I am trying to help my grandmother with a phone problem. I'm not
entirely sure what's going on (she's very confusing) but some
(possibly all) of the Caller ID displays on her home telephones are
garbled to the point where they're unreadable. I think it happened
after a thunderstorm where the electric went out. The phones work fine
except for the displays. It's on both the cordless and corded phones.

Is it at all possible that the storm would damage only the displays on
the phones but yet the phones still work fine otherwise? I can't be
sure, but I think even the cordless extension sets that aren't even
connected to the phone line have the garbled display. That seems
really strange to me.

Are the CID displays garbled ALL of the time or only when a call is
received?

it happened after a thunderstorm where the electric went out.

If the CID data is garbled when transmitted, but the phone LEDs are
otherwise OK, it is probably a problem with the line. If the displays
are permanently garbled, the phones are damaged. Good luck.

More likely the damage came in the power line.
