What should I do if I forget your LED screen password? Don’t panic! Today we will talk about this headache——​ ​Where is the super password for LED screen hidden​​? As an "old driver" who has been working hard in the display industry for many years, I have seen too many people jumping because of password problems. Don’t worry, after reading this article, you can also become a "password cracking expert"!

1. Understand these basic knowledge first

​​What is the LED screen password? ​ ​
Simply put, it is the "key" that controls the display parameters. Just like your door needs a key to unlock, if you want to change the text, brightness or display mode on the screen, you have to enter this password first. There are two common password types:

• ​​Factory default password​​: The "master key" preset by the manufacturer, such as 168 and 888 auspicious numbers
• ​​Custom password​​: The installation master or the exclusive password you set yourself

​​Why do you forget your password? ​ ​
The most outrageous case I have ever seen: A customer sets his password as his ex-girlfriend's birthday. After breaking up, he wants to change the content of the display screen three years later, but he tried more than 50 dates... So,​ ​Don't use a combination that is easy to forget​​！

2. Three tricks to crack passwords

Tip 1: Try these "universal passwords""

​​List of common default passwords​​(It is recommended to try one by one):

• 168 (The highest appearance rate! )
• 888
• 12345678
• 666
• 20052006 (This is said to be the wedding anniversary of a certain engineer)

👉 ​​Tips​​: Passwords for different brands may vary. For example, outdoor screens of a well-known brand are commonly used for 168, while indoor conference screens may be used for 88888. If the installation master is still there, call and ask!

The trick 2: Restore the control card to factory"

If you have tried all the above passwords, it means that the password may have been changed. At this time, you will be sacrificed​ ​Hardware reset method​​：

1. ​​Find the control card​​: Usually behind the module on the right side of the screen, the "control card" label is attached
2. ​​Press and hold the test key after power off​​: Press and hold the black button for 10 seconds and don’t let go (you have to persist even if your hands are sore! )
3. ​​Power on and set up​​: The password will be restored to 12345678 or 168

⚠️ ​​Important reminder​​: This method will clear all settings! Remember to take pictures of the original screen parameters in advance, otherwise you can't adjust it back to the original state, so don't cry.~

Tip 3: Software Deletion and Reinstallation Technique

Suitable for computer control software to forget password:

1. Uninstall the original control software (remember to check "Delete all configuration files")
2. Go to the official website to download the latest version of the software
3. When you reset the screen parameters, the default password will become 168 or 888 again.

💡 ​​Personal experience​​: Some software is not uninstalled cleanly, so you have to use professional cleaning tools to scan the registry. If you find it troublesome, it is easier to just contact the manufacturer to "reset the toolkit with one click"!

3. Practical tips for anti-password loss

As a person who has experienced it, I have to tell you a few​​Secrets for summarizing blood and tears lessons​​：

• ​​Password memorandum​​: Save a note on your mobile phone and sync it to the cloud disk
• ​​Labeling method​​: Use waterproof stickers to write the password on the back of the control card
• ​​Unified password rules​​: For example, "Company abbreviation + installation date", which is both safe and easy to remember
• ​​Regular inspection system​​: Let operation and maintenance personnel check their passwords every quarter

There was once a customer who did not do these things, and the outdoor large screen was blacked out for 3 days and lost 50,000 yuan in advertising fees every day... Is this lesson profound enough?

4. Black technology that may replace passwords in the future

Some high-end LED screens have been used now​​Biometrics​​Now! for example:

• Fingerprint unlock (never be afraid of forgetting your password again)
• Face recognition (you can change the content of the screen by blinking)
• Dynamic QR code (scan the mobile phone to instantly authorize)

However, these technologies are still in the testing stage. I want to say it​ ​Traditional password + intelligent management​​It is the most reliable combination now. Just like our company's display screen, it not only provides a password manual when it is shipped, but also can be selected.​ ​IoT Password Manager​​, view the modification records at any time through the mobile APP.

Finally, I would like to say: Is the password big or small? Don’t think that “it doesn’t matter if you can reset it anyway”. There are too many lessons to lose the chain at critical moments! Check whether your LED screen password management is in place, don't wait until something goes wrong before regretting it~
