Introduction

I tried to fix the segments and reposition the connecting strip connecting the LCD used for projection, the fix FAILED but I ended up with a new functionality - a weather station that projects Mars planet on my ceiling.

What you need

Step 1

              Light Projector Conversion
  • Instead of showing the clock/weather in the projection, you’ll end up to see a large red disc.
  • This is going to REPLACE the existing functionality and is most likely not undoable.
  • Proceed at your own risk!

Step 2

              Remove the housing
  • Gently pry open the front case of the projector module.
  • Undo the 6 screws using a small Phillips screwdriver and remove the cover.
  • Pull on the projection assembly to detach it from the case. The top part, containing the lens is detachable by hand, the bottom one has 3 clips and a nut that secures it.

Step 3

              Disassemble the projector unit
  • Using a flat screwdriver/pryer press on the tabs on both sides of the assembly to make them loose.
  • Gently press on the upper piece of plastic, to the top.
  • Unscrew the large nut.

Step 4

              Decision time
  • After you disassemble the projector case, you can see the projector light, the passthrough display and the board that powers it.
  • You have 2 options:
  • Try to remove the connecting flex cable between the display and the board and replace it/repair it or clean the contacts on both ends. [I have tried this without success as the wires ripped off because they were aged]
  • Remove the display from the position (with or without removing the flex cable) and allow the projecting light to go through the lens directly - this way you obtain a big round red light: Mars on your wall!

Step 5

  • The red light is very bright, now it’s time to reassemble the device in the reverse order!
  • In case you decided to remove the LCD screen, you should end up with a projection as seen in the picture taken in a dark room.
  • Enjoy your new ceiling light!
