I went to my customers palace on Captiva Island this morning to troubleshoot line 1 not working. Line one wasn't working along with 2,3,4. Every phone was blinking "SET TIME AND DAY". It would not let me past the password. I set all passwords the same. I had to do a RAM clear and default the KSU to get the KSU operational. Has anyone else run across this before?? I do have return next week with my CID cheat-sheet to complete job. 60 miles each way for 5 more minutes of programming. Am I whining?? Sounds like it.

Sorry about the red frowny face. I'm not sure where that came from.

I've seen that with the KX-TD series of systems before, but usually got it cleared once an incoming call was received on a CID-equipped line. Since your line ports seemed to have been knocked silly, I am guessing that this would not have resolved your issue. After a clean default, if the system came back up working OK, you should be OK.

You might want to replace the memory support capacitor.

Sounds power or weather (lightning) related. I've only seen this type of behavior after a storm, etc...
Do you have a ups and lightning protection on the system?

No UPS but Panamax KSU Max and CO 4X4. I agree with a power issue. No lightning but on Captiva Island, the power is irregular. Thanks....
