With the continuous acceleration of the development of enterprises and the continuous acceleration of the deployment of information equipment, LCD splicing screens are increasingly used in various industries. As a representative of thinner and narrower LCD splicing screens, wider viewing angles and higher quietness, DID LCD splicing screens have also been widely promoted in the market. Therefore, it is used in security monitoring and information disclosure systems in all walks of life. Liquid crystal displays belong to the category of trade leasing, such as the deployment of performance setting equipment. Next, we will analyze and provide DID LCD splicing screens to solve the common obstacles when using DID LCD splicing screens.
1. The essentials for removing common external obstructive signs of DID LCD splicing screen
1. Low power, black screen:
(1) When the above signs appear on the machine, first check whether the power plug, socket, and wiring are loose, and whether the switch (OSD button or remote control) is in the on state;
(2) If the machine is equipped with a timer, you need to check whether the timer red indicator and the green indicator light up at the same time. If only the red indicator light is on and the green indicator light is off, it is probably a clock setting problem, just clock setting Accurate, (please refer to the usage explanation book for details) Obstacles can be removed;
(3) If the machine has a software timing function, check whether the clock setting in the software is accurate (please see the usage explanation book for details).
2. There is no sound
Check whether the sound is set to the minimum or silent mode, and reset the volume mode. (For details, please refer to the usage statement)
If it is offline, if there is no sound, first check whether the external sound line is damaged and whether the connection is accurate.
3. Don't read CF card
The creation of documents in the CF card is strictly prohibited, and the LOOP document is re-created; if the encryption is dull, you need to encrypt the confession (for details, please refer to the use statement)
4. If the above-mentioned methods can not remove your obstruction, please refer to the internal obstruction sign removal method, see 2.
2. The essentials for clearing common internal obstructive signs of DID LCD splicing screen:
1. Low power (black screen): Probably the built-in power supply is bad or the internal drive board is bad; troubleshooting essentials: check whether the power output is normal, if there is no power output, you can confirm that the power supply is bad, if the power output is normal, it may be a bad drive board .
2. Fuzzy screen: the appearance of non-stop performance in a certain area on the LCD screen or the performance is very called fuzzy screen; troubleshooting essentials: check whether the signal transmission line inserted on the LCD screen is loose and other signs that cause bad warfare, if this environment occurs The signal line is inserted tightly and firmly, and check whether the problem is handled; if there is no such environment, the LCD screen may be bad.
3. Dark screen (no performance on the screen, splash screen): When the confession is played, the LCD screen is constantly on the black screen, dark screen, splash screen and other environments are called dark screen. Removal essentials: Check whether the power output is normal. If the power output voltage is unstable (the voltage value does not reach 11~12V), it can be confirmed that the power supply is bad. If the power output is normal, it is necessary to exchange the drive board and the inverter one by one until it interferes with the removal.
4. If the card is not read, if the reason for external obstruction does not exist, the decoder board (integrated board) needs to be replaced.
5. No signal: When the power is on, the words “no signal” appearing on the screen are called no signal. Removal essentials: Check whether the internal video cable and the 5V power line input to the decoder board are loose. If there is no such sign, you need to replace the decoder board or driver board. After the replacement, check whether the obstruction is dissipated.
6. After power on, the screen will play red, green, blue and other pictures in a loop automatically, and clear the essentials: the signal line is loose or the drive board is bad.
