Re: PANASONIC KX-TD1232 CE - PBX hybrid - Dial tone problem

Nope...dry as a bone in there. Problem most likely caused by hard use over the last 20 years. Those cabinets don't owe me a dime, its been very stable for a very long time. We've got >50 terminals attached to those 2 KXTD1232s...

Interestingly, one power supply did fail, almost immediately after that, and being a live system, I had to improvise. I robbed a molex connector from an old KX-A46 (battery backup unit for the non 'd' KX-T1232), and wired it up to a couple of 12V DIN rail mounted industrial switching...

Re: PANASONIC KX-TD1232 CE - PBX hybrid - Dial tone problem

...just chiming in with THANKS. Had this EXACT issue in double KXTD1232 cabinets. Replaced U6, U7, and U8 (MC145503P) - actually removed the chips, and put in sockets, THEN put in the chips - and the system is as clear as a bell.

Thanks to Sententia for posting the sound file, and thanks to Emiliovilla for the excellent solution!

There are 2 Panasonic KXTD1232s in Atlanta with renewed leases on life.
