How to fix LG TV error code 137 step by step

By /

LG TV Error Code 137 typically appears when you try to open the YouTube app and indicates that the application failed to launch or crashed, often due to internet issues, an outdated app version, or corrupted cache. It is not a general “system failure” code but is mostly tied to webOS‑specific YouTube or streaming‑app behavior. Here is a practical, step‑by‑step fix you can follow on your LG smart TV.

Step 1: Check internet connection and restart TV/router

  1. Verify other devices have internet

    • Test your phone, laptop, or tablet on the same Wi‑Fi or router.

    • If they also have no internet, fix the router or ISP side first.

  2. Restart the LG TV and router

    • Turn off the TV using the remote.

    • Unplug the TV from the wall, press and hold the front power button for 10–15 seconds, then wait 60 seconds before plugging it back in.

    • Unplug the router for 1–3 minutes, then plug it back in and wait for all lights to stabilize before turning the TV on.

Try opening YouTube again after the restart; if Error 137 disappears, the issue was likely a temporary network or session glitch.

Step 2: Update or reinstall the YouTube app

Error 137 often appears when the YouTube app is out of date or has corrupted files.

  1. Open LG Content Store

    • Press Home on the remote → select LG Content Store (or More Apps / Apps depending on your webOS version).

  2. Update or reinstall YouTube

    • Go to Apps → My Apps → locate YouTube.

    • If an Update button appears, tap it and let the update finish.

    • If there is no update or the error persists, uninstall YouTube and then reinstall it from the Content Store.

After reinstalling, launch YouTube and see whether Error 137 returns; most users report that an update or clean reinstall clears the code.

Step 3: Clear YouTube cache and app data

Corrupted cache or app data can also trigger Error 137.

  1. Clear cache

    • Press Home → Settings → General → System settings → Application manager (or similar).

    • Select YouTube → choose Clear cache (and sometimes Clear data if available).

  2. Test YouTube again

    • After clearing, open YouTube once more and try to play a video. If the error is gone, the problem was in the app’s local data.

If you still see Error 137, the issue is likely deeper in the TV’s software or network stack.

Step 4: Check date, time, and network settings

Incorrect date/time or unstable DNS can confuse streaming apps and cause crashes.

  1. Verify date and time

    • Go to Settings → General → Date & Time → set to Automatic (Synchronize with network). If the TV cannot sync, set it manually and match your local time.

  2. Tweak Wi‑Fi or switch to Ethernet

    • In Settings → Network → Wi‑Fi settings, try forgetting the current network and reconnecting.

    • If possible, connect the TV to the router using an Ethernet cable instead of Wi‑Fi to rule out wireless instability.

    • You can optionally change the DNS on the TV to a public DNS (for example, Google DNS or Cloudflare) if your router allows it.

If Error 137 clears after switching to Ethernet or fixing DNS, your Wi‑Fi environment was the root cause.

Step 5: Factory reset only as last resort

If none of the above steps work, the issue may be a corrupted system file or deeper software fault, and the safest final user step is a factory reset.

  1. Backup your notes

    • Note down Wi‑Fi passwords, account logins, and custom picture/sound settings; they will be erased.

  2. Perform a factory reset

    • Go to Settings → General → Reset to initial settings (or Factory reset).

    • Enter the security key when prompted (often 0000 or 1234, depending on model), and confirm.

    • Let the TV complete the reset; do not power it off during the process.

After the reset, set up the TV again, install the latest YouTube app, and test streaming. In many cases, Error 137 vanishes after a full reset because corrupted app or system files are wiped.

If Error 137 persists even after a factory reset and updated app, the fault may lie in the TV’s main board, webOS boot partition, or firmware, which requires a technician or service center. For LG TV owners in Nairobi and surrounding areas, contacting a qualified repair service like Pro‑Logic Technologies ensures the TV is diagnosed safely before any hardware intervention.
