Hi, I'm Nathan.
Sorry to hear that you're having trouble with this but I'll do my best to help you.

Can you tell me more about the problem, is it just line 1 that isn't working?

If you plug the line 1 cord into the line 2 port on the panasonic, can the panasonic still access line*****(via L2) on the same wall jack/port you'd been using previously?

Customer: replied 11 months ago.
the 1/2 port is the one that wont work at all
Customer: replied 11 months ago.
my lines 1 and 2 are good... cable is good... is the port 1/2 not working
Expert:  Nathan replied 11 months ago.

So with L1 or L2 plugged into the l1/2 port (either individually or a combined line) you can still get nothing there?

You can get a response only from the L2 port?

port2 is good... i am using it
Customer: replied 11 months ago.

Yes, I'm here, my apologies for missing you. PLease try to send just a single message though, the site does not send replies instantly, but when you send multiple messages they get lost in the queue and further delayed, so I'm just now seeing all of these.

This symptom indicates a hardware failure in the base station, which is a bad relay/interface on the line 1 connection. We most often see this type of damage to the base unit as the result of a power surge, either through the phone or power lines, but it can be age related failure as well.

The one thing you may attempt yourself is to fully reset the system:
1) unplug both power and phone lines from the main base.
2) remove batteries from all handsets
3) wait at least 15 minutes, then restore all
4) place a handset on the main base for a minute, as if to charge
5) check for functionality.

If the problem persists after this, it tends to confirm a hardware failure which would require repairs to correct, though repairs for these units are not feasible as it will exceed the value of the system. Your best bet in that case is to buy a new unit with a base and a single handset (you can't buy just a base):

you can then pair your existing handsets to the new base and end up with a larger system. I can guide you through that process if you go this route.

Best regards, ***** ***** for the news,
