Please log in for more thread options 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. I think the displays on at least five phones are damaged. | |||||||||||||||||||||||||||||||||||||

I'd guess it doesn't work, either. Sounds like something's wrong with her wiring. But either way, you'll definitely get an answer by trying a known good phone in the house circuit. Good luck Chris | |||||||||||||||||||||||||||||||||||||

That sounds more like a phone company service issue.

Your phone in effect is picking noise that is screwing up the decoding or, the encoding of the CID signal is incorrect which should be a phone company issue in both cases. http://webpages.charter.net/jamie_5" | |||||||||||||||||||||||||||||||||||||

what is the audio quality of the phone like? If it is crackly, then water might have got into the phone line (they sometimes use airtight pipes to run the cables inside). This will mess up the caller id signal. I cannot imagine it is anything to do with the electronics of the caller ID chip. The front end of all phone circuits is quite high voltage with transient suppression on it, so should be fairly robust. As Chris suggested, either take a good phone to her house, or bring her phone to your house... Rgds Bill Electronworks.co.uk - electronic kits for education and fun > Mike S. wrote:
