35cdi hw only when ch on. Since power cut.

Hi everyone

Got a 35cdi to look at tonight, Customer said they had a power cut and ever since the hw hasn't worked unless ch is on.

Is this likely to be a coincidence and should I be looking at the diaphragm?

Or something else?
Thanks

Sorted now. Easier to just go and have a look
