What are the seven red, yellow, blue and green bars on TCL TV?

There are several possibilities to display seven stripes of red, yellow, blue and green on the TV screen. The most common is that the TV display screen is broken, the image recognition is faulty, the color baseband is chaotic, and the image cannot be displayed normally. The price of the display screen accounts for more than half of the whole TV set. Most people buy new TV sets without repairing them. Another possibility is that the degaussing circuit of the TV set has failed, and the TV set cannot be degaussed, or there is a magnetic field around the TV set that affects the degaussing function of the TV set. Generally speaking, if the TV set is replaced by the other party, if the stripes cannot disappear, it means that the degaussing function of the TV set has failed. This possibility is slightly less, because generally speaking, the color bars that appear when the degaussing circuit fails should be irregular. Moreover, the color spots displayed in the four corners of the TV set are abnormal, and the seven stripes of this TV set are regular, and there are no color spots around the TV set, so the possibility of degaussing circuit failure is very small, and the display screen is most likely broken, so I suggest you not to repair it again. Nowadays, the TV set is not expensive and has many functions. You should buy a new TV set quickly.
