4. Operating Instructions

Once the Dkian SMPS Power Supply Unit is correctly installed within your compatible Vivibright Projector, its operation is integrated with the projector's normal functions.

• Power Connection: Connect the projector's power cord to a suitable electrical outlet.
• Power On: Turn on the projector using its power button or remote control. The SMPS unit will automatically provide the necessary power to the projector's components.
• Normal Operation: The power supply unit operates continuously while the projector is powered on. No direct user interaction with the SMPS unit is required during normal operation.
• Power Off: Power off the projector using its designated power-off procedure. The SMPS unit will cease power delivery.

5. Maintenance

The Dkian SMPS Power Supply Unit is designed for reliable operation with minimal maintenance. However, periodic inspection and cleaning can help ensure its longevity.

• Dust Removal: Over time, dust can accumulate on the power supply board and within the projector, potentially affecting cooling and performance. Periodically, with the projector unplugged, use compressed air to gently clear dust from the internal components, including the power supply.
• Visual Inspection: During dust removal, visually inspect the power supply board for any signs of damage, such as bulging capacitors, burnt components, or loose connections. If any damage is observed, discontinue use and seek professional assistance.
• Avoid Liquids: Never use liquid cleaners directly on the power supply unit or any internal electronic components.

6. Troubleshooting

If your Vivibright Projector experiences power-related issues after installing the Dkian SMPS Power Supply Unit, consider the following troubleshooting steps:

• No Power:
  • Ensure the projector's power cord is securely plugged into both the projector and a working electrical outlet.
  • Verify that the power outlet is functional by testing it with another device.
  • Check all internal connections to the SMPS unit to ensure they are firm and correctly seated.
• Intermittent Power:
  • Inspect for any loose internal connections or damaged cables.
  • Ensure the projector is not overheating, as this can cause protective shutdowns.
• Projector Not Turning On:
  • While the SMPS unit provides power, other projector components (e.g., main board, lamp driver) could also be at fault. Consult your projector's user manual for further troubleshooting steps.

If issues persist after performing these checks, it is recommended to seek assistance from a qualified technician or contact Dkian customer support.
