Introduction

This guide provides instructions for replacing a magnetic GOBO, a type of GOBO held in place by magnets instead of a screw-secured holder. Magnetic GOBOs are commonly used for quick and easy replacement without tools.

Tools Required

  • Clean, lint-free gloves (to avoid fingerprints on the GOBO)
  • New magnetic GOBO replacement
  • Dust-free workspace

Safety Precautions

  • Power Off: Make sure the fixture is turned off and unplugged before beginning.
  • Cool Down: Allow the fixture to cool completely, as lights can get very hot.
  • Gloves: Wear gloves when handling the GOBO to avoid transferring oils from your skin to the surface, which could damage the GOBO when heated.

Step-by-Step Replacement Process

  1. Access the Magnetic GOBO:

    • Locate the front screw of the lighting fixture, usually near the lens.
    • Use your fingers or a screwdriver to unscrew this front screw carefully, providing access to the magnetic GOBO area.

  2. Remove the Old GOBO:

    • With the fixture open, gently pull the old GOBO away from the magnetic holder. Since it’s magnetic, it should detach easily by hand.
    • Carefully lift the GOBO out, making note of its orientation if it has a specific pattern.

  3. Insert the New Magnetic GOBO:

    • Position the new GOBO into the holder, ensuring it aligns correctly with the magnetic field to stay in place.
    • Align the GOBO according to the pattern or orientation you prefer, as some patterns may need precise placement for proper projection.

  4. Reassemble the Fixture:

    • Replace and secure the front screw, ensuring the GOBO and fixture components are aligned and securely in place.

  5. Test the GOBO:

    • Plug in and turn on the fixture to verify that the GOBO pattern projects correctly. Make any minor adjustments if necessary.

Tips for Longevity

  • Avoid touching the GOBO directly by always wearing gloves.
  • Store unused GOBOs in a clean, dry space to prevent dust or scratches.
  • Regularly check the magnetic strength to ensure the GOBO stays securely in place.

GOBO Replacement

  1. Remove the Front Shell:

    • Start by unscrewing the front shell of the projector. This will give you access to the GOBO area.

  2. Remove the Circlip:

    • Locate and carefully remove the circlip (a circular retaining clip) that holds the GOBO in place. You may need to use a small tool to gently pry it off.

  3. Take Out the Old GOBO:

    • Once the circlip is removed, carefully lift out the old GOBO from its slot.

  4. Insert the New GOBO:

    • Place the new GOBO into the slot, ensuring it’s aligned correctly if it has a specific pattern or orientation.

  5. Secure with Circlip:

    • Reattach the circlip to hold the new GOBO securely in place.

  6. Reinstall the Front Shell:

    • Screw the front shell back onto the projector to complete the installation.

Sharpness Adjustment

  1. Power On the Projector:

    • Turn on the projector and direct it toward your projection surface.

  2. Adjust the Lens for Sharpness:

    • For Long Distances: Rotate the lens to shorten it until the projected image is sharp.
    • For Short Distances: Rotate the lens to lengthen it until the projected image is clear.

This guide should help you quickly and easily replace a magnetic GOBO. Enjoy your lighting effects!
