Netflix Error ui-800-3 (307007) explains the provider’s code meaning and the safest first checks. Keep every suffix or number visible, because similar codes can mean different things.
Confirm the exact device and platform. Use low-risk checks first. App availability, firmware version and root cause are not assumed from a brand or series name.

Provider may have platform-specific instructions.
Confirm the exact message
- Record the provider name and the full code exactly as displayed: ui-800-3 (307007).
- Keep leading zeroes, decimal points, and any number in parentheses. A similar-looking code can have a different meaning.
- Check whether the issue is on the TV's built-in app or an HDMI streaming device; their menus differ.
Work through the provider-backed checks
Restart TV/device via Settings if available Reversible
- Use the TV’s Restart control, not only sleep/standby.
- After the TV restarts, open the app again.
Contact streaming app provider support Information check
- Record the exact error including parentheses, TV model, OS, app version and date.
- Use the service’s official help center.
- Do not share passwords or account verification codes with TVFix.
Similar codes with different details
Use the exact code shown on your screen; these variants should not be silently merged.
If it still fails
Use the linked provider help for the exact code. For a device hardware or firmware warning, contact the device maker before a factory reset. Keep app, TV and network support roles separate.
When to get more help
If the issue persists after the safe checks, use the TV maker for power, display and system faults; the app provider for a single app or account; and the internet provider for a network-wide outage. An app or model-specific compatibility decision needs the exact SKU and a current official source.
