How To Fix Vizio TV Restarting Continuously?

Inspect The Power Cable

A power cable is often the culprit behind many problems like Vizio TV not turning on or the TV turning on and off by itself.

A faulty power cable can be one of the main reasons why your Vizio TV is restarting constantly.

The first thing you need to do is to unplug your Vizio TV and plug it back.

Inspect the power cable and see if the cable is damaged. If you find any cracks or bends in the cable, it might not be able to send power to the TV properly.

If the TV power cable is broken, you will have to replace it with a new one. Since most TVs’ power cable is not detachable, you’ll have to take them to the nearest service center or ask a technician to fix them.

Switch The Power Outlet

If the problem persists, it would be better to connect your Vizio TV to a different power outlet.

If you spot the power LED light on the TV blinks continuously, it is a problem related to the power supply. It can be either with the power source to which the TV is connected or the power unit on the motherboard.

If the TV does not restart after switching the power outlet, the issue was with the power outlet to which you connected the TV earlier.

Power Cycle Vizio TV

Power cycling Vizio TV will help you eliminate several problems like Vizio TV stuck on logo or the blue tint issue.

It is a simple process in which you drain the residual power left in the TV or the piled-up static charges.
