Onn TV Won’t Turn ON – Troubleshoot And Diagnosis

Onn TV Won't Turn ON

Before we delve into the meat of our 8 quick fixes for an Onn TV that won’t turn on, let’s pause and try to comprehend the potential culprits behind this issue.

More often than not, issues with Onn TVs failing to power up can be traced back to abnormalities in the power supply, software glitches, or hardware malfunctions.

Observable symptoms might include a blank screen, a blinking red LED indicator, or unresponsive controls, all of which hint towards power-related problems.

When your Onn TV refuses to turn on, the first step towards troubleshooting involves identifying whether the issue originates from the power supply, the TV’s software, or its hardware components.

A simple power outage or surge could be responsible for your TV’s unresponsiveness. If the power supply checks out, it might be necessary to delve deeper into potential software glitches. While these are rarer, they can indeed render your Onn TV unresponsive, and we will detail methods to handle these later on.

Similarly, hardware malfunctions, although daunting, can be handled effectively and we will explore these as well. Our objective is to equip you with a wide array of solutions to ensure you can get back to enjoying your Onn TV without worry.

In the following sections, we will explore the quick fixes in detail, providing you a roadmap towards restoring your TV to its fully functional state. Each step is designed to be clear, actionable, and user-friendly, even for those who might not be technically inclined.

As we progress, remember to be patient and follow the instructions carefully for maximum success.

Quick Fix 1: Check Power Source

One of the most common causes behind a Onn TV not turning on lies in power-related issues. The power source is the lifeblood of your Onn TV, ensuring all components receive the necessary energy to function correctly. If there’s a disturbance in the power supply, your TV can behave abnormally, or in this case, refuse to turn on.

Step 1: Check Your Power Outlet

Before delving into intricate solutions, it’s prudent to begin with the basics: the power outlet. Ensure that your power outlet is functioning correctly. You can test this by connecting another device to the same outlet and checking if it powers up.

Step 2: Ensure Secure Connection of Power Cord

Examine the connection between your Onn TV and the power source. Ensure the power cord is securely plugged into the TV and the power outlet. Loose connections can prevent power from reaching your TV, resulting in an Onn TV that won’t turn on.

Step 3: Wait Before Attempting to Power On

Sometimes, an overload can cause your Onn TV to enter a protection mode where it will not respond for a short period. If you suspect this might be the case, disconnect your TV from the power source and wait for about 10-15 minutes before trying again.

Our first quick fix is simple but effective. It addresses a key potential cause for your Onn TV not turning on. It’s also straightforward enough for anyone to carry out.

Quick Fix 2: Clearing TV Cache

You might wonder, “Why won’t my Onn TV turn on?” even when the power supply is perfectly fine. In such cases, the problem may lie in the TV’s software, specifically in the cache. Cache files are temporary data stored by your Onn TV to quickly load frequently used information. However, over time, this cache can become bloated or corrupt, leading to various issues, including preventing your TV from turning on.

Step 1: Power Cycle the TV

Begin by performing a power cycle, which also clears the cache on your Onn TV. This process involves disconnecting your TV from the power outlet, pressing and holding the power button on your TV (not the remote) for about 15 seconds, and then leaving the TV disconnected for another 10 minutes.

Step 2: Reconnect and Power On

After 10 minutes, reconnect the TV to the power outlet and attempt to power it on using the TV’s power button.

Step 3: Use TV Remote

If the TV turns on, use your remote to navigate to Settings > System > Advanced System Settings > Factory Reset. Resetting your TV will clear any remaining cache and return your settings to their default state.

Clearing the cache can be a magic bullet for resolving software-related issues on your Onn TV. However, remember to exercise caution when performing a factory reset as it will erase all personal settings on your TV.

Quick Fix 3: Check Remote Control

Are you convinced that the problem lies with the Onn Roku TV not turning on, rather than any power supply or software issue? In such cases, the issue might be as simple as your TV remote not communicating with your TV. Let’s resurrect that remote!

