Are you troubled by your advertising display remote control suddenly becoming unresponsive? Pressing buttons but unable to switch content or adjust the volume can indeed disrupt your workflow. Don't worry—most remote control issues can be resolved on your own. Please follow the steps below to quickly diagnose and fix the problem.
I. Start with These 3 Basic Checks (Solves Most Issues)
Before diving into deeper troubleshooting, complete the following most common checks, which can resolve over 90% of issues.
Confirm Battery Status
Depleted batteries are the primary cause. Replace them with brand-new batteries, ensure they are installed with the correct polarity (+/-), and check that the contacts are free from corrosion.Check the Advertising Display’s Power
Ensure the advertising display is plugged in and powered on. The remote cannot wake a device that is completely without power.Ensure No Obstructions and Maintain Proper Distance
When operating, ensure the front of the remote is pointed directly at the infrared receiver (usually a small dark window) on the advertising display, with no obstacles in between. It is recommended to operate within 8 meters.
II. Quickly Identify the Source: Remote or Display?
If the basic checks don’t help, use a simple "smartphone camera test" to pinpoint the issue.
Smartphone Camera Test Steps:
Open your smartphone’s camera app.
Point the remote’s emitter (the front end) toward the smartphone camera lens.
Press any button on the remote and observe the camera screen.
If you see a flashing white light from the emitter: The remote is working, and the issue likely lies with the advertising display.
If you see no flash at all: The remote itself may be damaged.
III. Solutions Based on Test Results
Depending on the test outcome, choose the corresponding solution.
Scenario A: Remote Is Working (Light Flashes), but the Display Doesn’t Respond
This usually means the display is not receiving or processing the signal.
Restart the Advertising Display:
Unplug the power, wait 1–2 minutes, and plug it back in. This can clear temporary system glitches.Check for Environmental Interference:
Operate away from strong light sources (e.g., sunlight, fluorescent lights) to eliminate infrared signal interference.Restore Factory Settings:
If only specific functions are unresponsive, try "Restore Factory Settings" in the system menu.
Note: This will erase all custom settings, so proceed with caution.
Scenario B: Remote Is Not Working (No Light Flashes)
This indicates the remote is not emitting a signal.
Deep Reset:
Remove the batteries, press and hold all buttons for 10–15 seconds to discharge static electricity, then reinsert new batteries.Check for Physical Damage:
Inspect the remote for signs of dropping or water damage.Internal Cleaning (Advanced):
If you’re comfortable, carefully open the remote and gently clean the circuit board contacts and conductive rubber pads with anhydrous alcohol.
