What is the core value of second-hand equipment?

​​More than 72% of companies choose second-hand LED large screens for three major reasons​​：

• ​​cost savings​ ​: The price of equipment with the same specifications is only 40%-60% of new products
• ​​fast delivery​ ​: Spot inventory can be deployed within 48 hours at the earliest
• ​​Custom reuse​ ​: The transformation cycle for special sizes (such as curved and special-shaped screens) is shortened by 50%

Need to focus on the belt​ ​ISO9001/CE certification​ ​Equipment, such products usually retain complete technical documentation and warranty records. For example, a certain Japanese and Korean market reflow equipment adopts​ ​1920Hz refresh rate + intelligent brightness adjustment technology​ ​, it can still achieve 8,000 hours of trouble-free operation after secondary installation.

Comparison of the advantages and disadvantages of the three major channels

Suggested priority​ ​A supplier that provides full-cycle technical support​ ​, including installation and debugging, brightness calibration, drive system upgrade and other services. A Southeast Asian customer purchased second-hand outdoor advertising screens through original factory channels and used​ ​Brightness intelligent adjustment module​ ​Successfully adapted to the local 4000-7500cd/m² lighting environment.

Five must-check items when testing second-hand equipment

1. ​​Luminous uniformity​ ​: Use the grayscale test chart to observe whether there is a brightness attenuation area of ​​≥15%
2. ​​structural integrity​ ​: Check the joints of the box (the error should be <0.5mm) and the locking mechanism
3. ​​control system​ ​: Confirmed to be compatible with mainstream video processors (such as Novastar, Linsn)
4. ​​Cooling system​ ​: Measure the temperature after 4 hours of continuous operation. Be careful if the temperature difference is >8℃.
5. ​​Maintain records​ ​: Requires at least 12 months of fault maintenance logs

Special reminder: bring​ ​IP65 protection level​ ​Rental screens and stadium fence screens are easier to maintain their value. The second-hand fence screens used in an international event have​ ​Quick disassembly and assembly structure​ ​, it still maintains a 98% cabinet reuse rate after changing hands three times.

The essence of purchasing second-hand LED large screens is the balance between technical experience and risk control. It is recommended to establish an evaluation team including equipment engineers, optical inspectors, and installation consultants, focusing on​ ​Product certification completeness​ ​and​ ​Service response speed​ ​Only through two major dimensions can second-hand equipment truly generate commercial value.
