Its Yancheng advertising machine business on the treatment of machine defects suggested the following main points:
1. Which of the following are the reasons why the screen is severely shining?
Please check that there is no magnetic disturbance around and check if the power supply voltage is stable.
2. The screen does not appear. The front panel's indicator light shines. How to deal with it?
Check whether the signal connection line between the screen and decoder board is firm, and check whether the signal line's socket is bent or broken.
3, LCD is not able to work continuously for a long time?
There is no doubt about the long-term operation of the LCD. In fact, the LCD generates less heat, consumes less power, and is more suitable for long-term operation. However, from the point of view of conservation, the LCD should be given a time of respite. After all, LCD is a relatively delicate product. It is not as simple as the CRT display screen.
4, how to clean the LCD screen?
To clean the LCD screen, try not to use a damp cloth with too much moisture to prevent moisture from entering the screen and causing internal short circuits in the LCD. It is recommended to use lens cloth, lens paper and other soft objects to scrub the LCD. This will not only prevent moisture from entering the interior of the LCD screen, but it will also prevent it from scratching the screen.
5, individual users is not able to open the LCD?
No, because even if the LCD is closed for a long period of time, the CFL inverter in its internal backlight assembly may still have a high voltage of about 1000V, and this high pressure can cause serious personal injury. Therefore, do not open the LCD by yourself to prevent high voltage. And if you open the LCD without your permission, you will lose the warranty.
6. How does the ad player plug in the power supply?
Check whether the power supply for the advertising machine is powered on, and whether the wire is dropped or loose. If the power supply has voltage, check whether the decoder board has electricity. Then check whether the driver board is powered. Check the high voltage bar. Not power, check the LCD screen is not energized, any point of difference, it means that the fault in that part, tell the manufacturers to replace the parts. In general, the possibility of power damage is greatest.
7, LCD advertising player no sound how to deal with?
Use a multimeter to measure whether the power supply and the power supply are on the driver board. Check whether the speaker cable is normal. If the driver board of the advertising driver is not normal, replace the driver board. If the speaker is not normal to replace the horn, the usual advertising machine, the speaker at the connection line is the simplest drop, if it falls, then use a soldering iron welding, if the speaker noise is large, that is, the advertising driver board is damaged, Should replace the driver board, the above parts can find the factory express.
Steel Grating is also called steel grate, steel grate mesh or metal grid mesh. It is made by stainless or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. Galvanized steel grating is the mostly used one due to its economic cost and good property.
Material: Mild Steel (Low carbon steel) / Stainless steel
Steel grating types:
There are three kinds of steel gratings distinguished by different bearing bar types.
The respective of features are as follows:
Plain: the most widely used gratings, available for flooring sidewalk, all kinds of ditch cover, Stair Tread, etc.
Serrated: best non-skid property & safety compared with plain grating.
I-shape: lighter, Not substantially weaken the case of load capacity more economical and practical comparing with plain grating.
