When your Vizio TV isn’t turning on because of the residual electrical charge stored by its capacitors during use, it makes sense to address the issue by draining them. Draining a device’s residual electrical charge is called power cycling.

You can power cycle your Vizio TV by disconnecting it from its power source. Over time, the residual electrical charges in the Vizio TV’s capacitors should dissipate, but you can speed this up by pressing and holding the power button on its back panel.

This action can fix Vizio TV errors such as sluggish startup, black screen issues, misbehaving apps, sound problems, bootup errors, etc. As such, it’s a solution we recommend you try whenever your Vizio TV isn’t turning on.

Step 1: Turn off your Vizio TV and unplug the power cable.

Note: Unplugging the power cable on a turned-on Vizio TV will force it to turn off.
Step 2: Hold the physical power button at the back of the TV for 60 seconds to eliminate its residual electrical charges.

Note: You can achieve the same result by keeping the Vizio TV unplugged for much longer without holding down the power button.
Step 3: Plug in your Vizio TV’s power cable.

Step 4: Click the power button to turn on your Vizio TV.

FIX 2. Check for updates

Since a software update requires an active device to complete the download and installation, you can’t use this action if your Vizio smart TV doesn’t turn on. However, that shouldn’t stop you from updating your Vizio TV if it still turns on occasionally.

Doing so will help reduce the likelihood of your Vizio TV suffering from a bootup issue in the future. Bootup errors preventing your Vizio from turning on might occur due to software-related errors and bugs.

Step 1: Press the Vizio remote’s Menu button to access the settings menu.

Step 2: Go to System.

Step 3: Click Check for Updates and select Yes to confirm your selection.

Note: Your Vizio TV should search for an available update if it’s connected to the Internet.
Step 4: Click Yes to authorize downloading and installing the latest software update.
Note: Free up some space on your Vizio TV if its storage memory runs low.

FIX 3. Inspect the HDMI connection

When your Vizio TV isn’t turning on, there might be a problem with your HDMI connection. In such cases, your device is running but it appears to be off due to a video signal transmission failure from the input device.

When this happens, the display screen of your Vizio TV stays black even when plugged into a power source. The only way to fix this issue is to correct the HDMI connection of your TV and the external input device by checking for loose cables.

You must also clean the HDMI ports since foreign particles, like dirt and dust, can block the video signal transmission. It’s why the display screen might stay black even when you turn on your Vizio TV and plug in its HDMI cable correctly.

Step 1: Check the HDMI cable connected to the back of the Vizio TV and its external input device.

Note: Disconnect and reconnect the HDMI cable on both devices until it’s tight and secure.
Step 2: Inspect the HDMI cable for indication of broken contact pins or wear and tear on its wire.

Note: Switch to another HDMI cable if the one you’re using has damage.
Step 3: Check the HDMI ports for dirt or dust buildup and clean them using a can of compressed air.

Note: Before plugging in the cable, you should clean the HDMI ports on the Vizio TV and the external input device.
Step 4: Using a contact cleaner spray, clean any rust buildup on the HDMI ports.

Note: Never apply contact cleaner on a turned-on Vizio TV to avoid circuit damage.
Step 5: Clean the rust using a soft brush or cloth and remove any contact cleaner residue.

FIX 4. Reconnect the power cable at the back of the TV

Since televisions rely on wall outlets’ electricity, you must ensure your Vizio TV’s power cable is always secure. This way, it can share enough power with its components and ensure everything works as intended and without issues.

Otherwise, it will not turn on if the electricity from the wall outlet is insufficient. To avoid such problems, we recommend unplugging and replugging the power cable before every use.

Doing this method is an excellent way to ensure your Vizio TV has no power supply issue due to a loose power cable. If securing the connection doesn’t fix the issue, you can also try switching to another power cable to see if the problem was due to a faulty cable.

Step 1: Press the Vizio remote’s power button to turn off your TV.

Note: Pressing the Vizio TV’s power button on its back panel will achieve a similar result.
Step 2: Unplug one end of the power cable that plugs into your Vizio TV’s DC/IN port.

Step 3: Plug the power cable back into the Vizio TV’s DC/IN port and try turning the device on.
Note: The power cable must be tight and secure.

FIX 5. Factory reset it

The idea behind a factory reset is similar to updating the TV’s system software. The only difference is you remove your data and files to restore its initial state instead of upgrading the existing system software to an improved version.

Unfortunately, you can’t use the standard reset method if your Vizio smart TV doesn’t turn on since you need to navigate its system menu. Therefore, you must do a  factory reset by using its built-in physical buttons to bypass this limitation.

This method allows you to initiate the factory reset process on your Vizio TV without access to its settings menu. However, it means that its physical button must work to execute this solution without any issues.

Step 1: Hold your Vizio TV’s volume down and input buttons simultaneously for 10 seconds.

Note: Other Vizio TV models only need you to hold the input button to start the reset.
Step 2: Wait as the Vizio TV clears its system memory and restores its default settings.

FIX 6. Run tests on your power supply

As mentioned, sufficient electricity is crucial for your TV to turn on without issues. As such, we suggest running tests on your power supply to ensure they provide your Vizio TV and its components enough power to run as intended.

Otherwise, the insufficient power supply might explain why your Vizio smart TV won’t turn on. You can test the power outlets in your house using a voltmeter or multimeter to determine if they provide the recommended voltage to power your television.

To safely plug in your Vizio TV, the reading on your 120V power outlets should appear between 110 and 120 volts in the multimeter. A lower or higher reading indicates your power supply is faulty and needs immediate repair.

FIX 6. Run tests on your power supply 

You can contact an electrician to fix the electrical outlets in your house if you can’t do it yourself. It’s better to have an expert look at your power outlets to protect yourself from electrical accidents, which might cause further damage.

FIX 7. Inspect the board for blown fuses and loose wires

If your Vizio TV won’t turn on and its power light fades off, it could be a sign of hardware damage. This problem happens when your Vizio TV has some blown fuses or loose wires in its T-con, main, and power supply boards.

Since these components are internal, you need to open the TV’s back panel to do the inspection. Once you’ve confirmed the hardware issue, you can perform the replacement or send your Vizio TV to a service center and have a technician do it.

The repair costs will depend on the extent of damage to your Vizio TV. If the repair costs are too high, it might be better to get a new TV instead.

Step 1: Turn off your Vizio TV and place it face down on a smooth, flat surface.

Step 2: Unscrew your Vizio TV’s back cover.

Step 3: Remove the back cover to expose the components inside your Vizio TV.

Step 4: Check the T-con board, main board, power supply board, and all connected cables.

Step 5: Reconnect the loose wires and replace the blown fuses in each board.
Note: Take a photo of your Vizio TV before removing any components, so you know how to assemble everything.

FIX 8. Check Vizio TV warranty
