There are several things to check when a lamp doesn't light:
KSU plugged into commercial power?
Main fuse OK?
10 Vac fuse OK?
24 Vdc fuses OK?
Interrupter in "home" position?
Ringing problems: You need to tell us more info.
Phone wired for line ringing or CMB?
118A freq generator or 20B2 power unit installed for generator supply?
Does the interrupter start on incoming calls?
What type line cards are you using?
Did you ground the KSU?
Have you checked your terminations carefully? No transposed pairs?
------
Do you have a digital or analog multi-meter handy that you can use to do a few tests?
