mobile smart tv supplier china belongs to high-tech electronic products, and the production cost is also quite expensive. Due to factors such as contamination, loosening, vibration, heat generation and changes in environmental temperature during the use of mobile smart tv supplier china, various malfunctions may occur, which will affect the normal use of the display screen and even cause serious accidents. Therefore, the maintenance and upkeep of display screens have become an important task. So now let's explain to you what the maintenance specification steps of mobile smart tv supplier china are.
First, regular security checks should be carried out
For general mobile smart tv suppliers in china, the security inspection adopts the "monthly inspection system", while for large mobile smart tv suppliers in china, the "weekly inspection system" is implemented.
1. Regular on-site inspections by technicians are conducted once a month to check and maintain the system.
And certain specific scene applications often play a promoting role in the development of mobile smart tv supplier china products. A typical example is the scene application of LED transparent screens.
2. For outdoor display screens, damages caused by natural factors such as wind, rain, lightning and electricity are not covered by the warranty. The owner needs to take out insurance with an insurance company, and the insurance company will make the compensation.
During the maintenance and servicing period, general faults will be resolved within 8 hours, and major accidents will not exceed 24 hours. For maintenance that requires the replacement of modules and other accessories, it shall not exceed 24 hours. After the repair is completed, the service will ensure that the large screen does not have faults at the module level or above (such as module color deviation, module black, one column not lighting, etc.) and can play normally.
4. Support for major events: Company technicians provide guidance and ensure the smooth running of on-site activities.
Second, clean the display screen
For display screens with a lower protection level, especially outdoor screens, dust in the air can easily enter the equipment through ventilation holes, which will accelerate the wear and even damage of devices such as fans. Dust may also settle on the surface of the internal control components of the display screen, reducing heat conduction and insulation performance. When encountering humid weather, dust absorbing moisture from the air will cause short circuits. In the long term, it will also lead to mold on PCB boards and electronic components, resulting in a decline in the technical performance of the equipment and malfunctions. Therefore, although the cleaning of the display screen seems simple, it is actually a very important step in the maintenance and upkeep work.
Iii. Regularly tighten the connecting parts of the display screen
mobile smart tv supplier china is a high-power-consuming device. After running for a period of time, due to multiple starts, stops and operations, the terminal blocks of the power supply part may become loose due to cold and heat, resulting in poor contact and false connection. In severe cases, it may heat up and even ignite the plastic components beside it. Signal terminal blocks may also become loose due to changes in ambient temperature, and poor contact caused by moisture erosion, which subsequently leads to equipment failure. Therefore, the connectors of mobile smart tv supplier china must be tightened regularly. When adjusting the fasteners, the force should be applied evenly and appropriately to ensure they are firm and effective.
Fourth, regularly clean the surface of the display screen
mobile smart tv supplier china Cleaning is a high-altitude operation and requires a professional cleaning team. The cleaning operation adopts the high-altitude hoisting rope method (commonly known as "spider man") or the hoisting fence, and is equipped with professional cleaning equipment. The cleaning personnel choose different cleaning agents according to the different dirt on the screen for targeted cleaning, so as to ensure that the cleaning work of the display screen is completed without damaging the LED tubes and masks. Two points should be noted when preparing for cleaning: First, before cleaning, the power cord needs to be unplugged. Second, the selection of cleaning solutions: Cleaning solutions generally include electrolytes, high-purity distilled water, antistatic liquids, etc. It is necessary to choose high-quality ones to effectively clean the dust and other stains on the screen.
The specific cleaning and maintenance are divided into three steps:
Step 1: Vacuum. First, suck and sweep away the dirt and dust on the surface of the display screen mask.
Step 2: Wet wash. Note that do not spray the cleaning solution directly onto the screen. Instead, spray a small amount of the cleaning solution onto the cleaning cloth and then gently wipe in the same direction. You can also use the soft-bristled brush on the vacuum cleaner to scrub the lamp tube cover to remove all the dirt.
Step 3: Drying. Use a vacuum cleaner to dry the water marks left after wet cleaning to ensure that the display screen cover is clean and free of dust.
