LG TV Error Code 501 indicates that your TV's Smart Share feature cannot detect or display content from connected devices such as USB drives, network-attached storage, or DLNA media servers. This typically happens due to network misconfiguration, outdated firmware, incorrect Smart Share settings, or compatibility issues between the TV and the media source. The good news is that this is almost always a software or settings issue you can resolve at home without any special tools.

Tools You'll Need

How to Fix Error Code 501

  1. Restart Your LG TV and Connected Devices

    Always unplug the TV from the wall rather than relying on standby mode for a true power reset.

  2. Check and Enable Smart Share Settings on the TV

  3. Confirm Your TV and Media Device Are on the Same Network

  4. Update LG TV Firmware

    Do not unplug the TV or remove the USB drive during a firmware update — this can permanently damage the TV's software.

  5. Configure Your Media Server or PC for DLNA Sharing

  6. Check USB Drive Format and File Compatibility

  7. Reset Smart Share / Network Settings on the TV

    A full factory reset will erase all app logins, settings, and preferences. Try a network-only reset first.

  8. Temporarily Disable Firewall or Security Software

    Only disable firewall software temporarily for testing. Always re-enable it after the test.

When to Call a Professional

If you have completed all steps above and your LG TV still shows Error 501 with no Smart Share content visible, and the issue persists across multiple media sources and connection methods (USB, Wi-Fi, Ethernet), the TV's internal network module or Smart Share software may have a hardware-level fault. Contact LG Support at 1-800-243-0000 or visit an LG-authorized service center. If your TV is under warranty, do not attempt internal repairs as this will void coverage. A certified technician can run deeper diagnostics, reflash the TV's firmware at a system level, or replace the internal network/Wi-Fi module if needed.

Frequently Asked Questions

Why does my LG TV Smart Share show no devices even though my PC is on the same network?
This usually happens because media streaming is not enabled on your PC, or your Windows Firewall is blocking DLNA discovery. Open Windows Media Player, click 'Stream' in the top menu, and select 'Turn on media streaming.' Also check that Network Discovery is enabled in your PC's Network and Sharing Center settings. After enabling these, refresh the device list on your LG TV's Smart Share.
Does LG TV Error 501 mean my TV is broken?
No — Error 501 is almost always a software, network, or settings issue rather than a hardware failure. It means the TV's Smart Share feature cannot locate or access your media content. Following the troubleshooting steps to check network settings, enable DLNA sharing, and update firmware resolves this error in the vast majority of cases.
What file formats does LG TV Smart Share support?
LG Smart TVs support a wide range of formats including MP4, MKV, AVI, MOV, and TS for video; MP3, AAC, FLAC, and WAV for audio; and JPEG, PNG, and BMP for images. However, not all codecs within these containers are supported. For example, MKV files with certain audio codecs like TrueHD or DTS-MA may not play. If a specific file won't show or play, try converting it to H.264 MP4 using free software like HandBrake.
Can I use Smart Share over a 5 GHz Wi-Fi connection on my LG TV?
Yes, if your LG TV supports 5 GHz Wi-Fi (most models from 2016 onward do), you can use it for Smart Share. The key requirement is that both your LG TV and your media source device must be connected to the same network. If your router broadcasts separate SSIDs for 2.4 GHz and 5 GHz, make sure both devices are on the same one, or connect your TV to Ethernet for the most reliable Smart Share performance.
Will a factory reset fix LG TV Error 501?
A factory reset can fix Error 501 if the cause is corrupted Smart Share settings or a software glitch, but it should be a last resort because it erases all your apps, logins, and preferences. Try a network-only reset first via Settings > Connection > Network > Reset Network Settings. If that does not work, perform a full factory reset via Settings > General > Reset to Initial Settings and then reconfigure your network and Smart Share settings from scratch.
