1003
LG Smart TV
Severity: MinorWhat Does This Error Mean?
LG webOS error 1003 means the TV could not sign into your LG account — the credentials were rejected, the account is locked, or the region setting on the TV does not match your account region.
The TV still works for HDMI inputs and basic features.
Logging in from your phone or computer to verify credentials, then re-entering on the TV, clears most cases.
Affected Models
- LG OLED C series
- LG OLED B series
- LG QNED series
- LG NanoCell series
- LG webOS UHD models
Common Causes
- Wrong password
- Account email mistyped
- Account locked from too many wrong-password attempts
- Region setting on TV does not match account region
- Two-factor authentication blocking the TV
- LG account server brief outage
How to Fix It
-
Verify credentials on a phone.
Open lgaccount.com on a phone or computer.
Sign in with the same email and password you tried on the TV.
If that succeeds, the credentials are correct and the issue is on the TV side.
If that fails too, fix the password first. -
Reset the password if needed.
Click Forgot Password on the LG account page.
Follow the email link.
Set a new password.
Try the new password on the TV. -
Check region setting.
Settings → All Settings → General → Location → LG Service Country.
Set this to match the country where your LG account was created.
Mismatched regions make sign-in fail with error 1003. -
Disable 2FA temporarily.
If you have two-factor authentication on your LG account, the TV may not handle the prompt well.
Sign in to lgaccount.com, disable 2FA briefly, sign into the TV, then re-enable 2FA after.
Re-signing the TV usually only needs to happen once. -
Reboot the TV.
Unplug for 60 seconds.
Plug back in.
Try login again.
Cached state from a previous failed login can persist until reboot. -
Update firmware.
Settings → All Settings → General → About This TV → Software update.
Apply pending updates.
Account handling has been improved across webOS versions. -
Wait if servers are down.
If multiple users report the same error in your region, LG account servers are likely having issues.
Try again in 30-60 minutes.
The error clears on its own once service is restored.
Frequently Asked Questions
Do I need an LG account to use the TV?
No — the TV works fine for HDMI sources, broadcast channels, and most apps that use their own accounts (Netflix, YouTube, etc.).
The LG account is only needed for LG Content Store and a few LG-branded features.
Skip if you do not need them.
