How can I fix my base unit of my synergy 2150 phone?

I have a B.T. synergy cordless phone cosisting of a base unit and 3 phones,the 3 phones are constantly showing 'searching' and you cannot get a line out. I have tried deregeristing the phones and then reregeristing but to no avail, its as if the base station has stopped sending out a signal.I can't find anyone in yellow pages to take it for repair or test
