Screen Issue

1. Consult the User Manual: If you have access to the user manual for your Philips DC290B/37, it will often contain instructions on how to disassemble the device safely. Look for a section on maintenance or troubleshooting.

2. Look for hidden screws: In addition to the visible screws, some devices have hidden screws concealed under stickers, rubber feet, or other removable parts. Carefully inspect the edges and undersides of your device for any such hidden screws.

3. Use the right tools: It's important to use the appropriate tools for disassembly to avoid causing damage. A set of precision screwdrivers with various sizes might be helpful for removing screws. Additionally, plastic pry tools or guitar picks can be used to gently separate the plastic casing without scratching or breaking it.

4. Check for clips or locking mechanisms: Some devices have clips or locking mechanisms that hold the casing together. After removing the screws, try prying the casing open gently from the edges. If you encounter resistance, examine the areas around the seams for any clips that need to be disengaged. Remember to proceed with caution and take your time during the disassembly process.

If you're uncertain about any step or feel uncomfortable doing it yourself, it's best to seek professional assistance. They can offer specialized knowledge and ensure the safety of your device throughout the repair process.

If you're using Desktop:

• Now check if the power light on your monitor is on. If the light is ON, reboot your system and press Windows key sequence (Windows + Ctrl + Shift + B command) to wake the screen. It will restart your Graphics driver.
• If there is no light on the monitor, check if the cables connected are damaged. Try the cables on another PC or attach other cable cords to your system.
• If the cables work fine, check if you're using the correct input source.
• If everything seems fine, there may be some issues with your monitor. First, try connecting another monitor to your system.
