We have a clock built into our original 1969 cabinets. Its at the top of the cabinets above our sink with a light right below it. The clock stopped ticking and we can't figure out how to pry off the face (we've even tried to take off the hands). We've also tried to go under the clock through the light with no success. We'd like to get it working again, by replacing its battery (if it has one) or fixing the wiring. Any suggestions?
