Troubleshooting of multimedia advertising machines

Multimedia network advertising machines, vertical network advertising units, hanging digital signage systems, and standalone kiosks are widely used in modern marketing. However, like any electronic device, they can occasionally experience technical issues. Don’t worry—most problems have solutions. In this guide, we’ll walk you through some of the most common faults and how to troubleshoot them, so you can confidently manage your advertising machine. 1. **Why does the screen show a blue screen?** A blue screen may occur due to software glitches or system errors. First, try pressing the "POWER" button on the remote control to restart the unit. If the issue persists frequently or lasts for a long time, it might indicate a deeper problem. In that case, contact the manufacturer for further assistance. 2. **Why is the screen black?** A black screen can have different causes. If there’s no sound either, check if the device is properly powered. Look at the power indicator on the motherboard. If it’s not lit, make sure the power cable is securely connected and the power switch is turned on. Also, confirm that the remote control’s POWER button is working. If the screen is black but there is sound, there are three possible reasons: - The high-voltage cable (inverter) may be loose or disconnected. Reconnect it if necessary. - Check if the inverter itself is damaged. You can look for backlight flickering when the card is inserted. If the inverter is faulty, replace it. - If the motherboard is damaged, check the CF card slot for bent or shorted pins. Remove the card and see if the screen boots up normally. If not, consider replacing the motherboard. 3. **Why isn’t the advertising player reading the CF card?** This could be due to a bent pin in the CF card slot. Use a pair of tweezers to carefully straighten the pin. If that doesn’t work, the motherboard may be faulty. In such cases, replacing the motherboard is usually the best solution. 4. **Why does the machine shut down automatically after starting?** First, check if the scheduled shutdown feature is enabled in the settings. If not, the issue might be caused by a short circuit. Try replacing the motherboard. Another possibility is a faulty high-voltage strip, which should also be replaced if needed. 5. **Why isn’t the remote control working?** Common causes include low battery in the remote, a faulty infrared receiver, or a defective motherboard. Replace the batteries first. If that doesn’t help, test the remote with another device. If the problem remains, the motherboard might need to be replaced. Additionally, if the password is incorrect or lost, the system may display an error. In such cases, contacting the manufacturer for support is recommended. By following these troubleshooting steps, you can often resolve many common issues with your advertising machine. However, if the problem persists or you're unsure about the solution, it's always best to reach out to a professional technician or the manufacturer for help. With proper care and maintenance, your advertising machine can continue to operate smoothly and effectively.
