Question about Panasonic KX-TG6700 Cordless Phone
Remove the base by taking out the five screws. Look for the ribbon cable on the left hand side. On each side of the cable is a little brown nub, pull away from the circuit board to release the tension. Pull the ribbon cable out, this will reset the circuit board. Put the ribbon cable back in and push the nubs towards the circuit board. This will add tension to the connection. Put the base back together using the 5 screws. Plug in your phone and you should be set.

I had the same problem - all the lights were on but the unit wasn't working. I called the local Panny service center and they told me it was either a bad ribbon cable or a bad circuit board. It's $35 to have them look at it and another $20 to replace the ribbon. If the circuit board is bad then you throw the phone away.
But I did get mine to work using the suggestion by Austin Ron with one modification. I removed the back and located the ribbon cable on the lower left side. (It's the only ribbon cable that I could see.) I pushed gently on the brown nubs to release the cable and then reattached it. But after I put it all back together it still didn't work. On the next try, I plugged in the power cord while I had the back cover off, played with the ribbon cable again and this time it reset itself. I then attached the phone line and got a dial tone. But now the phone only works with the cover off. Also, the buttons on the main base don't work and all operations have to be done through the handset. But, at least I can use it to make calls until I decide which phone to buy next.

Exact same situation as "crarycurt" (black marks on ribbon leads), and did the same thing. it reset, but ANSWER ON button was still frozen lit, and the phone nor the base worked would get a dial tone. i tried one more thing. I disconnected the ribbon on the other board (the one underneath, when you open up the back of the phone) and turned the ribbon around an inserted the each end into the opposite connector. now like "crarycurt" the base station seems dead the phone works! i'll take it. thanks all for the tips!

I had the same problem with my panasonic phone system. The brown ribben cable seems to be the issue. When I pulled mine I noticed there was black on the silver connectors. Perhaps this is the route of the problem or in the alternative this is where the heat melted some of the solder on the ribben end. Anyway pull the cable and both lines started to work but as soon as I put the unit back together the same problem appeared (all lights on and no dial tone) The solution seems to be that you need to plug the power chord in and then while the power chord is in you reattach the ribben cable. Not easy but doable. This seemed to work at getting the system back up and running however the base station buttons are all dead - BUT THE PHONES WORK!

I did what Austin Ron said, but before I put the base back together, I've plugged in the power cord and one phone line, while I had the back cover off. Immediately the phone "spoke" saying the line one was set. Then, I put the base back together, recharged the phone and the extensions and I was all set. Thanks Austin Ron and Jim Win.
