LG TV Keeps Turning OFF (Learn How To Fix It Quickly)

Having your LG TV keep turning off can be incredibly frustrating to deal with, especially if the cause of the problem isn’t readily apparent! You might be at a loss on where to begin troubleshooting the issue, but LG TV shutdowns aren’t as random as you might expect.

An LG TV can keep shutting off for several different reasons, with the examples below among the most common culprits.

    1. Compromised Power Supply.
    2. Auto Power Off Feature is enabled.
    3. You (or someone in your home) left an active timer on your television.
    4. Bloating Browsing or App Caches.

If you’ve checked for and addressed every possibility above, your LG TV likely has a more serious issue such as defective components or malware infection. In any case, a problem that persists to this point is best left to the care of LG’s robust support network.

Technical glitches on your LG TV are infuriating disruptions that ruin the little time you have to relax, so it’s something you’ll want to deal with soon. Fortunately, it can be solved in as little as half an hour if you follow the troubleshooting guidelines provided below.

What to Do if My LG TV Keep Turning Off Randomly?

Ensure your Power Supply Isn’t Compromised

The first thing you need to check for is your TV’s power supply.

Is there any noticeable damage to the power cable? Are there any knots, twists, or visible wiring? Does it seem stretched, old, or noticeably worn down? If your answer is yes to any of the above, the problem may lie with your power cable.

There’s also a chance that your cable is perfectly fine, and the problem actually stems from a loose or faulty wall socket. If your LG TV keeps shutting off even with a pristine cable, try plugging it into a different wall socket and see if that makes a difference.

The good news is that power supply problems often prove simple to consistently diagnose and address. If your LG TV frequently shuts off within a very short timeframe, the first thing you’ll want to do is check if your power supply is stable.

Disable the Auto Power Off Feature

Most televisions come with an inactivity timer – for LG TVs, this setting is called “Auto Power Off”. By default, LG TVs automatically shut off after four hours of inactivity, though this can be changed to anywhere between fifteen minutes to eight hours (depending on the model!).

The default Auto Power Off time window of four hours is pretty generous, and typically won’t be an issue unless you’re binging a long series through the night. If you want to disable or at least modify the Auto Power Off feature, simply follow the video guideline provided.

If your LG TV keeps turning off in the middle of a watch session, you’ll want to ensure that the Auto Power Off setting is either disabled or set to the maximum available duration.

Check for Timers Someone Else Might Have Set

There’s a slim possibility that someone in your household set a sleep timer on your television without letting you know, which could be the reason why your LG TV keeps shutting off!

Clear Browsing and App Caches

Lastly, your LG TV might be turning off and underperforming because it’s being throttled by bloated data. This can come from either browser data caches (and cookies) or app caches, which serve as temporary storage for content the app needs quick access to! It’s creating a “shortcut” by keeping this data on standby, which can accumulate and rapidly get out of hand.

Once properly cleared, your television’s performance should dramatically improve.

Here’s how you can clear cookies and browsing data on your LG TV!

If you don’t have time to check the video out, here’s a quick rundown of what you have to do.

    1. Launch your browser of choice on your smart TV.
    2. Access the menu on the upper right side, then go to “Settings”.
    3. Keep scrolling until you see “Clear Browsing Data”, then delete accordingly.
      • Clearing all browsing data is more effective at improving your LG TV’s performance than removing cookies, but will sign you out of any active accounts!

Certain complex applications such as Netflix or Amazon Prime can produce a ton of cache files, taking up a significant degree of your LG TV’s limited storage space. The worst part here is that it won’t even be obvious at first – you’ll only be able to tell by seeing performance taking a drastic hit or if you manually check the app’s total data cache! Here’s how you can wipe it!

Another tip: If you can’t clear your app’s data cache from the settings menu (or your LG TV can’t perform the task for whatever reason) uninstalling and reinstalling the app will have the same effect and thoroughly clear out temporary cache files.
