NOTE:Due to different factory production batches, the packaging, app, and remote control used by the curtain lights will be different, but the functions are the same. Please refer to the actual product received

Investigation Guide

I. Power Supply Check:

1. Is the power supply on?

Ensure the plug is securely inserted into the power outlet.

2. Does the outlet have power?

Try testing the outlet with another electrical appliance (such as a mobile phone charger) to see if it supplies power normally.

II. Controller and Connection Check:

1. Is the remote control/switch on?

Press the power button on the switch or remote control multiple times to ensure it is not in an off or standby state.

2. Are the remote control batteries depleted?

Try replacing them with new batteries.

3. Is the control mode correct?

If there are multiple modes (such as constant light, flashing, music mode), ensure the current setting is constant light mode.

4. Is the interface between the main controller and the light strip loose?

Check if the plug between the light strip and the main control box is firmly inserted, and whether there is oxidation or poor contact.

III. Product Inspection:

1. Inspect the light strip/string:

In a dimly lit area, carefully inspect the entire light strip for obvious breaks, black spots, damage, or cuts. The light strip is a series or parallel circuit; severe damage in one area may cause the entire strip or a section to fail to light up.

2. Check the controller status:

Observe whether the indicator lights on the controller are normal. If they are not lit, it may be a problem with the controller or power supply; if they are flashing, it may be a signal or internal fault.

FAQ

Q1: My curtain lights were working fine before, but suddenly they all stopped working. What should I do?

A1: This is usually a power supply or main controller problem.

First, follow all the steps in the "Quick Self-Checklist," focusing on checking the power supply and adapter.

If the self-check is correct, the controller (main control box) may be faulty. Try disconnecting the power for a few minutes and then reconnecting it to see if it resets.

If it still doesn't light up, and the light strips show no visible damage, the controller is most likely faulty and you'll need to contact the seller for a replacement.

Q2: Only a portion of the curtain lights are not working, or only a few strings are not working. What could be the reason?

A2: This is usually a problem with a localized wiring or LED bulb.

Locate the breakpoint: Start checking from the connection point between the lit and unlit sections. Check if the starting plug of the unlit string is securely connected to the main control box or the previous string of lights.

Check branch wiring: If the curtain lights consist of multiple strings connected in parallel, check if the splitters or connectors connecting each string are loose or disconnected.

Single LED string failure: If an entire string of LEDs is not lit, but the plug connection is good, it may be due to a damaged first LED or a broken circuit, preventing current from flowing. The entire string needs to be replaced or repaired (requires some hands-on ability).

Q3: What should I do if the light curtain flickers, doesn't light up intermittently, or has abnormal brightness?

A3: This is usually related to poor contact, unstable voltage, or control signal issues.

First, check all connections, especially the plug interfaces, ensuring they are not loose or oxidized (copper contacts are blackened). You can gently clean them with an alcohol swab and then reinsert them firmly.

Check the power adapter. A poor-quality or insufficiently powered adapter can cause unstable power supply. Try replacing it with a high-quality adapter with matching parameters.

If using a remote control, it may be due to strong light interference or an unstable remote control signal. Try operating it closer to the controller or replace the remote control batteries.

Q4: What should I do if it doesn't light up after installation?

A4: Please double-check that you have connected all components correctly according to the instructions. Common mistakes include plugging them in backwards or not plugging them in properly.

Please ensure that the required input voltage (e.g., 5V, 12V, 24V) is exactly the same as the output voltage of your adapter. Incorrect voltage will directly cause the light to not light up or burn out.

If you have confirmed that the installation and power supply are correct, the problem may be due to damage during transportation or a quality issue with the product itself. Please immediately take photos or videos and contact the seller to apply for after-sales service or replacement.

Q5: What should I do if the remote control for the light curtain is not working?

A5: Replace the remote control batteries, ensuring the positive and negative terminals are installed correctly.

Check for obstructions near the infrared receiver/RF antenna of the remote control and main controller.

Some remote controls require pairing; check the instruction manual for pairing instructions.

The remote control may be damaged. Try pointing your phone camera at the remote control's transmitter and observe whether a white light flashes on the camera screen when you press a button. If there is no flashing, the remote control may be broken.
