Introduction

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

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.
