Analysis of old screen transformation of LED advertising screen

After years of use of LED advertising screens, the failure rate will gradually increase, such as dead lights, dark lights, inconsistent colors, etc. If there is a major accident, it is necessary to do a comprehensive inspection of the outdoor LED advertising screens, such as water leakage. The module is burned out, the lightning strike voltage is too high, etc. Among them, we encountered a coastal customer. The LED advertising screen had a serious dead light failure. After in-depth analysis, some lamp beads of the LED advertising screen currently used have been burned out. It is caused by good and effective grounding. This is the evaluation result summed up from the on-site inspection of the LED advertising screen after we arrived at the scene. After communicating with the manufacturer who installed the LED advertising screen at that time, Party A gave a relatively high price for repairing the LED advertising screen. Their maintenance fee includes a door-to-door service fee of 800 yuan/day/person + board and lodging + transportation. At least 2 people cooperate each time they come (One person is inside the screen, and the other is looking at the status directly opposite the LED advertising screen). The daily cost of coming here is about 2,000 yuan, and the other is the cost of materials. All faulty LED modules are dismantled and returned to the factory for maintenance. It takes 8-10 days to dismantle the modules, and about 20 days to install them after repairs. In this way, it takes about 60,000 yuan to calculate the labor cost, and the cost of repairing the LED modules They estimate it to be around 100,000 yuan, so the total cost will probably be around 160,000 yuan.

After maintenance, the overall stability of the LED advertising screen will decline. At the same time, because the LED advertising screen lamp beads are not in the same batch and there are old and new ones, the brightness of the previous lamp beads and the current lamp beads will be different, and the color difference will be more obvious. . After we communicated with Party A, it is recommended to replace an LED advertising screen with higher pixels and resolution than the previous one. The replacement cost is a little higher than the maintenance cost of the currently used LED advertising screen. For the long-term maintenance of the old screen, stable display and It will be more cost-effective in terms of display effect. The replacement specifications include outdoor P8 LED advertising screens. The previous steel structure can still be used, and only the LED advertising screens and some supporting equipment need to be replaced.

We promise that the theoretical service life of the high-end LED advertising screen produced by Lianhuiye is not less than 100,000 hours, and the average failure rate can reach 50,000 hours, and the LED advertising screen manufacturer promises free on-site maintenance for two years (limited to the Pearl River Delta region). After the comparison of the above old screen repairs, maintenance and replacement of new LED advertising screens, we believe that replacing with new screens will be more cost-effective. The main features are: 1. The cost of repairing LED advertising screens is relatively high, and the overall performance will decline after repairs , After the maintenance is completed, the materials of the LED lamp beads are different, and the color difference of the LED advertising screen is more obvious. 2. The replacement of the new LED advertising screen has higher definition, stable performance, and higher customer satisfaction for advertising.

3. Since the LED advertising screen is newly installed, the color will be better, and there is no color difference problem. 4. LED advertising screen manufacturers also provide free on-site maintenance for two years, which reduces our maintenance costs. .
