verizon digital 6.0 cordless phone 100 - one of the 4 phone/base (not main base) - phone shows it is charging in base, when removed from base - no display, no dial tone. When put back in base, does not make any noise, no base station flashing, it does show it is charging in the base, but when push buttons when phone is in base - again no dialtone, no noise when pushing buttons. did change the batteries and did not fix these problems.
