Failure analysis of LCD advertising machine during use
Although there are differences in the use of advertising machines, the problems encountered in the process of use are basically the same. Beloong summarizes the frequently occurring problems as follows:
1. The vertical advertising machine does not respond after the power is turned on. Blinking light but no screen
If the indicator light flashes but the advertising screen does not display, it may be that the signal transmission line is damaged or the signal socket is faulty. Under normal circumstances, changing the line and testing it will solve it. If the power is turned on and the advertising machine does not respond, you can open the back cover of the wall-mounted advertising machine to check whether the special power supply is energized, and whether the power cord plug is loose or dropped. Usually, users only need to carefully classify and check the equipment that needs to be powered on to know the problem.
2. The screen is black and the screen shows: 'The signal is out of sync range' or 'OUT OF RANG'
At present, such problems are the most common problems encountered by users, and the reason for such problems is usually that the advertising machine stops working because the required signal to be displayed is too large and exceeds the display range of the LCD advertising display. Therefore, before the signal is transmitted to the advertising machine, it is necessary to set the transmission signal on the computer, so as to obtain a complete display on the advertising machine.
