LG TV Error 137 keeps recurring after basic fixes when the underlying cause is not just a temporary app crash or bad Wi‑Fi, but something deeper in the network, software, or hardware side of the system. This code, which appears on the YouTube app, usually means the TV cannot establish a stable streaming session to YouTube’s servers, so the app fails and throws the same message every time you open it.
1. Persistent network or DNS instability
Even if your internet looks “working,” inconsistent speed, packet loss, or a misconfigured DNS can cause Error 137 to reappear:
-
Weak or unstable Wi‑Fi: If the TV frequently drops packets or fluctuates between slow and fast, YouTube may fail to stream and keep showing 137 after every restart.
-
Router or DNS glitches: Some routers and local DNS servers misroute or block large‑video traffic, especially during peak times, making the YouTube session unstable even though other apps seem fine.
If you’ve tried restarting the router and TV several times without success, this is a sign the network path itself is unreliable, not just a one‑off glitch.
2. Outdated webOS firmware or incompatible app builds
Error 137 can persist after app updates and cache clears if the TV is running an older webOS firmware that has a bug in how it handles YouTube or other streaming apps.
-
LG frequently releases firmware updates that patch YouTube‑related crashes and compatibility issues.
-
If the TV is on an old firmware, reinstalling the YouTube app only refreshes the app on a broken platform, so the same code returns after a few launches.
In this case, the fix is not more app tinkering, but a firmware update (via USB or over‑the‑air) to bring the platform to a stable version.
3. Corrupted internal storage or system files
Smart TVs store apps, cache, and temporary data in internal flash, and if that storage develops bad sectors or corruption, even a factory reset may not fully clean the system.
-
After a reset, YouTube may reinstall but still crash with 137 because the file‑system or webOS partition is partially damaged.
-
This often shows as other apps crashing or the TV behaving sluggishly across the board, not just YouTube.
When this happens, the TV needs a firmware‑based recovery or board‑level intervention to replace or re‑flash the affected storage chip or main board, which is beyond normal user‑level fixes.
4. Hardware‑related issues (Wi‑Fi module or main board)
If network‑ and software‑level fixes have been tried multiple times and Error 137 still returns, the fault may be hardware‑related:
-
A failing Wi‑Fi module can cause the TV to connect to the router but drop or distort data, repeatedly breaking YouTube’s connection.
-
A weak or marginal main board (including the processor or memory managing webOS) can repeatedly crash the YouTube app, especially under streaming load.
In these cases, the problem is not configuration; it is a physical component that needs inspection and replacement by a technician.
5. How to know when it’s time to call a technician
-
If you’ve done:
-
Power‑cycle and router‑restart.
-
Reinstallation and cache‑clear of YouTube.
-
Firmware update and/or factory reset.
-
…and Error 137 still appears every time you open YouTube, the issue is likely deeper than settings or a single app glitch. At that point, the safest move is to contact LG support or a qualified service provider (like Pro‑Logic Technologies) who can:
-
Test Wi‑Fi signal quality, router behavior, and DNS.
-
Deep‑check webOS firmware and internal storage health.
-
Inspect the main board and Wi‑Fi module if needed.
Persisting Error 137 usually signals that the problem is structural (network, firmware, or hardware) rather than random; addressing those layers systematically is what stops the code from coming back again and again.
