Handset doesn't charge battery or work
On returning from holiday the handset and charge base were on the floor having been knocked over by cleaners.
The handset doesn’t charge on the original base or any of the other 2 bases I have. The battery works normally however, in the other 2 handsets.
I have also tried tried my other 2 batteries in the dead handset with no result.
In summary all three batteries are in working order but none of them can operate the dead handset.
Is repair needed and/or possible?
