Why is my Vizio TV blinking and flickering?

 There are many reasons for TV to flicker. Below are the common ones:

It is an error of the system of computer software that makes it produce a wrong result, or to work oddly.

2. HDMI Issues

HDMI cables are a special device with which a digital audio and image signal is transmitted from one multimedia device to another, while the quality remains at a high level during transmission and is not affected by electromagnetic interference.

The HDMI cable looks like a long cord, with connectors at both ends. One of these connectors has a rectangular or trapezoidal flat design.

Inspect cable box. HDMI cable can be the reason for the TV to flicker. In this case you will don’t have to make a factory reset.

3. T-Con

The T-CON chip provides clear capture and conversion of incoming data from the video controller, as well as efficient distribution of them across column and row systems.

The features of such a chip are: 6-bit system interface; maintaining the resolution of the XGA standard; the presence of an input for connecting a phase-locked frequency control system; resistance to possible electromagnetic interference.

Some dirt on the T-Con cable can be blocking the signal, or it can be a failure on the T-Con board.

4. Failure of the Backlight

All Vizio TVs have LCD panels. LCDs care for the colors and visuals on the screen.

Broken LED panels in the backlight, or a bad contact between LED strips (it’s, again, factory reset), or burst ambient light sensor can be the reason for blinking in one certain spot on the screen. Right before a burnout it shows some warning signs, such as flashing and dimming.