Step 1: Check Your Remote Batteries

Even the best of us can forget the simplest things, like checking if our remote control batteries are drained. Inspect your remote batteries and replace them if needed.

Step 2: Ensure Optimal Button Performance

Inspect the buttons on your remote control. If any button is

stuck or not functioning properly, it could prevent the remote from sending the correct signal to the TV.

Step 3: Eliminate Obstructions

Ensure there are no obstructions between your remote control and your Onn TV. Infrared remotes require a clear line of sight to work correctly.

If you’ve followed these steps and your remote is still unresponsive, you might want to consider using a universal remote or even a smartphone app that can act as a remote for your Onn TV.

Quick Fix 4: Do A Soft Reset

Sometimes, a simple software reset can work wonders when you’re asking yourself, “why won’t my Onn TV turn on?“. A software reset can effectively resolve minor software glitches that might prevent your Onn TV from turning on.

Step 1: Disconnect Power

Start by disconnecting your Onn TV from the power outlet.

Step 2: Hold Power Button

Next, locate the power button on your Onn TV. Press and hold this button for about 15 seconds.

Step 3: Reconnect and Power On

After releasing the power button, wait for another 10 minutes before reconnecting your TV to the power outlet. Attempt to power on the TV using the TV’s power button.

Resetting the software can be a quick and straightforward way to restore your TV’s functionality. However, it’s important to exercise patience during this process to ensure you follow the steps correctly.

Quick Fix 5: Factory Reset

If the Onn TV won’t turn on no red light, and you’ve exhausted all the previous steps, a factory reset might be your last resort. A factory reset will erase all personal settings and data, restoring your TV to its original out-of-the-box state. This can often fix software glitches that might cause the TV not to turn on.

Step 1: Unplug Your TV

Firstly, disconnect your TV from the power outlet and wait for a few minutes. This ensures that the TV is completely powered off and ready for the next steps.

Step 2: Locate the Reset Button

Next, locate the reset button on your TV. This is typically found on the back or bottom of the unit. You might need a pin or straightened paper clip to press it.

Step 3: Hold the Reset Button

While the TV is still unplugged, press and hold the reset button.

Step 4: Plug the TV Back In

While continuing to hold the reset button, plug the TV back into the power outlet.

Step 5: Release After the Splash Screen

Once you see the brand logo or splash screen appear on the TV, release the reset button. The TV should now restart, and you can proceed with the initial setup process.

A factory reset is a comprehensive fix, addressing multiple potential causes of an Onn TV not turning on. It effectively clears any software-related issues and restores your TV to its initial settings.

Quick Fix 6: Illuminating Backlight Issues

When your Onn TV red light is on but won’t turn on, one of the potential culprits could be a faulty backlight. The backlight illuminates the TV screen, and when it fails, you may end up with a black screen even when the TV appears to be powered on.

Step 1: Conduct a Flashlight Test

To determine if the backlight is the issue, you can perform a flashlight test. Turn on your TV as you would normally, wait a few moments, then shine a flashlight at various angles on the screen. If you can faintly see the TV’s interface, it’s likely that your backlight has failed.

Step 2: Seek Professional Help

Repairing or replacing the backlight on a TV isn’t a user-friendly task and involves dealing with high-voltage components. If the flashlight test confirms a backlight issue, it’s recommended to seek professional help to replace the faulty components.

Dealing with backlight issues can be challenging, and it’s always advisable to seek professional help in such cases to avoid risking further damage to your TV or personal injury.

Quick Fix 7: Reaching Out to Onn Support

If none of the above quick fixes resolve your issue, the problem might be more serious, requiring professional attention. In such cases, reaching out to Onn support can be the most effective solution.

Step 1: Prepare Your TV Details

Before contacting Onn support, prepare your TV model number and a detailed description of the issue you’re facing. This will help the support team understand your issue and provide effective solutions.
