It happens to everyone. You’re settled in for a binge-watch session, but your smart TV decides to act like a brick. Maybe the Netflix app keeps crashing, or the Wi-Fi refuses to connect despite your router sitting two feet away. Sometimes, the software just gets bloated and sluggish. Honestly, the only real fix is a total wipe.
Learning how to factory reset TV is basically the "have you tried turning it off and on again" of the 2020s, but on steroids. It’s the nuclear option. It wipes your apps, your saved passwords, and your carefully calibrated picture settings. But man, does it make everything snappy again.
Why Your TV Actually Needs a Reset
Most people think a factory reset is just for when you’re selling the thing on Facebook Marketplace. Sure, you don't want a stranger in another zip code using your Hulu account. But it's deeper than that. Modern TVs like LG’s C3 OLED or the Samsung S90C are essentially giant smartphones hanging on your wall. They run complex operating systems—webOS, Tizen, or Google TV—and those systems get messy.
Cache files pile up. Firmware updates occasionally install sideways.
If you notice a weird lag when switching inputs or if your screen stays black while the audio plays, a reset is usually the cure. It forces the hardware to reload the original system image, clearing out the digital cobwebs that have been slowing down your processor since 2022.
How to Factory Reset TV: The Big Brands
Every manufacturer hides the reset button in a different sub-menu. It's annoying. You'd think they'd make it easy, but they usually bury it three layers deep to prevent kids from accidentally nuking the whole setup.

Samsung Smart TVs (Tizen OS)
Samsung likes to change their UI every couple of years. If you have a newer model (2020–2025), hit the Home button. Go to Settings, then All Settings. Look for General & Privacy. Inside there, you’ll find Reset.
You'll need a PIN. If you never set one, it’s probably 0000. If that doesn't work, try 1111 or 1234. If you changed it and forgot it, you're in for a fun call with Samsung support, though some models let you reset the PIN via a specific remote button combo (Mute > 8 > 2 > 4 > Power).
LG TVs (webOS)
LG is actually pretty straightforward. Grab the Magic Remote. Hit the Gear icon. Go to All Settings. Navigate to General. From there, you're looking for System, then Reset to Initial Settings.
Everything goes. Your LG account, your calibrated "Filmmaker Mode," and even the channel list if you use an antenna. It’s a clean slate.
Sony and TCL (Google TV / Android TV)
Google TV is the most common OS now. It’s on Sony Bravias, newer TCLs, and Hisense sets.

- Use the remote to go to your Profile Icon or the Settings cog in the top right.
- Select System.
- Go to About.
- Click Reset.
- Choose Factory Reset.
Then, you wait. The TV will likely reboot twice. Don't touch it. Don't unplug it. If you lose power during this process, you might actually brick the motherboard, and then you're looking at a $400 repair bill or a trip to the recycling center.
Resetting Without a Remote
This is the nightmare scenario. You lost the remote in a move, or the dog chewed it, and now the TV is stuck in a boot loop. You can still do this.
Look at the back or the bottom of the TV frame. Most modern sets have a tiny physical button. Sometimes it’s just one button that acts as a joystick. On some Sony models, you can perform a "Forced Factory Reset" by holding the physical Power and Volume Down buttons on the TV unit itself while plugging the power cord back into the wall. You hold them until the LED light turns green.
It’s tactile. It’s a bit clunky. But it works when the software is too broken to navigate with a screen.
The "Soft" Reset Alternative
Wait. Before you go full scorched-earth, try a cold boot. This isn't a factory reset, but it solves 80% of "glitchy" behavior without deleting your apps.

While the TV is ON, hold the power button on your remote. Keep holding it. Don't let go when the screen goes black. Keep holding until you see the manufacturer's logo (like the Samsung or Sony splash screen) reappear. This flushes the RAM. In many cases, the TV will start behaving perfectly after this, and you won't have to spend twenty minutes re-typing your 24-character Wi-Fi password.
What Happens Next?
Once the reset is finished, your TV will act like it just came out of the box. You’ll have to go through the whole "Select Your Language" and "Connect to Wi-Fi" dance.
Pro Tip: Take photos of your picture settings before you reset. If you spent hours tweaking the brightness, contrast, and motion smoothing (or turning it off, hopefully), those numbers are gone once you hit "Confirm Reset." A quick snap with your phone saves you a lot of headache later.
Critical Checklist for a Successful Reset
- Check for Firmware Updates First: Sometimes the bug you’re fighting is already fixed in a new patch. Check the "Software Update" menu before wiping everything.
- Unplug External Devices: Disconnect your Shield TV, Apple TV, or Xbox before resetting. Sometimes HDMI-CEC (the thing that lets your remote control multiple devices) can interfere with the reset process.
- Sign Out of Subscriptions: While most TVs wipe everything, it’s good practice to go to your Netflix or Amazon account on a computer and "Sign out of all devices" after the reset just to keep your account security tight.
- Ethernet is Better: When setting the TV back up, plug in an Ethernet cable if you can. It makes the initial "Terms and Conditions" and app downloads go five times faster than using Wi-Fi.
Don't be afraid to pull the trigger on a factory reset. It’s a tool. If your smart TV feels more like a "dumb" TV because it's lagging, a reset is the most effective way to reclaim the performance you actually paid for.
Start by trying the "Soft Reset" (holding the power button). If the lag persists or apps keep crashing, move to the System menu and perform the full wipe. Just make sure you have your streaming logins handy because you’ll be typing them in for the next ten minutes once the TV reboots.
