Samsung TV Error Codes: Complete Troubleshooting Guide

Modern Samsung TVs are sophisticated devices with dozens of internal sensors and modules. When something goes wrong, an error code appears on screen. In this guide, we'll break down all major Samsung TV error codes, explain what they mean, and show you how to fix the problem yourself — or when it's time to call a professional repair service.

Samsung TV Error Code Quick Reference Table

Error Code 0-1 and 7-1: Smart Hub Failure

This is one of the most common Samsung TV errors. It's related to Smart Hub — the platform for apps and streaming services.

How to fix it:

1. Press the Home button on your remote
2. Go to Settings → Support → Self Diagnostics
3. Select Reset Smart Hub
4. Enter the PIN code (default is 0000)
5. Wait for Smart Hub to restart

If the problem persists after the reset, try a full factory reset: Settings → General → Reset. Note that this will erase all settings and accounts.

Codes 001, 012, 102, 105, 110: Network Problems

Most Samsung Smart TV errors are related to internet connectivity. Here's a universal troubleshooting process:

Step 1: Check your router

• Restart your router (unplug for 30 seconds, plug back in)
• Make sure other devices connect to Wi-Fi successfully

Step 2: Check network settings on the TV

• Settings → General → Network → Network Status — run the diagnostic
• If Wi-Fi won't connect, try entering your password again

Step 3: Change DNS server

• Go to Settings → General → Network → Network Status → IP Settings
• Select DNS Settings → Enter Manually
• Enter 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS)

Step 4: Update firmware

• Settings → Support → Software Update → Update Now
• If there's no internet — download the firmware onto a USB drive from samsung.com

Error Code 107, 116, 301: Updates and Authorization

These errors usually mean the TV firmware is outdated or there's an authorization problem with Samsung services.

Solution:

1. Check for updates: Settings → Support → Software Update
2. If automatic update doesn't work, download the update from samsung.com/support onto a USB drive (FAT32 format)
3. Insert the USB drive into the TV's USB port
4. Go to Settings → Support → Software Update → Update Now

Samsung TV Blinking Red Light: Decoding the Signals

If the TV won't turn on but the red indicator is blinking, the number of blinks indicates the type of problem:

What you can try:

• Unplug the TV from the wall outlet for 60 seconds
• Disconnect all external devices (HDMI, USB)
• Plug the TV directly into the wall outlet (not through a power strip or surge protector)

Important: If you see 5-6 blinks — this could be a backlight failure. Shine a flashlight on the screen: if you can see a faint image, the backlight has failed. In this case, repair is possible — the LED strips need to be replaced.

Samsung TV Turns On and Off by Itself

This problem is more common than you might think. Possible causes:

1. Sleep timer — check: Settings → General → System Manager → Time → Sleep Timer
2. Eco mode — disable: Settings → General → Eco Solution → Auto Power Off
3. Anynet+ (HDMI-CEC) — devices connected via HDMI can turn the TV on/off: Settings → General → External Device Manager → Anynet+
4. Power supply issue — swollen capacitors (requires professional repair)

Samsung TV No Sound Through HDMI ARC

If you've connected a soundbar or receiver via HDMI ARC and there's no sound:

1. Make sure the HDMI cable is plugged into the port labeled ARC (usually HDMI 3)
2. Enable HDMI-CEC (Anynet+): Settings → General → External Device Manager
3. Change audio output: Settings → Sound → Sound Output → select Receiver/Audio System
4. Try a different HDMI cable (recommended: HDMI 2.1 for eARC support)

When to Call a Professional Repair Service

Some problems can't be fixed at home. Signs that your TV needs professional repair:

• Cracked or broken screen — panel replacement needed
• Vertical or horizontal lines that don't disappear after restart — T-Con board or panel issue
• TV won't turn on at all (no indicator light) — power supply problem
• 5-6 red blinks — backlight failure
• Burning smell — immediately unplug and bring to a repair shop
• Sound works but no picture — Main Board or backlight problem
