Update your TV

There is no standalone software-update guide on this site. Software updates are covered in the firmware section of the reset guide: How to Reset Samsung Smart TV: Complete (Step-by-Step Guide). It explains how to check for updates and install the latest firmware for your model.

How to Cold Boot Your Samsung TV

  1. Turn the TV off — use the remote or the power button on the TV itself.
  2. Unplug the TV from the wall outlet — pull the power cord out of the outlet, not just the back of the TV.
  3. Wait 30 seconds — this lets the TV fully discharge and clear its temporary memory. Don’t rush it.
  4. Plug the TV back in — push the power cord firmly into the wall outlet.
  5. Turn the TV on and wait for the home screen — the OS loads fresh. Test your issue again before trying anything else.

Reset Options — Which One to Use

Reset Type What It Fixes What It Deletes When to Use
Cold Boot (Soft Reset) Temporary glitches, frozen apps, slow menus Nothing First step for any sudden problem
Smart Hub Reset App crashes, missing apps, Smart Hub errors App logins and Smart Hub data Persistent streaming and app problems
Network Reset Wi-Fi failures, saved network errors Saved Wi-Fi networks only Internet connection problems
Sound Reset Incorrect audio output settings Custom sound settings only No sound or wrong audio output
Factory Reset Severe software issues All settings and preferences Last resort — after all else fails
Default PIN for all Samsung resets: 0000 Settings → General → Reset

⚠️ Before You Factory Reset

A factory reset erases all your app logins, saved Wi-Fi passwords, and picture settings. Save your streaming passwords first, then try a Smart Hub reset and a network reset before going to a full factory reset — those two targeted resets solve the majority of severe cases without wiping everything.

Frequently Asked Questions

QHow do I fix a Samsung TV that is not working?
Start with a cold boot, then check the input source, cables, internet connection, app status, and software updates. If the problem affects apps only, reset Smart Hub. If it affects Wi-Fi only, reset network settings. Use factory reset only after simpler fixes fail.
QWhy is my Samsung TV so slow?
Accumulated cached data is the usual cause. Perform a cold boot first (unplug the TV for 30 seconds, then plug it back in). If still slow, see: How to Clear Cache on Samsung TV.
QHow do I reset a Samsung Smart TV?
Cold boot: unplug the TV from the wall outlet for 30 seconds, then plug it back in and turn it on. Smart Hub reset: Settings → Support → Self Diagnosis → Reset Smart Hub (PIN: 0000). Factory reset: Settings → General → Reset (PIN: 0000). Without a remote: Reset Samsung TV Without Remote.
QWhy won’t my Samsung TV connect to Wi-Fi?
Delete the saved network profile and reconnect from scratch. If that fails, go to Settings → General → Network → Reset Network. Also confirm the TV’s date and time are set to automatic — incorrect time settings block secure Wi-Fi authentication on many Samsung models.
QWhat are the best Samsung TV picture settings?
For movies: Movie Mode with Warm2 color temperature and sharpness set low. For gaming: enable Game Mode under Settings → General → External Device Manager. For sports: Standard Mode with Auto Motion Plus set to “Clear.” See the full breakdown: Best Samsung TV Picture Settings.
QWhat does Smart Hub Reset do?
It clears all app data, signs you out of every streaming service, and resets the app ecosystem to its default state. It does not delete general TV settings or your Wi-Fi password. It’s the most effective fix for persistent app crashes and freezing on Samsung Smart TVs.
QHow do I check if my Samsung TV is still under warranty?
Visit How to Check Samsung Warranty Status and enter your TV’s model number and serial number. Find both on the label on the back of the TV or under Settings → Support → About This TV. Standard US warranty is 1 year on parts and labor.
QWhat is the default PIN for Samsung TV reset?
The default PIN for all Samsung TV resets — including Smart Hub Reset and Factory Reset — is 0000. If this doesn’t work, the PIN was changed at some point. Samsung’s support team can assist with PIN recovery.
