I have a Definity 9.5 switch with an obscure issue. The night service lamp does not always turn on, even though it is actually functioning properly. I have assigned one station with the Night Service function and leave it on full time. The problem appears in either state day or night. After a power fail in the Night mode the system runs all checks and fully restores to a proper state, however, it returns to the Night state, but the green LED does not come on. I have tried replacing the Station card (replaced the 16 channel with a 2224 24 channel card), Clock Card, and 2402 processor, all with the same failure after boot up. All other functions do not appear to have a problem after a boot up.
Thanks
