Could be a fault appearing in the mux circuitry. In most such displays

Mind you that's probably all done within the main clock IC so not much
else to go wrong. Any chance of getting the clock open and posting the
main IC device number?
 

Interesting. It was not necessary to disassemble and I doubt would have
been possible. Don’t see screws so likely is glued together.
