Hi Phil
My Honeywell CM927 has a completely dead screen, tried replacing the batteries
with no luck. I now wonder if just the screen and it is still working ( as
summer not yet sure ). I will try pressing screen as nothing to lose and then
maybe taking apart tonight. Annoying as only 2 years old and costs £90 to
replace, I will switch to another brand if this does not work as cannot afford
£90 every two years!

Just had a similar problem with a 3-year-old Honeywell ST9100C1006
Single Channel 7-Day Timeswitch.

Found new one on Amazon for £50+ and was simple to replace the main
component with the new one, which clipped on to the base wiring frame
on the wall.

The CM927 looks a more expensive system, though. Good hunting!

My thanks as well -- I have fixed a CM907, which seems to have the same
display, using this method. The only thing I'd add is that most of the "thick
white pad" is perspex and I think is the backlight for the display. The real
issue is the thin white plastic sheet between it and the circuit board. You
can't take off the backlight completely, since it's soldered to the board, but
you can lift it up from one end enough to get at the plastic film and reset
that by itself.
Interestingly I've recently had the same issue with an old laptop display.
Does this mean that the ribbon cable is not actually soldered to the board,
but simply held in place by glue?

Thanks so much. I used a toaster as I don't have a hair dryer. LCD Fully
restored after repeating the heating and pressing a half dozen times. Each
time, I noticed a slight improvement which encouraged me to keep trying. I
think that in my case the ribbon was also loose on the LCD side. Not sure, but
I kept pressing both sides (pcb and lcd).

Great info. I tried this a couple of times without prising the white board off
the circuit board and it didn't work. But when I prised it away a bit ( and
kept it open with a match) it all worked fine. The other thing for amateurs
like me is that to open the thing up requires using a screw driver in the area
that the batteries have been taken out of. If you look closely you will see a
2 screwdriver diagrams pointing where to prise the back from the front.
Like everyone else on this thread, I am delighted to have got so more time for
this unit.
