The Samsung TV error code SCT stands for Screen Tearing Detected, and it means your TV is displaying visual artifacts where the image appears split or misaligned horizontally — as if two frames are being shown at once. This typically happens due to a mismatch between the TV's refresh rate and the frame rate of the signal it's receiving from a connected device, or due to software, HDMI, or display panel issues. In most cases, this is a software or settings problem you can fix yourself at home without any special tools.

Tools You'll Need

How to Fix Error Code SCT

  1. Restart Your Samsung TV

    Do not repeatedly power cycle the TV in rapid succession, as this can stress internal components. Wait a full 60 seconds before plugging back in.

  2. Check and Replace the HDMI Cable

  3. Adjust the Picture Settings and Game Mode

  4. Disable or Enable VRR and FreeSync/G-Sync

  5. Update Your Samsung TV Firmware

    Do not turn off the TV or unplug it during a firmware update. Interrupting the update can corrupt the TV's software and may require a factory service repair.

  6. Perform a Picture Test

  7. Factory Reset the TV

    A factory reset erases all personalized settings and downloaded app data. Write down your network passwords and any custom picture settings before proceeding.

When to Call a Professional

If the SCT screen tearing error persists after completing all steps above — including the factory reset — and the built-in Picture Test shows tearing on the test image itself, the problem is likely a failing T-Con board, loose internal ribbon cable connection, or a defective display panel. These are internal hardware issues that require a Samsung-certified technician to diagnose and repair. You should also contact a professional if your TV is still under Samsung's standard warranty (typically 1 year) or if you purchased Samsung Care+ extended protection, as attempting internal repairs yourself may void coverage. Contact Samsung Support at 1-800-726-7864 or visit Samsung's service locator to find an authorized repair center.

Frequently Asked Questions

What does SCT mean on a Samsung TV?
SCT on a Samsung TV stands for Screen Tearing Detected. It indicates that the TV has detected a visual sync issue where the display is showing parts of two different frames at the same time, resulting in a horizontal split or misaligned image. This is usually caused by a refresh rate mismatch, a bad HDMI cable, incorrect picture settings, or outdated firmware.
Why is my Samsung TV showing screen tearing all of a sudden?
Sudden screen tearing on a Samsung TV is most often caused by a recent firmware glitch, a newly connected device with incompatible frame rate settings, a failing HDMI cable, or a change in Game Mode or VRR settings. Try restarting the TV, swapping the HDMI cable, and checking that your firmware is up to date. If it started after a firmware update, a factory reset may restore normal operation.
Does Samsung TV screen tearing mean the TV is broken?
Not necessarily. In the majority of cases, screen tearing on a Samsung TV is caused by a software, settings, or cable issue — not a broken panel. Only if the tearing appears during Samsung's built-in Picture Test (found under Settings > Support > Self Diagnosis) does it suggest a potential hardware problem with the T-Con board or display panel. Work through the software fixes first before assuming the TV is defective.
Can a bad HDMI cable cause screen tearing on a Samsung TV?
Yes, absolutely. A damaged, low-quality, or non-certified HDMI cable is one of the most frequent causes of screen tearing. If the cable cannot reliably transmit the full bandwidth required by your video signal — especially at 4K 60Hz or higher — it can cause sync errors that appear as tearing. Always use a certified High Speed HDMI cable rated for your resolution and refresh rate, and inspect cables for any physical damage.
Will a factory reset fix Samsung TV screen tearing?
A factory reset can fix screen tearing on a Samsung TV if the cause is corrupted settings, a software misconfiguration, or a problematic firmware state. It restores all picture and system settings to their factory defaults, which eliminates any user-introduced setting combinations that might be causing the sync issue. However, if the tearing is caused by a hardware fault — such as a failing T-Con board — a factory reset will not resolve it.
