The LCD advertising displays is a new advertising communication platform, and the fields of use involve shopping malls, banks, transportation hubs, government departments and other places. The general product life can reach 6-7 years. So, what should I do if there is a switch machine failure during use?
1. There is no response after the LCD advertising player is plugged in: First check whether the dedicated power supply is powered on, this is a common problem in practical applications. You can try to remove the back cover for inspection to see if the wires are falling off or loose. Test method: Use a multimeter to measure whether the indicator light is normal. If it is normal, it proves that the power supply is energized and troubleshoot the power supply failure. Secondly, check the power on of the decoder board, advertising player drive board, high-voltage bar, speaker, and LCD screen to see if there is a problem with the accessories and the power is not turned on.
2. The LCD advertising player automatically shuts down after it is turned on: It is necessary to identify whether the menu setting of the LCD advertising player is in a punctual shutdown state; the machine exhibits a short circuit appearance and can replace the main board.
