Streaming Not Working on LG TV? Here's How to Fix It

If an app won't open, keeps buffering, or shows a black screen on your LG Smart TV, the fastest fix is almost always the same: unplug the TV at the wall for 60 seconds (a true power-drain reset, not standby), then check for a webOS update under Settings → Support → Software Update. Below are the exact LG webOS steps for each common problem, by symptom, so you can jump straight to yours.

Common streaming problems on LG Smart TV — and the exact fix

Netflix / Disney+ / app won't open on LG TV — App closes to the home bar or hangs on its splash screen

Why: Corrupt cached app data after a webOS or app update.

Fix:
  1. Settings (gear) → General → Home/Apps → find the app → Delete, then re-install it from the LG Content Store.
  2. Unplug the TV at the wall for 60 seconds (power-drain reset), then plug back in.
  3. Settings → Support → Software Update → Check for updates to pull the latest webOS.
  4. If only one app fails, sign out inside that app, reset the TV, then sign back in.

LG TV keeps buffering / low video quality — Spinning wheel mid-stream or stuck at SD

Why: Weak Wi-Fi to the TV or an overloaded webOS memory cache.

Fix:
  1. Settings → Connection → Wi-Fi Connection → check signal strength; switch to the 5 GHz band if available.
  2. Close background apps: press and hold Home, then swipe up to close recent apps.
  3. For 4K/HDR content use a wired Ethernet connection into the TV if you have one.
  4. Restart the router: unplug 30 seconds, plug back in, then reconnect the TV.

LG TV black screen / no picture (audio only) — Sound plays but the screen stays black

Why: HDCP/display handshake or an app rendering glitch in webOS.

Fix:
  1. Press Home to exit the app, then relaunch it — this clears most black-screen glitches.
  2. Power-drain reset: unplug the TV for 60 seconds.
  3. Settings → Picture → turn off Energy Saving / ambient dimming temporarily to rule it out.
  4. If using an external device (soundbar/receiver), connect the source directly to the TV to test HDCP.

LG TV won't connect to Wi-Fi — 'No network' or apps say you're offline

Why: Stale DNS or network settings stored in webOS.

Fix:
  1. Settings → Connection → Wi-Fi Connection → Other Network → re-enter your password.
  2. Set DNS manually to 8.8.8.8 under Advanced Wi-Fi settings if auto-DNS fails.
  3. Power-drain reset the TV and restart the router together.
  4. As a last resort: Settings → General → Reset to Initial Settings, then set up Wi-Fi fresh.

Universal LG fix: the 60-second power-drain reset that clears most issues

  1. Unplug the TV at the wall for a full 60 seconds — standby does not clear the memory; the power drain does.
  2. Keep webOS updated: Settings → Support → Software Update → Automatic Update on.
  3. Delete and re-install any single app that misbehaves before resetting the whole TV.

FAQ

Why do all my streaming apps suddenly stop working on my LG TV?

Usually a webOS memory issue or a dropped Wi-Fi connection. A 60-second power-drain reset plus a router restart fixes the majority of cases. If only one app fails, delete and re-install just that app.

How do I update apps on an LG Smart TV?

Open the LG Content Store → My Apps; updates install automatically when the TV has internet. To force the latest webOS, go to Settings → Support → Software Update → Check for updates.

My older LG TV no longer supports Netflix — why?

LG TVs from roughly 2017 and earlier are being dropped from app support as webOS requirements rise. If the app is gone from the Content Store, the device is no longer supported and a cheap external stick is the fix.
