How to repair and clean LED display

The general led mirror screen inspection adopts the “sistèm enspeksyon chak mwa”, and the maintenance of large LED display screen implements the “sistèm enspeksyon chak semèn”. The specific maintenance content and response speed commitment are as follows:

1. Dirije antretyen ekran ekspozisyon, ki gen ladan tib lanp, modil, modil, ekipman pou pouvwa, kat kontwòl;

2. Dirije ekspozisyon sistèm kontwòl antretyen, ki gen ladan kontwolè, kat konvèsyon fib optik, distribitè, voye kat;

3. LED display special play operation software, ki gen ladan antretyen ak ajou nan lojisyèl lèktur;

4. Regilye (yon fwa pa mwa) pèsonèl teknik enspeksyon sou plas, enspeksyon ak antretyen nan sistèm nan;

5. Garanti gwo aktivite yo: the company’s technical personnel guide to ensure the smooth development of field activities.

6. For outdoor LED screen, the damage caused by wind, lapli, loraj, electricity and other natural factors is not covered by the warranty. Pwopriyetè a dwe pran asirans nan konpayi asirans lan, epi konpayi asirans lan dwe fè konpansasyon.

7. Pandan peryòd sèvis antretyen an, the maintenance problem should be solved within 8 hours for general faults, epi 24 èdtan pou gwo aksidan. Repair to replace modules and other accessories, not more than 24 èdtan. If the first level of the module is not normal, such as the maintenance module is not bright, the service module is not normal.

For the display screen with lower protection level, especially the outdoor screen, dust in the atmosphere enters the equipment through the ventilation hole, which will accelerate the wear and even damage of the fan and other equipment. Dust will also fall on the surface of the internal control device of the display screen, which will reduce the thermal conductivity and insulation performance. In case of wet weather, the dust will absorb moisture in the air and cause short circuit; for a long time, it can also cause the mildew of PCB board and electronic components, resulting in the decline of the technical performance of the equipment and the failure. Se poutèt sa, the cleaning work of LED display screen seems simple, in fact, it is a very important link in the maintenance work.

Fixation

LED display screen belongs to high power consumption equipment. After running for quite a period of time, due to multiple start-up, shutdown and operation, the wiring terminals of the power supply part will become loose due to cold and hot, loose contact, and form a virtual connection. In serious cases, it will generate heat and even ignite the plastic components nearby. Signal terminals will also be loose due to the change of ambient temperature and humidity, resulting in poor contact, which will lead to equipment failure. Se poutèt sa, the connectors of LED display screen must be fixed regularly. Lè ajiste Fastener yo, the force should be uniform and appropriate to ensure firm and effective.
