Alas, old men! When I first entered the industry, I turned around three times to the LED display but couldn't find where the boot button was. I was not afraid of jokes when I told it, but I almost dismantled the entire screen at that time. There are so many types of LED screens on the market now, and the position of the boot button is really like playing hide and seek. Let’s talk about this today, so that you can be a “boot button hunter” after reading it!

1. Where is the boot button hidden?

​​Tell me some cold knowledge first​: Last year, a new LED large screen was delayed by 2 hours because the staff could not find the boot button. In fact, the boot button position designs for different scenarios are very different:

• ​​Outdoor advertising large screen​: Usually in​The lower right corner control box​Inside, you have to lift the waterproof cover to see the red button
• ​Transparent video wall​: Now popular integration isSmart central control panel​, you have to find the metal box with fingerprint recognition first
• ​Stage floor tiles screen​: The most hidden! Have to touch the side of the box​Frorod trigger switch​, some need to be activated with magnetic keys

(Suddenly remembered) That’s right! Some high-end screens do not have physical keys at all, so they have to use them.​Mobile APP remotely starts​​. The last time I installed a fence screen in the gymnasium, I encountered this. The worker took the remote control and looked for the switch all over the room, but the result was that he used a Bluetooth connection.

2. How to set up different scenarios?

​​The key point is here​! The boot button is found, how to set it to avoid damage to the device? Remember this "three first three last" formula:

1. ​​Check the power first and then turn on​
   Especially for outdoor screens, it is necessary to confirm that the voltage is stable at 380V±5%. Last year, a billboard burned 12 modules at the moment of power-on operation due to unstable voltage, and the maintenance cost was more than 80,000 yuan.

2. ​Turn on the computer first and then turn on the screen​​
   The control computer must be started 30 seconds in advance, and then press the boot button after the software is loaded. Otherwise, the screen will easily appear, which means plugging in the USB flash drive before the computer is turned on.

3. ​​Switch the brightness first and then display it​
   It is recommended to slowly add the indoor screen from 800cd/m², and do not directly match the outdoor screen to 7500cd/m². Just like the sudden brightest adjustment of the mobile phone screen, it will be dazzling, and the lamp beads are also afraid of "blindness"

To give a real case: the front desk sign screen of a chain store, the clerk always turned off the power supply and caused the motherboard to burn. Later changed to​Intelligent delay shutdown(Press the power off automatically after pressing the shutdown key, the power outage will be automatically delayed by 5 minutes), and the equipment life will be directly extended by 3 years.

3. Don't step on these pitfalls

The three most common places for beginners to fall apart, remember them with a small notebook:

Special reminder that old iron with rental screens is that the aluminum, magnesium, zinc box that can be quickly disassembled and installed must wait after shutting down.​The cooling fan stopsOnly then can the power be unplugged. Last month, a performance team was in a hurry to break the stage, but it burned 18 yuan to receive the card, which hurt the pain.

4. Personal blood and tears experience

After working in the project for so many years, I think it's like finding a boot button, just like falling in love - you have to understand its "temperament". Share three heartfelt words:

1. ​​Read the model than reading the manual​
   Each series of products has design logic: commercial advertising is convenient, stage screen is hidden, and court screen is protective. Remember that the model features are more effective than memorizing the manual

2. ​​Separate solutions must not be missing​
   Many screens are now supportedDual control mode​, such as physical buttons + mobile phone control. The floor tiles for a music festival were designed with NFC induction boot, and the site was stable.

3. ​​Service is more important than technology​
   No matter how good the screen is, it will be in trouble. The key is whether the manufacturer has any24-hour response​. Last time, the stadium screen couldn't be turned on in the middle of the night, and the technical team's video guidance was done in 10 minutes, which is more realistic than any black technology.

Finally, I’ll say it’s heart-to-heart: Don’t force it if you can’t find the boot button! Some high-end screen intelligent systems can automatically diagnose faults, and random pressing will trigger protection locking. Remember, equipment is more delicate than people, we have to follow its "nature".
