Experiencing a TV that turns off and on by itself can be both frustrating and perplexing. If you own a Samsung QN55Q70TAFXZA, you might find yourself in this situation. Not only does this issue disrupt your viewing experience, but it can also raise questions about the reliability and functionality of your device. In this comprehensive guide, we'll explore the possible reasons behind your TV's erratic behavior, provide solutions, and offer insights to help you make the most out of your Samsung QN55Q70TAFXZA.
Understanding the Samsung QN55Q70TAFXZA
Before we dive into troubleshooting, let’s take a moment to understand what makes the Samsung QN55Q70TAFXZA a popular choice among consumers. This 55-inch QLED TV, part of Samsung's Q70 series, is known for its stunning picture quality, vibrant colors, and impressive brightness levels. With Quantum HDR technology, a sleek design, and smart features integrated into Samsung's Tizen operating system, it has become a go-to model for many homeowners seeking an immersive viewing experience.
However, like any electronic device, it’s not immune to problems. One common issue is when the TV turns off and back on by itself, which can stem from various reasons ranging from simple user error to more complex hardware malfunctions.
Common Causes of the Issue
Power Supply Issues
One of the primary reasons your Samsung QN55Q70TAFXZA might be turning off and on by itself is related to the power supply. Fluctuations in power can lead to the TV shutting down unexpectedly. If the power cord is loose or if there are issues with your electrical outlet, the TV might interpret this instability as a signal to turn off.
What to Check:
- Power Cord: Ensure that the power cord is securely plugged into both the wall outlet and the TV.
- Outlet Functionality: Test the outlet with another device to ensure it’s working correctly.
- Surge Protectors: If you’re using a surge protector, it could be malfunctioning. Try plugging the TV directly into the wall.
Software Glitches
Sometimes, software issues can cause your TV to behave erratically. Firmware bugs or outdated software may result in unexpected restarts. Samsung regularly releases updates to improve functionality and fix bugs, which can be crucial in addressing these types of problems.
What to Check:
- Software Update: Navigate to Settings > Support > Software Update. Check if there are any available updates and install them if necessary.
Remote Control Problems
Sometimes, a malfunctioning remote control can inadvertently send signals to your TV, causing it to turn off and on. A stuck button or an issue with the remote’s batteries could be the culprit.
What to Check:
- Remote Control: Remove the batteries from your remote and check if the issue persists. If the TV behaves normally without the remote, you may need to replace it.
- Smartphone Apps: If you are using a smartphone app as a remote, ensure it’s functioning correctly and not sending errant signals.
External Devices
Any external device connected to your Samsung QN55Q70TAFXZA—be it a gaming console, soundbar, or streaming device—can cause your TV to turn off unexpectedly. These devices may also be sending signals that disrupt the TV's normal operations.
What to Check:
- Disconnect External Devices: Try disconnecting all external devices to see if that resolves the issue. If the TV operates normally, reconnect the devices one by one to identify the problematic one.
Hardware Malfunctions
If you’ve gone through all the basic checks and the problem persists, you may be dealing with a hardware issue. Components within the TV, such as the power supply board, can fail and lead to instability.
What to Check:
- Professional Inspection: If your TV is still under warranty, consider contacting Samsung for a service appointment. A professional technician can assess and resolve hardware-related issues.
Troubleshooting Steps
Now that we've established potential causes, let’s outline specific troubleshooting steps to help you resolve the issue of your Samsung QN55Q70TAFXZA turning off and on.
Step 1: Power Reset
One of the simplest solutions to various tech issues is a power reset.
- Turn off your TV and unplug it from the wall outlet.
- Wait for at least 60 seconds.
- While unplugged, press and hold the power button on the TV for about 30 seconds to discharge any remaining power.
- Plug the TV back in and turn it on.
Step 2: Update Software
To update your TV’s software:
- Press the Home button on your remote.
- Navigate to Settings > Support > Software Update.
- Select “Update Now” to check for available updates.
Step 3: Factory Reset
If the issue persists after trying the above steps, a factory reset can help eliminate software-related problems. Keep in mind that this action will erase all your settings and data.
- Press the Home button on your remote.
- Go to Settings > General > Reset.
- Follow the prompts to complete the reset.
Step 4: Check for Overheating
Overheating can also lead to automatic shut-offs. Ensure that the TV has adequate ventilation. Clean any dust from vents and avoid placing it in enclosed spaces.
Step 5: Seek Professional Help
If your TV continues to malfunction after exhausting these troubleshooting options, it may be time to seek professional assistance. Contact Samsung support or a certified technician to diagnose the issue.

To prevent future occurrences of your Samsung QN55Q70TAFXZA turning off and on by itself, consider implementing the following measures:
