Why Does My Vizio TV Turn On by Itself – Detailed Manual

First, look to see if the cable is connected properly and if it’s loose. In most cases, many people find slack in their cable box connections. Look to see if the correct connector is chosen and if the cable leads to the outlet.

To definitively verify that it works, disconnect the cable. Then reconnect it to both the TV and the outlet, pressing firmly. Then turn on the TV and watch it work for a certain amount of time.

If your Vizio TV fails all the time, check all the buttons. Maybe one of them is jammed or stuck. Don’t try to fix it yourself, just get a new Vizio remote. Here is how to turn on vizio tv without remote. If there is nothing wrong with the remote control, continue looking for the cause of the malfunction.

We already mentioned this mode in Vizio Smart TV above. Among other things, this feature allows you to remotely control the Vizio TV to other connected devices in your home. Other devices can interfere with the Vizio TV when it is switched on. Because of this, it will periodically turn on and off.

Of course, removing all devices is difficult enough. However, you can fix this problem very easily. It is enough to disable the CEC mode on Vizio Smart TV. To do this, you will need the following steps:

1. First, take the remote control in your hand and press Menu.
2. Then open Settings.
3. Then go to System, find the CEC section.
4. Click on Disable.
5. Check to see if the problem has been fixed.

As we have already found out, Vizio TV’s independent behavior is due to something interfering with the signal. And the signal can also be disrupted by other devices in the same network as the TV. So the Vizio TV will turn on and off whenever it wants.

If there are several other home devices in the shared network, simply turn on ECO mode on the Vizio Smart TV. The procedure is very simple and requires only a few steps:

1. Open Settings.
2. Find System and click on Power Mode.
3. Find ECO Mode in Power Mode and turn it on.
4. Check to see if this solved the problem.

Remember that ECO Mode also blocks you from streaming all content from other devices.

If the ECO mode does not help you to fix the problem. We recommend turning on Quick Start Mode. To change this, go to Settings > System > Power Mode > Quick Start Mode. Now see if the error remains.

The Vizio TV can also turn on if the sleep timer is set. Vizio TV turns off at a certain time because of the timer. All Vizio TVs have a built-in auto power-off function. When the timer goes off, the TV turns off. It also works the other way around.

To avoid this problem, you need to turn off the auto power off and increase the time after which the TV goes to sleep. If you don’t do this, it can periodically turn off even after a short period of inactivity. This is the most common problem among users, which is quite easy to deal with.

If the TV does not respond to the remote control, and the red LED is constantly blinking, it means that the power adapter is out of order. This failure can also cause the TV to turn on by itself. The power adapter is considered one of the most vulnerable parts of modern TVs working on the Smart TV platform.

The power supply fails as a result of regular power surges. Even a faulty outlet can provoke a failure of this hardware module. Before replacing the part, you need to perform a diagnosis. Remove the back cover of the TV. If the component is burned out, there will be soot on the power supply.

You can replace the faulty hardware module yourself. However, only if you have the appropriate skills. You need to have a good understanding of electronics and know the basic laws of physics. If you do not have the equipment and knowledge, then you should not expose the technique to the threat of exacerbating the breakdown.

Contact Vizio support. Engineers are able to quickly install the original power supply.
If you have replaced the power supply yourself, the TV works, but still turns on arbitrarily, then you need to call an electrician. A specialist should measure the voltage of the outlet, and then adjust the power supply.

Dust and moisture deposited on the surface of the microcircuits may cause short circuits resulting in burnout of the basic hardware modules. Therefore, it is necessary to adhere to the rules of care to maximize the service life of the equipment.

For example, moisture gets in because many users spray cleaning products on the screen. This should not be done. Spray the liquid on a dry cloth or microfiber, and then wipe the screen.

Absolutely all devices need to be cleaned regularly from dust. Televisions are no exception to this rule. It is not impossible that the TV turns off and on randomly because of dust accumulated on the microcircuits. Dust accumulation conducts current.

Therefore, they are a catalyst for the occurrence of sparks. As a result, a short circuit occurs. To clean the equipment from dust, remove the back cover, and then gently blow out the dust with a vacuum cleaner.
