LG TV Error 137 on the YouTube app can be stopped from coming back by treating the root causes—flaky network, outdated software, or app‑data corruption—rather than just reacting to the code each time it appears. Error 137 is YouTube‑specific and typically means the TV cannot maintain a stable connection or launch the app cleanly, so “permanent” prevention is about stabilizing that environment.
1. Lock down a stable network path
A recurring Error 137 is often a sign that the streaming path is simply not reliable enough. To harden it:
-
Use Ethernet instead of Wi‑Fi whenever possible: plug the TV directly into the router via LAN cable so Wi‑Fi dropouts or interference cannot break the YouTube session.
-
Place the router close to the TV or use a Wi‑Fi extender: if Ethernet is not an option, ensure the TV is in a strong‑signal zone and avoid thick walls or metal objects between the TV and router.
-
Switch to a stable DNS: in the TV’s network settings, change DNS to a public service like Google DNS or Cloudflare to avoid ISP‑related quirks that interrupt streaming.
Once the TV has a clean, consistent connection, YouTube rarely hits 137 during normal use.
2. Keep YouTube and webOS up to date
Outdated firmware or app builds are a common reason for recurring crashes.
-
Update the YouTube app regularly:
-
Press Home → LG Content Store → Apps → My Apps → YouTube → check for Update and install it when available.
-
-
Update the TV’s firmware:
-
Go to Settings → All Settings → Support → Software Update → Check Now and install any pending updates.
-
Modern webOS updates often patch YouTube‑specific bugs, so staying on the latest firmware reduces the chance of 137 resurfacing.
3. Maintain a clean app and storage environment
Corrupted cache or full internal storage can cause YouTube to crash repeatedly, even after a reset.
-
Schedule periodic cache clears for YouTube:
-
Home → Settings → General → System settings → Application manager → YouTube → Clear cache (and Clear data if needed).
-
-
Delete unused apps and files to free internal storage.
-
Remove old or rarely used apps, photos, and downloads so the TV is not running low on space.
-
A clean, reasonably empty storage space prevents the system from choking on temporary files and app‑data bloat.
4. Use a “YouTube‑safe” routine after major changes
After big changes (router replacement, new ISP, or firmware updates), YouTube can act up until the TV settles. Create a small routine:
-
Restart the router and the LG TV together once a week if you notice streaming glitches.
-
After any router or internet‑plan change, re‑connect the TV to Wi‑Fi or re‑plug the Ethernet cable and let YouTube initialize once before heavy use.
This keeps the network handshake clean and avoids abrupt disconnects that trigger 137.
5. When hardware may need attention
If you have already:
-
Switched to Ethernet,
-
Updated the firmware and YouTube,
-
Cleared cache and storage,
-
Kept the TV and router on a stable power and signal path,
…and Error 137 keeps returning, the problem may be in the Wi‑Fi module or main board. In that case, only a technician can inspect, re‑flash the firmware, or replace the faulty hardware.
For LG TV owners in Nairobi and other Kenyan regions, pairing good‑practice habits (Ethernet, updates, clean‑app‑routine) with professional help when the code persists is the closest you can get to a permanent fix for LG TV Error 137.
