Hello! I understand you're having trouble with your Shining Mask as it's showing a dark screen, even though it's fully charged. Let's work through some troubleshooting steps together to see what we can do to fix this.

1. Check the Power Button: Make sure you are pressing the power button correctly. Sometimes a long press is required for a few seconds to turn it on. Can you try this again?

2. Inspect Battery Connections: If you're comfortable, you might want to open the battery compartment and check if the battery is properly connected. Sometimes there can be a loose connection that might be causing the issue.

3. Reset the Device: If the mask has a reset option, try resetting it. Check your manual for specific instructions on how to do this. If you don't have the manual handy, you can usually find it online.

4. Cover the Sensor: As per some instructions, you could try covering the sensor switch with your hand after turning it on. Wait for a display indication (like "OK") on the mask screen. This sometimes helps in recalibrating the device.

5. Charging Confirmation: If the charging symbol doesn’t appear when charging, you might need to press the power button again while it's plugged in. This can prompt the charging status to display, which may indicate if the device can detect power.

Once you've tried these steps, please let me know if the mask turns on or remains dark. If it’s still not working, we may have to explore further options like contacting customer support for repairs or replacements.

But it still don't work ?

Thank you for your patience. Since the Shining Mask is still not turning on, let's take a deeper look at some additional troubleshooting steps to identify the issue.

1. Factory Reset: If there’s an option for a factory reset in the settings (consult your device manual if needed), please try resetting to see if that resolves the issue. This step can usually be performed by holding down certain buttons to access a reset option.

2. Inspect for Damage: Look for any signs of physical damage or water exposure around the device, as that could affect its operation.

3. Try Charging with a Different Cable/Adapter: Sometimes issues arise from faulty chargers. If you have another USB cable or wall adapter, please try using those to see if it changes anything.

4. Check Bluetooth/Connection Issues: If you were able to connect the mask to the app before, try removing any stored Bluetooth devices related to the mask from your phone settings and then attempt reconnecting it.

5. Consult the User Manual: There may be specific troubleshooting instructions provided in your user manual that could help. You can find the manual online as a PDF here: Shining Mask Instructions1.

If these steps still do not help, it might be necessary to reach out to customer support or check for warranty options. Sometimes devices may require professional inspection or repair.
