How to Fix LG TV 'Device Connected but No Files Found' (DLNA Diagnostic)

The Paradox: The TV Sees Your Phone, but the Folders Are Empty

You launch the Media Player or SmartShare app on your LG OLED or QNED TV. Under Connected Devices, your phone's media server appears with a green connected badge. You click on it with your LG Magic Remote, expecting to browse your photo albums or home video clips.

Instead, after a brief loading animation, your screen displays the frustrating error:

Why does this happen when your phone's media server is actively running and clearly visible on the television?

Understanding the UPnP Pipeline: Discovery vs. Content Directory

To understand why this error occurs, it is essential to look at the two distinct phases of the UPnP AV protocol:

1

1. Phase 1: Discovery (SSDP): Your phone broadcasts a UDP multicast announcement across the local network (239.255.255.250:1900). Your LG TV hears this packet, learns your phone's IP address, and displays your server name in the Home Dashboard. Discovery has succeeded!
2. Phase 2: Content Directory Browse (SOAP/HTTP): When you click on the server icon, the TV issues an HTTP POST request to the server's /ContentDirectory/control endpoint executing a SOAP Browse action for Container ID 0 (root). The server must reply with an XML document formatted according to the DIDL-Lite specification.

If the server's response contains even a single syntax imperfection, a mismatched MIME type, or an unescaped character, the LG webOS XML parser silently aborts and declares: "No Files Found".

The 4 Technical Root Causes of "No Files Found" on LG TVs

1. Malformed DIDL-Lite XML & Missing upnp:class

LG webOS strictly validates the XML element structure inside the <DIDL-Lite> envelope:

• Every container must specify id, parentID, restricted="1", and an integer childCount.
• Every video file must explicitly declare <upnp:class>object.item.videoItem</upnp:class>. If a server provides a generic object.item, the webOS video player filters it out.
• Every photo must declare <upnp:class>object.item.imageItem.photo</upnp:class>.

2. Unescaped XML Characters in File & Collection Names

If your vacation collection is named "Mom & Dad's 50th" or contains video files with symbols (<, >, &, "), a poorly coded media server will inject raw characters into the XML stream. The LG XML parser encounters an unexpected entity error, terminates parsing halfway through the list, and renders an empty screen.

3. The HEIC / HEIF Format Mismatch

Modern iPhones shoot photos exclusively in Apple's High Efficiency (HEIC) image container. Generic DLNA media servers simply serve the raw .heic file with image/heic MIME headers. Because LG webOS image hardware decoders only support JPEG and PNG, webOS hides the unsupported files completely.

4. Stale webOS Cache & Quick Start+ RAM State

LG's Quick Start+ feature maintains the television's operating system in a low-power suspended RAM state rather than completing a real shutdown. If a media server's IP address or container structure changed, webOS continues querying outdated container IDs cached in memory, yielding zero results.

5-Step Diagnostic & Resolution Checklist

Step 1: Check the Active Tab Filter in LG Media Player

Inside the LG Media Player app, inspect the top-right navigation tabs. webOS provides separate views for All, Photos, Videos, and Music. If the tab is set to "Photos" and your collection only contains 4K MP4/MOV clips, the folder will falsely show "No Files Found". Switch the filter to All or Videos.

Step 2: Disable Quick Start+ and Cold Reboot the TV

1. On your LG remote, press the Gear icon (Settings) > All Settings.
2. Navigate to General > Devices > TV Management (or System on newer webOS).
3. Toggle Quick Start+ to OFF.
4. Unplug the TV power cord from the wall outlet for 60 seconds to discharge internal capacitors and clear volatile memory.
5. Plug the TV back in and power it on.

Step 3: Ensure Clean XML Escaping on the Media Server

If you are running a custom server or third-party tool, verify that all strings passed to the Content Directory are strictly sanitized using standard XML entity encoding:

• & → &
• < → <
• > → >
• " → "

Step 4: Check Subnet and AP Isolation

Verify that your phone and LG TV are connected to the same Wi-Fi SSID. In your Wi-Fi router settings, confirm that AP Isolation or Guest Mode is disabled, allowing local devices to exchange bi-directional TCP data.

Step 5: Use Zee Cast for Guaranteed LG webOS Compatibility

Zee Cast was built and validated against every generation of LG webOS (from webOS 4.0 on vintage OLEDs through webOS 24 on current G4/C4 models):

• Byte-Exact DIDL-Lite Generation: Generates flawless XML envelopes with complete upnp:class, res protocolInfo, and childCount compliance.
• Automated HEIC → JPEG Conversion: Converts iPhone HEIC photos into pristine, high-resolution JPEGs on-the-fly, ensuring every photo opens instantly on LG TVs.
• Strict XML Sanitization: Automatically escapes all user-defined collection names and metadata, preventing parser crashes.
• Bit-Perfect Direct Play: Delivers raw 4K 60fps HEVC and Dolby Vision Profile 8.4 video bitstreams via standard HTTP Range requests with zero buffering.
