It is very common that the keypad rubber assy goes defective on these
types of phones, and remote controls as well. The conductive pads
start to wear out. Sometimes by cleaning the contacts under the pads,
the problem is fixed, but if the pads are bad, the fault will return
right away.

I think, this is not the problem, because all three buttons don't function
and go back to normal at the same time. I was more thinking of a solder
crack in the common of these three buttons.

I have no idea if Seimens will sell the keypad rubber as a replacement
part. Generaly these manufactures will tell you to send them the
phone for proper service. Many of the factory servicers also have a
flat rate service. You should enquire.

The problem is that (Sony)Ericsson (not Siemens) doesn't give any service
anymore on these types of DECT phones. So I would like to know how to
service this one myself.
Thanks anyway, giuseppe
