LG OLED G3 Error Code 105

If your LG OLED G3 error code 105 keeps appearing, you're likely experiencing network connectivity issues that prevent streaming apps, firmware updates, and smart features from working properly. This error typically indicates that your TV cannot establish a stable connection to LG's servers or the internet, even when other devices in your home are online. The good news is that this is usually fixable without professional repair. Follow the troubleshooting steps below to restore full functionality to your LG OLED G3 television.

What Causes Error Code 105 on LG OLED G3 TVs?

The LG OLED G3 error code 105 most commonly stems from DNS resolution failures, router conflicts, outdated TV software, or temporary server outages on LG's end. Because the G3 series relies heavily on webOS and cloud-based services, any interruption in this communication chain triggers this specific error. Understanding the root cause helps you apply the right fix efficiently rather than trying random solutions.

Step-by-Step Troubleshooting for LG OLED G3 Error Code 105

Restart Your TV and Network Equipment: Unplug your LG OLED G3 from power for at least 60 seconds. Simultaneously, unplug your modem and router. Wait 30 seconds, then reconnect your modem first, followed by your router once the modem fully boots. Finally, plug your TV back in. This clears temporary cache conflicts and refreshes IP assignments.

Verify Network Connection Status: Press the Settings button on your remote, navigate to Network → Wi-Fi Connection or Wired Connection, and check if the TV shows "Connected to Internet." If it shows only "Connected to Network" without internet access, the issue lies between your router and LG's servers. Try switching from Wi-Fi to Ethernet temporarily to isolate wireless interference.

Change DNS Settings to Public DNS: Go to Settings → Network → [Your Connection] → Advanced Settings → DNS Setting, then select "Set Manually." Enter 8.8.8.8 as the primary DNS and 8.8.4.4 as the secondary (Google DNS), or use 1.1.1.1 and 1.0.0.1 (Cloudflare). Save and restart the TV. LG's default DNS servers occasionally experience routing issues that trigger error code 105.

Update webOS Firmware: Navigate to Settings → Support → Software Update → Check for Updates. If your TV cannot reach update servers due to the error, download the latest firmware from LG's support website onto a USB drive, insert it into your G3's USB port, and install manually. Outdated firmware often contains resolved networking bugs.

Reset Network Settings and Reconfigure: Go to Settings → General → Reset to Initial Settings → Network Settings. This erases saved Wi-Fi passwords and custom network configurations. Reconnect to your network fresh, avoiding special characters in passwords that occasionally cause parsing errors on webOS 22/23.

Check for Service Outages and Adjust Time/Date: Verify LG server status through their system status page or community forums. Additionally, ensure your TV's clock is accurate at Settings → General → Date & Time → Set Automatically. Incorrect timestamps cause SSL certificate validation failures that manifest as error code 105 during server handshakes.

Warning: Performing a full factory reset will erase all installed apps, login credentials, and personalized settings. Only use this as a last resort if the above steps fail to resolve your LG OLED G3 error code 105 issue. Back up any important configuration details beforehand.

Advanced Troubleshooting Tips

If basic steps don't eliminate the LG OLED G3 error code 105, examine your router's firewall and parental control settings. Some routers with AiProtection, Circle, or similar features block LG's content delivery network domains. Whitelist domains including *.lge.com, *.lgappstv.com, and *.yumenetworks.com. Disable IPv6 on your router if enabled, as webOS sometimes prioritizes problematic IPv6 routes. For mesh network users, ensure your G3 connects to the nearest node—weak backhaul connections between mesh points cause intermittent server timeouts.

Frequently Asked Questions

Why does LG OLED G3 error code 105 appear only when using certain apps?

Individual apps like Netflix, Disney+, or LG Channels may use different content delivery endpoints. If error code 105 appears selectively, the app's specific servers or your ISP's routing to those servers may be at fault. Try the affected app during off-peak hours or contact your ISP about routing issues.

Can a weak Wi-Fi signal cause error code 105 even if the TV says it's connected?

Yes. Marginal Wi-Fi strength causes packet loss during server authentication, triggering error code 105 despite showing a connection. Check signal strength at Settings → Network → [Connection] → Advanced Settings. If below -70 dBm, move your router closer, remove obstructions, or switch to 5GHz band if currently on 2.4GHz.

Does error code 105 indicate a defective LG OLED G3 that needs replacement?

Rarely. This error is overwhelmingly software and network-related. Hardware failure would typically produce additional symptoms like complete Wi-Fi adapter failure (no networks detected) or persistent crashes. If you've exhausted all troubleshooting and other devices work fine on the same network, then professional diagnostic service may be warranted.
