Samsung TV Keeps Freezing

Has your Samsung TV started freezing repeatedly? It’s frustrating when you’re in the middle of a show and the picture suddenly freezes. In this comprehensive guide, I’ll walk you through all the reasons a Samsung TV freezes and show you exactly how to troubleshoot and fix those freezing problems for good.

What Causes a Samsung TV to Freeze?

There are a few common culprits for Samsung TV freezing issues:

Internet Connection Problems

Smart TVs rely on a consistent, fast internet connection. If your Wi-Fi is spotty or drops connection, it can cause freezing. This tends to happen more with streaming apps.

Outdated Apps and Software

Like your smartphone, your Samsung TV needs regular app and software updates. Using outdated apps or an older software version leads to compatibility issues that manifest as freezing screens.


Dust buildup in vents combined with long streaming sessions can cause some Samsung TVs to overheat, resulting in temporary freezing.

Consider getting a temperature controlled TV enclosure if your Samsung TV is in a hot room like a garage to prevent overheating.

Faulty Connections

Loose HDMI cables, damaged ports, cable box issues, or using low-quality third party cables can interrupt signal transfer to your TV, causing freezing.

Too Much Data Storage

Although rare, sometimes smart TVs accumulate too much cached data from streaming apps and services which can slow things down and cause freezing issues.

Now that you know why your Samsung TV keeps freezing, let’s look at how to properly troubleshoot and fix those problems for good.

How to Fix a Samsung TV That Keeps Freezing

Check Your Internet Connection

The vast majority of Samsung TV freezing issues stem from internet connectivity problems.

Here’s how to test for and fix internet issues:

Reset Your Router

Unplug your router and modem, leave them offline for 60 seconds, then reconnect. This cycling often fixes minor ISP hiccups.

Restart The Router

Connect Your TV via Ethernet

For the most reliable signal, use an Ethernet cable rather than Wi-Fi whenever possible.

Connect Your Tv Via Ethernet

Toggle Airplane Mode On and Off

Turn off the TV’s wireless connectivity for a minute via Airplane mode, then turn it back on to reconnect.

Connect to a Mobile Hotspot

Connect To A Mobile Hotspot

Use your smartphone as a Wi-Fi hotspot to isolate the problem. If TV stops freezing when connected only to your phone, issue lies with your home internet setup.

Call Your Internet Service Provider

Contact your ISP to check if they are experiencing service issues in your area. Some connectivity problems originate from them rather than your home network setup.

Once you’ve eliminated internet issues as the culprit, move on to software and app troubleshooting.

Update Apps and Software

Like your smartphone operating system, your smart TV platform needs constant software and firmware updates to fix bugs and improve performance.

App developers also regularly release new versions of apps like Netflix and YouTube to patch issues.

Here’s how to update your Samsung TV’s apps and system software:

Check Your Samsung TV’s Software Version

From the home screen menu:

  1. Select Settings
  2. Choose Support
  3. Click Software Update
  4. Select Update Now to install any available updates
Software Update Samsung Tv

Enable Auto Software Updates

Your TV should automatically check and install updates but toggling this on ensures it:

  1. Open Settings
  2. Choose Support
  3. Select Software Update
  4. Click on Auto update to toggle it on
Auto Update Samsung Tv

Update Apps Individually

You can also manually update any app:

  1. Highlight the app icon
  2. Press and hold Enter button
  3. Choose Update

Streaming services like Netflix, Hulu and Disney+ regularly patch bugs and release new app versions you need to install.

Once software and apps are updated, check if TV still freezes. If not, problem solved!

If it still freezes after updating, try resetting your TV next.

Reset Your Samsung TV

Resetting your Samsung TV restores factory default settings which often resolves freezing issues caused by problematic customized configurations.

Soft Reset

The fastest way is a soft reset:

  1. Press and hold power button on Samsung TV until screen fully turns off
  2. Unplug TV power cable and leave unplugged for 2 minutes
  3. Plug power back in and turn TV on
Unplug The TV

Hard Reset

If soft reset doesn’t work, do a factory reset:

  1. From TV menu, select Settings > General > Reset
  2. Enter default PIN code: 0000
  3. Choose Reset to restore factory defaults
Factory Reset Your Samsung Tv

Resetting deletes all personal data and settings. You’ll have to reinstall apps and reconfigure options afterward. Check if it stopped the freezing problem.

Check Connections and Cables

Freezing issues can also arise from loose cable connections. Carefully inspect the following:

HDMI Ports

Make sure HDMI cables connecting devices like your cable box, game console, or Blu-ray player are undamaged, firmly plugged in, and inserted in the correct ports.

Hdmi Ports Samsung Tv

TV Power Cable

Ensure power cable is fully inserted into the TV and wall outlet. Try disconnecting and reconnecting.

Cable Box Cables

If you use a cable box, double check all connections running from box to TV, including HDMI cable and power cord.

Wi-Fi Router Connection

If using Wi-Fi, make sure your Samsung TV’s connection is strong. If not, connect an Ethernet cable directly from your router to establish a more reliable wired connection.

Check cable connections to isolate the freezing trigger. If problems persist, dust buildup may be causing overheating issues.

Clean Dust Buildup

Dust accumulation within the TV’s internal components forces the fans to work harder. This overheats the system and causes temporary freezing.

Carefully clean dust using these steps:

  1. Unplug the Samsung TV
  2. Use a soft brush attachment on a vacuum cleaner to gently remove dust from ventilation openings along the back and sides. Never insert anything into ports!
  3. Use a can of compressed air to spray out any remaining dust inside the vents and gaps between components
  4. Reconnect and turn on TV to check if overheating freezes are fixed

Avoid blowing air directly at sensitive electronic modules. Be very gentle when handling rear vents.

If you don’t feel comfortable doing this yourself, contact Samsung support for cleaning assistance.

Contact Samsung Support

If you still face freezing problems after trying the above fixes, contact Samsung TV technical support.

Describe the issue and troubleshooting steps you took. Their experts can provide specialized remote troubleshooting, schedule technician visits for complex repairs like motherboard issues, or guide you on replacement options if they determine your older TV is beyond cost-effective fixes.

I know Samsung TV freezing errors are endlessly frustrating, especially if rebooting and basic steps don’t permanently resolve them. Carefully trying the fixes above should isolate the culprit 95% of the time. Reach out for assistance if problems continue!
