One of my handsets for Panasonic KX-TG7643 is not working.It only works as a speaker phone. It s approximately 2 years old. The other two handsets are working.

I would double check your phone cord. There is usually 2 jacks in the back of the fax machine. 1 is for Line, and 1 is for phone.
Your phone cord should be hooked up in the LINE jack that goes to the wall.
I would also double check your phone cord on another phone to make sure the cord is good.
If you look at the clear connector that you plug into your wall and fax machine, does it have 4 copper/gold color wires contacts imbedded in the clear plastic connector?

Another thing to try, if you fax machine has a Line and a Phone connector, try plugging in a phone in the PHONE connector. Then hook up another phone cord going from the LINE to the WALL jack.
If you get a dial tone on your Phone, then you know you have it connected correctly. If no dial tone, then I would go back to the phone cord.
check those things and get back to me and I will see if I can help you with more suggestions.
Good luck.

SOURCE: problems with handsets

Are they cordless phones?If they are they get there dial tone from the base.If there is a blinking red light on the hand sets they lost communication with the base.Check your user manual to see if you need to program them to the base.

SOURCE: No dial tone - I have to dial using the speaker phone

sounds as if this phone will need to paired with the base again.

SOURCE: Panasonic KX-T7433

These phones are digital proprietary telephones which means that they only work on panasonic telephone systems and not on normal analog lines. If you have a panasonic system the correct way is to plug the line into the " To Main Unit ", the handset into " Handset/Headset" and a normal analog phone into " To Tel ". If the wiring on the line jack was not done digitally the phone will also not work
