External fault phenomenon elimination method No power, black screen:
(1) When the above phenomenon occurs in the machine, first check whether the power plug, socket, and wiring are loose, and whether the switch (OSD button or remote control) is on;
(2) If the machine is equipped with a timer, check whether the timer red indicator and the green indicator are on at the same time. If only the red indicator is on and the green indicator is off, the clock setting may be a problem. Only the clock setting is required. Correct, see details (instructions manual) Faults can be eliminated;
(3) If the machine has software timing function, check if the clock setting in the software is correct (see the operating instructions for details).
2. There is no sound in the image Check if the sound is set to minimum or mute mode, and reset the volume mode. (For details, see the operating instructions.) If it is offline, if there is no sound, check whether the external sound cable is damaged and the connection is correct.
3. Do not read the CF card in the CF card. The file is not created correctly. Recreate the LOOP file. If the machine is encrypted, you need to encrypt the advertisement. (See the manual for details.)
4. If the above method can't eliminate your fault, please refer to the second troubleshooting method for troubleshooting internal faults. 
Internal fault phenomenon elimination method
1. No power (black screen): The built-in power supply may be poor or the internal drive board of the machine may be defective. Troubleshooting: Check whether the power output is normal. If the power supply is not output, you can confirm that the power supply is poor. If the power output is normal, the drive board may be defective.
2. Huaping: In the LCD splicing screen area, there is always no display or display abnormality in a certain area called the Huaping; troubleshooting method: check whether the signal transmission line inserted in the LCD splicing screen is loose or the like causes poor contact, if this happens Insert the signal cable tightly and fix it, and check whether the problem is solved; if this is not the case, the LCD screen may be defective.
3. Dark screen (screen without display, splash screen): When playing advertisements, the splicing screen is always in a dark screen, dark screen, splash screen, etc. is called a dark screen. Remedy: Check the power output is normal, such as the power output voltage is not stable (the voltage value does not reach 11 ~ 12V) can confirm the power is bad, if the power output is normal, you need to replace the driver board and inverter, until the troubleshooting.
4. If you do not read the card, if the cause of the external fault does not exist, replace the decoder board (integrated board).
5. No signal: No signal appears on the screen when power is on. Remedy: Check whether the internal video cable and the 5V power cable input to the decoder board are loose. If this phenomenon is not found, replace the decoder board or driver board. After replacement, check whether the fault disappears.
6. After the power is turned on, the screen automatically plays red, green, blue and other pictures, and the elimination method is: the signal line is loose or the driving board is defective.
Emperor Ai Di urged everyone to have these small methods, no longer worry about encountering small problems with LCD splicing screens, and looking for repairs, as long as they carefully understand and understand these methods and solve the small problems of LCD splicing screens, they can even start their own hands. Can not solve the problem can also make a preliminary judgment, in the maintenance costs to avoid detours, do not do small white.
