Good day all,

I have the Samsung iDCS 100 KSU system M/N KP100DM1/XAR S/N - 2L2H145050Z. After a bad power surge a few days ago, nothing was being displayed on any of the phones initially. Unit appeared to be cutting on (DC and AC leds were lit) however nothing. The AC led looked a bit dim. After some troubleshooting found the -55 V was not being detected on my meter and I found a blown fuse at F5 location and replaced. Now, phones come up and I get a display but when I try to pickup any handset, the dial tone sounds off as if there is some voltage on the line? Hard to explain but dialing a number just says 'invalid number and alot of static. Internally dialing to extensions work fine. Any ideas what this can be? Also, no calls are coming through externally(not ringing)I am not a phone tech but have some electronics repair background.

Thanks for any help given!
