The hidden Samsung TV service mode unlocks powerful tools: factory reset, hotel mode on/off, parental controls, and picture/sound calibration. This guide shows you 6 remote-control codes to open the service menu, how to reset without a PIN, and the precautions to take first.

Find your model below and try the codes in order until the menu opens.
What Is the Samsung TV Service Mode?
The service mode is a hidden engineer's menu Samsung builds into every TV. From it you can run a factory reset, enable or disable hotel mode, manage parental controls, fine-tune picture and sound calibration, and check panel information. The valuable functions for users are the factory reset and the hotel-mode toggle.
For the general explanation of what the service menu is and how technicians use it, see our guide to what the TV service menu is.
Important Warnings Before You Enter
Read this first: photograph every screen before you change any value. Wrong internal settings can break the picture or sound seriously. Change one value at a time, never blindly. The factory-reset option itself is safe — random value changes are not.
6 Codes to Open the Service Menu
You'll need the standard Samsung IR remote (smart/Bluetooth remotes often can't send these sequences). Put the TV in standby first for most methods, and press the keys briskly — slow entry won't register. Try the methods one by one until the menu appears.
Info – Menu – Mute – Power
A widely used code. In standby, press Info → Menu → Mute → Power. The TV starts automatically and the service menu opens.
Mute – 1 – 8 – 2 – Power
Turn the TV off, then press Mute → 1 → 8 → 2 → Power. Works on many older and mid-range models.
Display – P.STD – Mute – Power
In standby, press Display → P.STD → Mute → Power (P.STD is the Picture Standard button on some remotes).
Sleep – P.STD – Mute – Power
In standby, press Sleep → P.STD → Mute → Power. Try this one if the previous method doesn't respond on your model.
Display – Menu – Mute – Power
In standby, press Display → Menu → Mute → Power.
Mute – 1 – 1 – 9 – Enter (TV On)
With the TV turned on (not standby), press Mute → 1 → 1 → 9 → Enter/OK within 3 seconds. This works most often on newer Samsung models (2021 and later).
Once inside, navigate with the arrow keys; Enter selects and Return/Exit saves and leaves. You'll find Factory Reset, Hotel Mode on/off, and display and sound settings.
Which Code to Try First on Your Samsung Model
The right code depends on the age of the set. For pre-2012 CRT and early LCD models, Display – P.STD – Mute – Power is the classic one. For most 2012–2016 LED/LCD sets, Mute – 1 – 8 – 2 – Power works on the widest range of chassis — try this one first. For 2017 and newer smart TVs, use the TV-on variant Mute – 1 – 1 – 9 – Enter. Two practical points: press the keys quickly, within about three seconds, with the TV in the required state (off or on, as listed); and use the original Samsung IR remote — many universal remotes cannot send the key sequence fast enough, which is a common reason a correct code appears to fail.
Factory Reset From the Service Menu
Inside the service menu, look for Factory Reset / Reset, select it, and confirm. The TV reboots with all default settings. Before you reset: photograph or write down your current settings — if a service-menu value was already wrong, you'll need your notes afterward. This reset also disables hotel mode, returning the TV to normal operation.
After the Service-Menu Reset: What to Reconfigure First
A service-menu factory reset runs deeper than a normal settings reset: it clears tuner data, hospitality settings, and calibration tables. After the TV reboots, re-run the channel auto-program first, then check the country/region setting — a wrong region can silently lock tuning to the wrong broadcast standard. Re-enable HDMI-CEC (Anynet+) and re-enter your Wi-Fi password. If the picture looks off, the reset restored the factory white-balance values, so resist the urge to open the ADC/WB submenus — the defaults are correct for an unmodified panel. One warning: never change Option Bytes or ADC values to "experiment"; a wrong value there can blank the screen entirely, and only your earlier photos will get it back.
Samsung TV Reset Without PIN
Forgot your Samsung security PIN? You can still reset to defaults:
- Put the TV in standby mode (red standby light on).
- Point the original remote at the TV's IR sensor and press Mute → 8 → 2 → 4 → Power steadily.
- The factory reset process begins automatically — wait 1–2 minutes without unplugging.
- The TV turns on with the setup screen — complete the initial setup.
The default Samsung PIN is 0000 — if you never changed it, you can also reset through Settings → Support → Self Diagnosis → Reset. For more PIN solutions, see our TV PIN reset guide.
When 0000 Doesn't Work: Samsung PIN Alternatives
If 0000 fails, the PIN was changed — by a previous owner, a dealer, or a hotel lock. Try the common dealer defaults in order: 1111, 1234, then 4321. On older Samsung models there is a dedicated PIN-clear sequence: with the TV on, press Mute – 8 – 2 – 4 – Power, which forces the PIN back to 0000. If the set was hotel-locked, the PIN field may reject everything until the hospitality/hotel mode is cleared from the service menu first. When every PIN fails, the service-menu factory reset in section 4 bypasses the PIN entirely — use that route instead of guessing.
Exiting the Service Menu & Troubleshooting
Press Exit or Return to leave — confirmed changes are saved. To discard unsaved changes, just turn the TV off and back on. Don't unplug the TV while the service menu is open.
- Service menu won't open: use the original Samsung IR remote, enter sequences briskly in true standby. On very new models some older codes are blocked — Method 6 (TV on) is a good option to try.
- TV stuck after a change: power off and on — unsaved changes are discarded. If a saved change broke the picture, re-enter service mode and restore your photographed values.
- TV stuck on logo after reset: wait up to 10 minutes for the first boot. If it persists, the firmware may be corrupted — see our LED TV firmware loading guide.

Frequently Asked Questions
What is the Samsung TV service menu code?
The widely used standby code is in the 6 Codes section above, with the TV-on alternative there too.
Will a factory reset remove hotel mode?
Yes — the service-menu factory reset disables hotel mode and restores normal operation.
What is the default Samsung TV PIN?
0000. If you changed it and forgot it, use the Mute-8-2-4-Power reset method.
Is it safe to change values in the service menu?
Only if you photograph the originals first and change one value at a time. Wrong values can cause serious picture or sound faults. The factory reset option itself is safe.
Try the codes in order, with the TV in the state each one requires, and photograph every original value before changing anything. If you have no remote at all, our Samsung service menu without a remote guide covers the panel-button route instead.
