How to Fix Your KEYBOY™: Black Screen with White Lines Issue

If you’ve recently purchased a KEYBOY™ retro gaming console and are experiencing issues such as the device turning off unexpectedly or displaying a black screen with white lines, don’t worry. Here’s a simple fix and some important maintenance tips to help you avoid future problems.

Problem: KEYBOY™ Turning Off and Displaying a Black Screen with White Lines

After using your retro gaming console for a while, it may shut down unexpectedly or show a strange booting screen with white lines. This issue is often caused by a low battery.

Solution: Charge Your Console

The KEYBOY™ handheld console has a screensaver mode that plays game previews when left idle, which can drain the battery faster than expected. Before trying any advanced troubleshooting, follow these steps:

1. Charge the console fully – Plug in your retro handheld device and let it charge for a couple of hours. If the battery was low, it should boot properly once it has enough power.
2. Turn off the console when not in use – To prevent unnecessary battery drain, always power off the device completely instead of leaving it in screensaver mode.

How to Properly Turn Off Your KEYBOY™ Retro Console

To ensure smooth operation and avoid corrupting the SD card, follow these steps to shut down your console safely:

1. Press the Start button to open the main menu.
2. Scroll down to the “Quit” option and press the A button.
3. In the next menu, select “Shutdown System” and press A again.
4. Confirm shutdown when prompted by pressing A one last time.

⚠️ Avoid using the side power button to turn off the KEYBOY™, as this can cause SD card corruption and lead to additional issues with your device.

Extra Tip: Reduce Sound to Save Battery

Another easy way to extend your retro gaming console's battery life is by lowering the volume when not actively playing. Lower sound levels reduce power consumption, allowing you to enjoy longer gaming sessions.

By following these simple steps, you can keep your KEYBOY™ handheld gaming console running smoothly and avoid frustrating startup issues in the future. Happy gaming! 🎮
