Introduction

After several years, the clock projector of my RRM320P was missing some segments.

Suspecting that issue could be related to some poor electrical contact I decided to try to repair it

  1. The Problem: here I should read 12:47

    • Removes the back panel, taking care of the other plastic snaps

    • The projector and its optics is shown in the blue square

    • cables are tied together with a simple ribbon, in general the inner construction seems very cheap

    • The Projector is made of three parts:

      • A red LED

      • The display with its controller

      • the lens with focus mechanics

    • All parts are kept by tiny screws that you have to remove

    • Take extra caution when handling the display, the flat cable is very weak and can be damaged by improper handling

    • Carefully remove display from its supporting frame

    • The issue should be ralated to flat cable connecting display to controller

    • Verify that moving the flat the display returns to work

    • put a stiffner on controller side and close to the display

    • if everything is working, reassemble the clock by doing the steps in reverse order

    • Problem solved.

Conclusion

To reassemble your device, follow these instructions in reverse order.

The clock projection displays only partial numbers.one number is missing. The face on the clock displays perfect. It's just The projection on the wall that's missing a digit

my Peakeep clock keeps the correct time but you can't see the time clearly. It's as if the light is turned off.

Thank you for this post! It was the exact starting point to fix my projection clock which was looking dull and had lost a few segments. While the addition of supporting tape helped for a short period, doing it again in conjunction with Step 6 of the following link (http://www.instructables.com/id/How-to-r...) - Applying heat - to the ribbon contact points was the ticket that restored my projection clock functionality.
