In my work, I recently came across a couple of cordless phones packed away in a cupboard. I have been asked to see if they can be fixed (as my father is an electrician with experience in telephones).
I have not yet had a chance to look at all, but one that we're looking at right now is a Panasonic KX-TG2248 and when we plugged it in (to see if perhaps the only problem was that the batteries needed charging), the screen had an E3 on it and the charger light, the answer / on light and the play message / slow talk light are all blinking.
I'm searching now for possible solutions, so if anyone has any ideas, please feel free to let me know.
*Also I have not found the manual for the phone, so that makes it even more critical that I find another source for problem solving*

Try taking the battery pack to your local radio shack store. They can usually match the original battery pack with a new, compatible one even if they no longer make the EXACT one that came with the phone. This recently happened to me with a panasonic phone bought around 2002. phone stopped charging, no longer make the phone, etc. I went down to radio shack and they fixed me up with a new battery (not exact brand/part number as original) and it worked. Hope this helps you.
Unfortunately the EMI/RF interferances are a conflicting part of our day to day life.
Now you have this conflict of the wifi with your cordless to interfere.
So one option is to keep the base phone off to another location away from the wifi.
Move the antennae away from the strong signal pick up to lessen the interference. If porblem started recently it can be fault in the base unit changing. frequency
First try plugging the unit in and out a couple of times. If that doesn't fix the problem then check the battery packs on the phone units. BTW I meant to plug and unplug power to the base unit. If these solutions don't work then most probable cause is an audio component failure due to the voltage surge on power up. This is normally when most electronics will fail. Hope this helps.
Assuming you have DSL - Verify that you have a DSL filter in the phone line that leads to the base unit of the cordless phone.
Assuming your laptop connection is wireless - See if there is a frequency conflict with your wireless internet and the cordless phone.
If neither of these suggestions help, please reply with specific details regarding your internet connection (Cable/DSL) and the connection of the laptop
If the cordless phones are old 2.4GhZ phones, and you have wireless internet (which is probably also 2.4GhZ), the wi-fi could be messing with the phone signal/channel. Some cordless phones have a switch that allows you to switch channels. If so on your phone, try that.
This was happening to me, along with my internet connection dropping off every time the phone rang. So I went out and got a set of Dect 6.0 cordless phones, and the problem went away.
This method worked for me!! you guys should try this.
i've copy this review from amazon.

"After a brief power outage from a thunder storm, I also experienced an e3/lights blinking error. I unplugged the phone and plugged it back in several times to no avail. After doing this a couple of times unsuccessfully, I hit the "STOP" button on the base immediately after plugging it in (before it completed booting up to show the "e3 message")and it reset itself and now works fine (or as well as it did prior to the e3). Try it before tossing yours in the garbage"
I just had the same problem and tried several things with no results. Then, I figured I had tried everything else so I just unplugged the battery pack, set the phone down for 25 minutes and then plugged the pack back in. Phone worked again after that.
