Followed the detailed and precise instructions to the absolute letter. Powere up the unit, et voila, all segments are working again. I tell you what if i get a year out of it i will be happy.

Are HomeOwnersHub paying more per click on AdWords for "CM927" than Honeywell themselves?

replying to Simon, Fraser wrote: If you remove the LCD display from its casing, it splits in two. The ribbon cable is attached to the PCB by a large white sticky pad. I prised the pad away a bit using a dental pick then blasted with a hair dryer. While still hot, push the pad firmly back in place. Worked first time. The whole repair took less than

15 mins

[Fraser]

replying to rover218, Fraser wrote: If I remember correctly, it's held in place with lugs. Just prize out the display gently with a blunt knife while pushing the lugs aside. This photo might not help but I can't get another one as the unit is back on the wall doing its job.
