Why Is My Samsung Smart TV Flickering Black for a Few Seconds Per Minute?

Many users have reported experiencing occasional flickering issues with their Samsung Smart TVs. Moments of black-on-black or dark flickering can be both annoying and concerning. In this article, we will explore various potential causes and steps to troubleshoot this issue, focusing on software, hardware, and content sources.

Understanding the Symptoms

When a Samsung Smart TV flickers black, it means that the display briefly goes black or shows reduced brightness. This happens about 5 times a minute. Such behavior is not typical of a normal viewing experience and often indicates a problem with either the hardware, software, or the content source.

The frequency and duration of the flickering can vary. Knowing when it happens and the pattern can help in diagnosing the issue more effectively. For example, if it occurs only at certain times or with specific channels, it may point to a more targeted problem, such as a bad power supply for that particular input source.

Common Causes of Samsung TV Flickering

Software Issues

Software issues can sometimes cause temporary display glitches on a Samsung Smart TV. These can be due to:

Outdated Firmware: The TV's firmware might need an update to resolve compatibility or stability issues with certain content or services. Gaming Mode or Service Mode: These modes could interfere with the regular display and cause flickering. Try turning these modes off to see if the issue persists. Content Streaming: Certain streaming services, particularly those using adaptive streaming, might cause temporary blips in the display. This could be temporary and resolve itself once the content source reloads.

Hardware Problems

Hardware issues can also lead to flickering on a Samsung Smart TV. These may include:

Power Supply Issues: A bad power supply could cause the TV to briefly cut off or dim, leading to flickering. Ensuring that the power supply is stable and correctly connected can help. TV Components: The LCD, LEDs, or other components could be malfunctioning. In such cases, replacing or repairing these components may be necessary.

Content Source Issues

External content sources, such as a Roku, Fire Stick, or other media streaming devices, can also contribute to flickering issues. Common causes include:

Incompatible Devices: If your external device is not compatible with your Samsung Smart TV or if it has outdated drivers, it could cause flickering. Ensure that the device is up-to-date and properly connected. Input Cable Issues: Poor quality or loose connections can lead to intermittent signals, causing the TV to flicker. Double-check all connections and ensure that your cables are of good quality.

Troubleshooting Steps

Here are some steps you can take to troubleshoot the flickering issue on your Samsung Smart TV:

Check Recent Updates: Ensure that your TV's firmware is up-to-date. You can check for updates through the settings menu. If available, install the latest firmware to resolve any software-related glitches. Rename Your Router: Sometimes, simply renaming the Wi-Fi network can help resolve issues with streaming content. Try changing your router's SSID and see if the flickering stops. Check for Malware: Malware or viruses can sometimes cause unexpected behavior. Run a full system scan to ensure that your TV is free from such issues. Reset Factory Settings: As a last resort, you may need to reset your TV to factory settings. This step erases all custom settings and downloaded content, so make sure to back up anything important first.

By following these steps, you can often identify and resolve the source of the flickering issue on your Samsung Smart TV. If the problem persists, it may be useful to consult a professional technician or contact Samsung's customer support.
