Do the generic checks first
Before anything below, establish that the television is genuinely the problem. Play the same channel on a phone: if it works there, your subscription and details are fine. Try a second channel: if one fails while others play, that is a single source and nothing on the television will change it.
Our step-by-step troubleshooting guide covers those tests and the layers beneath them properly, and it is the right starting point for any total failure.
What follows applies only once you know the fault sits with this television. It is all specific to webOS.
Quick Start, and why your TV never really restarts
This is the LG-specific one worth knowing before all others.
Most LG sets ship with an instant-on feature enabled — usually called Quick Start or Quick Start+ — which keeps part of the system running while the television appears to be off. It makes the set turn on quickly. It also means that switching off and on again does not clear anything, because the system never actually shut down.
So the standard advice to restart the television is frequently followed and frequently does nothing at all on an LG set. If you have "restarted" and the problem persists, you may not have restarted it.
Two ways to force a genuine cold boot: turn Quick Start off in the general settings and then power cycle, or simply unplug the television at the wall for a minute. Either one clears system memory properly, and a surprising number of app faults disappear at that point.
Which webOS version you have
webOS has changed enormously across generations, and an LG television is only as capable as the version it runs.
Older sets run early webOS versions that current apps may no longer support. LG does not upgrade a television to a newer major version — the version it shipped with is broadly the version it keeps, security patches aside. So an app that requires a recent webOS will not become available by waiting.
Check the version under the general or about section of settings. If it is several generations behind and an app has stopped working or will not install, that is the likely explanation, and it is not something a setting resolves.
Capability within a generation varies too. Memory in particular is limited on lower-specified sets, which shows as a very large channel list loading slowly or an app closing itself.
The app is missing, or will not update
The LG Content Store shows different apps depending on the region set on the television and the LG account signed in, and that catalogue changes over time. An app available last year may not be offered now, and one available in another country may not be offered in yours.
Apps are also withdrawn by their publishers, and older televisions get dropped from support entirely. Neither is a fault you can configure around.
Check whether a suitable alternative exists before concluding the platform is unusable — our guides to IBO Player and Smart IPTV cover the two that dominate this kind of television, and our LG setup guide covers installing and activating them.
Reinstalling properly, and the reset of last resort
webOS gives you a genuine app reinstall, which is the right first move for an app behaving oddly rather than failing outright.
Remove the app from the home row, cold boot the television as described above rather than just switching it off, then install it again. Doing it in that order matters: reinstalling without a genuine restart in between often restores the same broken state.
If that fails, resetting the television to its initial settings is available and is a genuine last resort. It removes installed apps, signs you out of accounts and returns picture and network settings to defaults, so anything tied to the set — including a portal app’s registration — has to be redone. Know what you will need to re-enter before starting, and keep your login details to hand; our guide on backing up your player setup covers what is worth recording.
Network settings on webOS
Two points specific enough to be worth stating.
Portal-based apps identify a television by its network hardware address, and an LG set has a different one for Wi-Fi and for Ethernet. Registering over Wi-Fi and later plugging in a cable can make the app behave as though it has never seen this television. Decide how the set will connect before you register, and stay on it.
Where an app cannot reach its server at all while the rest of the television’s internet works, the network configuration allows a manual DNS entry, and a public resolver is worth trying — our guide on whether changing DNS helps covers when it is genuinely the cause.
For stuttering rather than failure, the connection is almost always responsible. Our buffering guide covers diagnosing it by symptom, and a wired connection does more than any app setting, as our comparison of Ethernet and Wi-Fi explains.
Clock, power settings and things that look like faults
A wrong date or time breaks secure connections, and the symptom is an app that will not connect while everything else on the television works normally. Check that the automatic time setting is on, particularly after the set has been unplugged for a while.
Energy-saving features are the other frequent false alarm. LG sets have an automatic power-off after a period without remote input, and an energy-saving mode that dims the picture. Playback that stops cleanly after the same interval every session is a timer, not a stream problem.
Picture behaviour gets misread too. If live sport looks oddly smooth or artificial, that is the television’s motion processing rather than the stream — our guide on frame rate, motion and judder covers it, and why a picture looks soft covers the rest of the processing settings.
An empty programme guide on first run is usually just an unfinished download rather than a fault; our guide on an EPG that will not load covers when it is genuinely broken.
When webOS is the limit
On an older or lower-specified LG set there is a point past which no setting helps: a very large list that will not load, an app that closes itself, or a store with nothing suitable in it.
A small streaming stick in an HDMI input removes the constraint for a modest one-off cost and keeps receiving updates long after a television platform stops. Our comparison of a Firestick, an Android box and a Smart TV app covers the choice, and whether you need a streaming box covers when it is worth doing.

Frequently asked questions
Why does restarting my LG TV not fix anything?
Because most LG sets ship with an instant-on feature enabled that keeps part of the system running while the television appears off. Switching off and on does not clear memory. Turn Quick Start off and power cycle, or unplug at the wall for a minute.
How do I properly reinstall an IPTV app on webOS?
Remove the app, then cold boot the television — unplugging it or disabling Quick Start first — and install it again. Reinstalling without a genuine restart in between often restores the same broken state.
Why is the IPTV app missing from my LG Content Store?
The store shows different apps by region and by the LG account signed in, and the catalogue changes over time. Apps are also withdrawn by publishers, and older televisions get dropped from support.
Will my LG TV get a newer webOS version?
Generally no. LG does not upgrade a set to a newer major version, so the version it shipped with is broadly what it keeps. An app requiring a recent webOS will not become available by waiting.
My LG TV turns off on its own during a match. Why?
Almost certainly the automatic power-off that triggers after a period without remote input, rather than anything to do with the stream. If it happens after the same interval each time, that is the giveaway.
