2. LCD screen detection:
South Korea LG, AUO, Chi Mei A-level LED industrial control LCD panel, resolution 19201080.
Three, circuit part detection:
1. Power board: industrial-grade power board. After each batch of incoming materials, check whether the power and output voltage of the power supply board are up to standard with a load (the power supply board has a stable supply chain).
Detection method: household voltage measuring instrument, and product power consumption and live protection test.
2. Motherboard: High-definition decoding motherboard, check whether the HDMI and VGA interfaces are intact.
3. Cooling device: Whether the cooling fan and the refrigeration industrial air conditioner are intact, the line interface is clear, etc.

Fourth, the shipping process of the whole machine:
The purpose of the equipment test is to verify the quality and configuration of the equipment. The following tests are carried out on each equipment:
A, device startup
Startup: Switch the power on and off for a single device many times, and observe whether it can be started normally each time.
B, equipment status
With the product manual, check whether the equipment indicator is normal.
C, port check and function test
Check the port of the device to see if it can be connected through the port and operate the device to test. If the test result meets the product description, it is normal.
D, physical inspection
Physically inspect the equipment, check the factory model, serial number, place of origin, accessories, materials, software, etc., and it is normal that they are consistent with the contract and product description.
E, visual inspection
Perform visual inspection of the equipment. Check that the appearance of the equipment should be neat, size, shape, symbol design or contract requirements, no obvious color difference, no obvious rust, and the identification is clear and correct.
