What Causes a TV Screen to Blink Different Colors?

Several factors can lead to a TV screen blinking different colors. Below are some common causes and their potential solutions:

Sometimes, incorrect display settings can cause color issues on your TV screen. This might include settings related to color balance, contrast, or picture mode.
