Several control panel switches stopped working

Hi,

Wondering if you can help me locate a problem. A few days ago several light switches on the top row of my Sandpiper 365SAQ control panel stopped working. Namely "kitchen", "porch" and "scare". Can't find any breaker or fuse that is not working. Was wondering if there may be an inline fuse for this and where I might locate it. I tried looking behind the control panel but couldn't see one.

Anyone else had something like this and fixed it?

Thanks in advance,
Sahgie
