Samsung TV Error 001: How to Fix Smart Hub Setup
Error 001 (also shown as Error_exe_001 or 0-1) is a Smart Hub error: your Samsung TV can't load the country-specific app list or terms because the region isn't set correctly or the TV has no working internet. It's a setup issue, not a broken panel.
SamsungSamsung TV Error Code 102: How to Fix This Network Error
Error 102 is a network connection failure: your Samsung TV could not connect to the wireless network or reach the Smart Hub servers. It's usually fixed on the network side (router, password, Wi-Fi band or DNS), not by repairing the TV.
SamsungSamsung TV Says Mode Not Supported: How to Fix It

SamsungSamsung TV Remote Not Working? Batteries, Pairing and Reset
Samsung splits a remote that stops working into simple causes you can fix yourself (flat batteries, a lost connection with the TV, dirty buttons, a software glitch, a button that only works in some modes) and technical faults for a service center (a damaged remote or a faulty remote sensor in the TV). For a Bluetooth remote that keeps losing the connection, Samsung adds removing the case, re-pairing and a remote reset.
SamsungSamsung Smart Hub Not Working or Not Loading? How to Fix It
Samsung groups several symptoms under Smart Hub not working: Smart TV won't start or freezes, a black screen appears in its place, it keeps loading, or apps won't open or are missing. Samsung's steps are a full restart, Home Mode, the network connection and DNS, a software update, and finally a Smart Hub reset or a factory reset. Samsung Russia also warns that Smart Hub can be unavailable or unstable in some regions because of local network restrictions.
SamsungSamsung TV App Won't Install or Open? Error 52028 and What to Try
Samsung's support pages treat an app that is freezing, not loading, missing or crashing with the same sequence: cold boot the TV, update its software, delete and reinstall the app, and reset Smart Hub last. Samsung Russia adds testing another Wi-Fi network, changing the DNS server and, when the TV runs out of memory, installing apps on a USB drive. The Samsung help pages used for this guide do not explain codes 52028 or 102028.
SamsungSamsung TV Lines on Screen: Horizontal or Vertical Lines Fix
Lines on a Samsung TV screen come either from the signal (the input, the cable or the connected device) or from the TV itself. Samsung's own troubleshooting separates the two: see whether the lines move, reconnect the cable, check the TV menu and run the Picture Test.
SamsungSamsung TV Has Sound but No Picture: Fix the Black Screen
When a Samsung TV plays sound over a black screen, Samsung's own troubleshooting starts with the Home button. If the menu appears, the TV is on and the fault sits in the source, the cable or the connected device. If the menu stays black too, the TV may have a power problem and need service.
SamsungSamsung TV Keeps Turning Off by Itself? Timers, Anynet+ and Power
Samsung names two main reasons a TV switches itself off: a connected device has powered off, or the TV's own settings are doing it. A standby light that flashes as the TV shuts down means a fault that needs repair. Otherwise Samsung's steps cover the power cord, timers and power saving, Anynet+ (HDMI-CEC), Power On with Mobile, connections, the remote and a software update.
SamsungSamsung TV Turns On by Itself? Check the Event Log and Anynet+
Samsung links a TV that turns on by itself to the remote, connected devices or settings such as HDMI-CEC. On 2019 and newer models the Event Log under About TV records why the TV powered on, so you can switch off the exact app, device or feature that woke it.
SamsungSamsung TV Won't Play Videos from USB? Codecs, AVI and File System
Samsung says every TV has its own requirements for video files: file format, video codec, resolution and more. If the file doesn't match all of them, the TV won't play it. TVs from 2018 (N series) onward don't play DivX/Xvid, a codec common in .AVI files. If the file matches and still won't play, Samsung's steps are a restart, another USB port or flash drive, a supported file system (FAT32, NTFS or exFAT), a software update, a factory reset and, last, a service centre.
SamsungSamsung TV Not Connecting to Wi-Fi? Router, Hotspot and Reset Fixes
Samsung separates this problem into a TV that doesn't see your Wi-Fi, one that won't connect, and one that connects but keeps losing the signal. Its steps start with restarting the TV and router from the wall and checking other devices, use a phone hotspot to tell a router problem from a TV problem, and then move to router settings, a manual DNS, a network reset, a software update and, last, a factory reset.
SamsungSamsung TV Won't Turn On? What the Red Standby Light Tells You
When a Samsung TV won't turn on, the small red standby light tells you where to look. Samsung splits its troubleshooting into three cases: the light is on, off, or blinking. The first fixes are unplugging the TV for 30 seconds and moving it to an outlet you know works, without a surge protector. A light that keeps blinking after that is Samsung's signal to request service.
SamsungSamsung TV Won't Update or Shows Error 800? Update It by USB
A Samsung TV can update its software over the internet or from a USB flash drive. An internet update needs a Smart TV, a working connection and, on 2023 and newer models, a Samsung account sign-in. If Software Update is unavailable, Samsung's fix is to unplug the TV for 5 minutes. If the TV still can't download the update, Samsung's alternative is the USB method with a FAT32 flash drive.
SamsungSamsung TV Narrating Everything? How to Turn Off Voice Guide
When a Samsung TV announces everything you do, Voice Guide is on. Samsung describes it as an accessibility function for people who are blind or have low vision, and says it typically gets turned on by accident when someone holds the volume button on the remote. You can switch it off from the Accessibility Shortcuts menu or under Settings → Accessibility; the path depends on the model series.

SamsungSamsung TV Says No Signal on HDMI: How to Fix It
"No Signal" means your Samsung TV isn't receiving video on the input you selected. It doesn't mean the TV is broken. Nearly every case comes down to the wrong source, a loose or bad HDMI cable, a device that isn't sending a picture, or (on One Connect models) the box between the TV and your gear.
SamsungSamsung TV: No Sound Through HDMI ARC or eARC Soundbar
When a soundbar or AV receiver connected over HDMI ARC/eARC goes silent on a Samsung TV, the cause is almost always the handshake: wrong port, soundbar not on D.IN, Anynet+ (HDMI-CEC) off, Sound Output not set to Receiver (HDMI), or an eARC/cable mismatch.
Frequently asked questions

Settings → General (or Connection) → Network → Reset Network. This clears saved Wi-Fi and network settings without deleting your installed apps.
