tube, which should have several adjustable resistors, and see if the one with g written in it is not in good contact, and you should consider replacing it. There are also related transistors. If it doesn't work, you have to replace the **ic.

Repairs are not so simple...

If your TV color stool turns red or violently red, it may be due to a variety of factors. Here are some of the reasons why a rough state can cause your TV to turn red and how to deal with it.

1.Problems with color settings.

If your TV's tonal settings aren't adjusted correctly, the TV may appear reddish. This kind of problem is easy to solve. Just find the "Tone Setting" option in the menu of your TV and adjust the color balance to ensure that the three colors of red, blue and green are balanced.

2.Problems with TV cables.

If the plug of your TV cable is damaged or not plugged in properly, the picture of your TV will be distorted. Check whether the plug of the cable is in good condition and plug it tightly, and replace the cable in time if it is damaged.

3.TV dust problem.

If the inside of the TV is filled with dust, it can also cause the color of the picture to be distorted. Regularly clean the inside of the TV from dust, especially on the back of the TV and around the vents.

4.Aging of electronic components in televisions.

If the aging parts of the TV cause the picture to be reddish, the only way to fix it is to repair or replace the TV. It is recommended that you go to a professional M&E repair service provider for repairs.
