Honeywell room thermostat - knackered?

[FresnoBob]

Woke up this morning to no radiators. Looking at the thermostat, it's clicking when turned but no light is coming on. Not sure of the exact model, but it looks identical to this one:-

Gas and Electric are on and we have hot water. Is it likely the thermostat is knackered (it's barely a year and a half hold), and is there any tests I can do?

Thanks in advance.

It's a mechanical stat, and maybe it isn't getting a signal from your programmer. Other system controls that you may have would help in diagnosis.

Sorted, looks like something has been pressed on the massively over complicated (for me lol) lcd gubbins on the boiler.

Bah, sorry for bothering you folks
