I am not entirely sure as to whether you mean a positive synonym for "screeched", or whether the word itself has any positive connotations. A positive connotation for the word "screeched" could be the fact that although it is a harsh and displeasing noise, it is often used in conjunction with excitement. For example: "Wow!" she screeched, suggests that she is pleased, or incredibly surprised, and therefor is shrieking to express the above emotions. A synonym for "screeched" I rather like is "caterwauled".
