Samsung TV Error 103 — What It Means & How to Fix It

What Does This Error Mean?

Error 103 means two devices on your network have been assigned the same IP address. When two devices share an IP, the TV cannot communicate properly with the router. Restarting the router or assigning the TV a unique static IP address resolves Error 103.

Common Causes

Another device on the network was manually assigned the same IP the router gave the TV
The router's DHCP server assigned the same IP to two devices due to a lease table error
A device that left the network did not release its IP, and the router reused it for the TV
A second router or access point on the network is running its own DHCP server
The TV was manually configured with a static IP that overlaps with another device's address

How to Fix It

Restart your router by unplugging it for 30 seconds — this clears the DHCP lease table and reassigns fresh IPs.

Most IP conflicts are resolved by a router restart because the DHCP server starts fresh with clean assignments.
On the TV, go to Settings > General > Network > Reset Network to release the conflicting IP address.

Resetting the network forces the TV to request a brand-new IP address from the router.
After resetting, reconnect to Wi-Fi and check if Error 103 appears again.

If the error returns immediately, another device is likely manually configured with the same IP.
Check your router's admin panel for any devices with manually assigned (static) IPs that might overlap with the TV's address.

Look for a 'DHCP Reservations' or 'Static IP' section in the router's LAN settings.
Assign the TV a static IP address that is outside the router's DHCP range to permanently avoid conflicts.

Go to Settings > General > Network > IP Settings > Enter Manually and use an IP like 192.168.1.200 with DNS 8.8.8.8.
If you have more than one router or access point, ensure only one is running a DHCP server.

Two DHCP servers on the same network will assign conflicting addresses to devices — disable DHCP on the secondary device.

When to Call a Professional

Contact your router manufacturer if the DHCP server keeps generating IP conflicts after rebooting. Samsung Support can help reconfigure the TV's network settings if the conflict cannot be resolved at home. A network technician can audit all devices on the network to identify and eliminate duplicate IPs.

Frequently Asked Questions

What is an IP address conflict and why does it cause problems?

Every device on a network needs a unique IP address — like a unique house number on a street. If two devices share the same IP, the router does not know which one to send data to. Error 103 appears because the TV cannot send or receive data reliably when it shares an address.

Can adding a new device to the network cause Samsung TV Error 103?

Yes — if you add a device and manually give it an IP that the router already assigned to the TV, a conflict occurs. Always let the router assign IPs automatically, or check the router's current assignments before setting a static IP. Using a static IP outside the router's DHCP range (such as 192.168.1.200+) prevents this entirely.

Will Error 103 go away on its own?

Sometimes — if the conflicting device disconnects, the TV may reconnect without the error. However, the conflict will return whenever that device reconnects to the network. The permanent fix is to assign the TV a unique static IP or adjust the router's DHCP settings.
