How to Fix VIZIO/LG/Sony/Roku/Hisense/TCL TV Not Turn on Issue

Why Won’t My TV Turn on?

TV is one of the commonly used devices in the home. However, no matter what TV you use — VIZIO, LG, Sony, Roku, Hisense, or TCL — you may meet the “TV not turning on” issue sometimes.

Why won’t my VIZIO TV turn on? Many people will ask this question. However, for any TVs (VIZIO TV, LG TV, TCL TV, etc.), the causes of the TV not turning issue on are the same. The common reasons are as follows:

• TV remote control problem.
• Power cable connection issue.
• Outdated or corrupt firmware. This usually prevents the TV from turning on normally.
• Damaged internal components, especially the power supply board.

Then, how to solve the “TV not turning on” issue? You can refer to the following methods.

Method 1. Unplug the Power Cable and Re-plug It

When a TV won’t turn on, you should check the power light first. If it is not lighting up at all, it means that your TV is not connected to the power properly.

In this case, you should unplug the power cable from the back of the TV and the outlet. Wait around 30 seconds, and then re-plug the power cable into them. If necessary, you should check whether the outlet works well.

Method 2. Check the TV Remote Control

If the TV is connected to the power properly, try using the TV remote control to turn on the TV. If the TV won’t turn on, you can try to turn on the TV using the power switch on the unit, not the remote. If the TV turns on with the power button, it means that there is something wrong with the TV remote control. Possible reasons are as follows:

1. The view from the remote to TV is obstructed, making it difficult for the TV to receive signals. In this case, you need to remove barriers between the TV and the remote.
2. The battery in the TV remote control has been exhausted. In this case, you just need to replace the battery. This may require you to remove the bottom cover of the remote control.
3. Some components in the TV remote control are damaged. In this case, you may need to purchase a new remote control. If you don’t want to do that, you can download a TV remote app and use that to control your TV. Some TV models have this feature.

Method 3. Select the Correct Input Source

If you are using a cable box, you should select the correct input source. Otherwise, the TV won’t turn on normally. To select the correct input source, you can:

1. Turn on your TV.
2. Press the Source button on your remote control or press the MENU button on the side or bottom of the TV.
3. Select the desired input mode.

Method 4. Update the TV Firmware or Factory Reset the TV

If a TV won’t turn on normally, you can also try updating its firmware to solve the problem. If there is Internet on the TV, you can update the firmware via the Internet directly. However, as the TV won’t turn on normally, I recommend you update the TV firmware via a USB drive. Here is the guide:

Step 1: Prepare a USB drive and format it to FAT32 that is compatible with most TVs. As some USB drives are larger than 32GB and common tools can’t format USB drives over 32GB to FAT32, I recommend you use MiniTool Partition Wizard to format the drive.

1. Connect the USB drive to your PC.
2. Launch MiniTool Partition Wizard and go to its main interface.
3. Right-click the partition on the USB drive and choose Format from the context menu.
4. Set the File System to FAT32 or other proper file systems and then click OK on the pop-up window.
5. Click the Apply button to carry out the pending operation.

Step 2: Download the latest TV firmware file and extract it to the USB drive. Then, plug the USB drive into the TV and follow the on-screen instructions to update the TV. As for the detailed steps, you can refer to this post: Update Firmware and Apps on TV [LG, Sony, VIZIO, and Apple].

If this method doesn’t solve the problem, you can try factory resetting the TV. In this case, you can refer to this post: How to Reset a TV [Samsung, Roku, Apple, LG, VIZIO, and Philips].

Method 5. Contact the TV Maintenance Staff

The electronic units in TVs are susceptible to damage from storms or power outages. If all the above methods fail to solve the “TV not turning on” issue, there may be something wrong with your TV. In this case, you need to check the TV warranty. If the TV is still under the warranty, you can contact the TV manufacturers for free maintenance or replacement.

If the TV is not in the warranty, you can contact a nearby maintenance staff to repair your TV.

What Does the Power Light Color Indicate?

In general, when you turn on a TV, the power light will light on, indicating that the device is powering on. However, if the power light is not lighting up at all, it indicates a power issue.

If the power light flashes abnormally or displays abnormal colors, it means there is something wrong with your TV. When you troubleshoot a TV, learning the implication of the power light is very important.

#1. VIZIO TV Power Light

When you turn on a VIZIO TV, if the power indicator flashes from orange to white, wait about two minutes. If the power indicator light is still flashing, then there is a problem with your TV.

Some VIZIO TVs have a white LED power indicator light. When the TV powers on, the indicator light will fade out. If the light doesn’t fade off and just turns off, then there is a problem with your TV.

Some people report that they have encountered the “VIZIO TV won’t turn on but white light is on” or the “VIZIO TV won’t turn on power light fades off” issue. In most cases, they are encountering the same situation: the VIZIO TV won’t turn on, and the power light turns on and then shuts off.

In most cases, this “VIZIO TV not turning on” issue is caused by the damaged power supply board. Users should contact maintenance staff for replacement.
