Hi,

I am trying to repair a Panasonic cordless DECT handset which was accidently dropped.

The handset was in-tact but there was a rattling sound coming from the mini-speaker and nothing could be heard from it.

So, I replaced the mini-speaker with another similar one but now all I hear is a buzzing noise when I press the on-hook button instead of the dial-tone.

All other functionality of the handset seems to be working fine?
