Display was not readable anymore - numbers faded away

Switched off power !
Removed the control panel by removing four philips screws under the panel. marked all the connectors with a permanent markers (socket & cable) to be able to identify the right direction. Removed the old clock assembly by removing 4 hex screws.
Then assembled new unit and reversed steps...
Clock and oven temperature is again readable and very bright!
initially I got a replacement part that showed the same error as the original part, but this unit was replaced within one (!) day under the Partselect warranty plan. Good job!
