LG TV Error 137 on the YouTube app means the application failed to launch or crashed when you tried to open it, usually due to internet issues, an outdated app version, or corrupted local data. The good news is that in most cases this can be fixed from the TV itself without opening the panel. Below is a focused, step‑by‑step YouTube‑app‑only fix you can apply on an LG webOS TV.
1. Quick check: internet and router
-
Confirm that other devices (phone, laptop) have internet on the same network.
-
If the net is down, restart the router (unplug for 1–3 minutes, then power it back on).
-
After the router comes back online, restart the LG TV (turn off, unplug for 60 seconds, then plug back in).
Try launching YouTube again; if the code goes away, the problem was temporary network instability.
2. Update or reinstall the YouTube app
Outdated or broken app files are a leading cause of Error 137.
-
Press Home on the remote → open LG Content Store (or Apps / More Apps).
-
Go to Apps → My Apps → select YouTube.
-
If an Update button appears, tap it and let the update complete.
-
If the error still shows, uninstall YouTube, then reinstall it fresh from the Content Store.
After reinstalling, open YouTube; in many cases, the 137 error disappears because the new install replaces the crashed or corrupted app.
3. Clear YouTube cache and app data
Corrupted cache or app data can also trigger Error 137.
-
Press Home → Settings → General → System settings → Application manager.
-
Select YouTube → choose Clear cache (and Clear data if available).
-
Exit the menu and launch YouTube again.
If the YouTube app opens normally, the issue was confined to the app’s local storage.
4. Verify date, time, and location settings
Incorrect date/time or mismatched location can confuse streaming services and cause app crashes.
-
Go to Settings → General → Date & Time and set to Automatic (Synchronize with network). If that fails, set the correct time and date manually.
-
In Settings → General → Location, confirm your country is correctly selected.
Test YouTube again; proper date/time and location often stop the app from throwing code 137.
5. If YouTube still shows Error 137
-
Try connecting the TV to the router via Ethernet cable instead of Wi‑Fi to rule out wireless issues.
-
If all app‑level fixes fail, a factory reset can clear deeper software corruption, but this will erase all apps, accounts, and settings.
If the YouTube app still crashes with Error 137 after a reset and updated webOS/firmware, the fault may lie in the TV’s main board or webOS partition, and it’s best handled by a technician (such as Pro‑Logic Technologies) who can test hardware and firmware more deeply.
