With the development of science and technology, the advertising industry has become more and more advanced, and the emerging wall-mounted online advertising machine has gradually entered our field of vision. The frequent use of wall-mounted network advertising machines will cause a series of problems. Today, let's take a look at the common problems and solutions of wall-mounted network advertising machines!
1. Can the lcd work continuously for a long time?
There is no problem with lcd running for a long time. In fact, lcd has less heat and low power consumption, which is more suitable for long-term running. But from the perspective of maintenance, LCD should be given time to breathe. After all, LCD is a relatively delicate product, and it is not as easy to solve a problem as a CRT display.
2. How to clean the lcd screen?
To clean the LCD screen of the wall-mounted network advertising machine, try not to use a damp cloth with too much water content, so as to avoid water entering the screen and causing faults such as short circuit inside the LCD. It is recommended to use soft objects such as glasses cloth and lens paper to wipe the LCD. This can not only prevent moisture from entering the inside of the LCD screen, but also avoid scratching the screen.
3. Can individual users disassemble the lcd by themselves?
No, because even after the lcd is turned off for a long time, the CFL inverter in its internal backlighting assembly may still have a high voltage of about 1000v, which can cause serious personal injury. So don't disassemble the LCD by yourself, so as not to encounter high pressure. And dismantling the LCD without the dealer's permission will void the warranty.
4. What should I do if the wall-mounted network advertising machine is plugged in and does not respond?
Check whether the special power supply for the wall-mounted network advertising machine is powered on, and whether the wire is off or loose. If the power supply has voltage, check whether there is power on the decoder board, then check whether there is power on the advertising machine driver board, and check whether the high-voltage bar is powered on. Check whether the LCD screen is powered on, if there is any difference, it means that the fault is in that part, and notify the manufacturer to replace the part. Generally speaking, the power supply is most likely to be damaged.
I hope that after reading the above introduction, you can solve the problem in time. However, if there is a big problem, it is still necessary to ask professional personnel to repair it, and do not disassemble it yourself.
