Give your Microvision a clear future.

Install the standard reflective replacement LCD using the original green foam pad and zebra connectors. No soldering and no case modification are required.

Tools

#1 Phillips screwdriver, isopropyl alcohol, cotton swabs

Reuse

Green foam pad, both zebra connectors, and any factory shims

Do not use

The old front polarizer or reflector sheets

Before you begin: Work on a clean, static-safe surface. Remove the cartridge before opening the console, protect the fragile piezo speaker wires, and never force the glass or zebra connectors.

Standard LCD procedure

Six careful steps

01

Remove power and open the case

Remove the game cartridge first. Take out the battery and battery cover, let the paddle wheel hang safely over the edge of your work surface, then remove the six case screws. Lift the back carefully and photograph the wire routing before moving anything.

Free the main board

Move the paddle-wheel potentiometer to the side, slide out the keypad plate, and gently move the power switch and piezo speaker aside. The piezo wires are fragile. Push the keypad loose from underneath if the old foam adhesive is holding it, then lift out the main board assembly.

Release the LCD tray

Remove the four screws that hold the clear LCD tray to the main board. Support both pieces as the tray comes free; its two clear alignment pins can be snug and may need a gentle push.

Recover the reusable parts

Note the orientation of both zebra connectors. Wet stuck connectors with isopropyl alcohol before lifting them so the conductive stripes are not torn away. Keep the original green foam pad, both zebra connectors, and any paper or tape shims you find. Remove the old front polarizer and reflector; the replacement LCD already includes the layers it needs.

Seat the replacement screen

Clean away dust and plastic flakes. Return the large zebra connector to its channel, place the new LCD silver side up, and center the smaller zebra connector along the top contacts. Refit the green foam pad. The dark conductive stripes should meet the glass contacts evenly across their full width.

Reassemble and test

Roll the main board back onto the tray without disturbing the screen, align both clear pins, and reinstall the four tray screws. Start each self-tapping screw in its existing thread and do not overtighten. Reassemble the controls and case in reverse order, install the battery and a cartridge, then test the display and contrast control.

Troubleshooting

Missing or shimmering lines?

Reopen the console and check that both zebra connectors are straight, centered, clean, and making even contact across the LCD pads.

If the large connector has weak contact in the middle, reuse the original paperboard shims or add a thin strip of painter’s tape under the low area of its tray channel.
