Trang appeared in 80 episodes in the series , which included the entire first season and a portion of the second season . Trang performed many of her own stunts . She jogged and exercised regularly during her time on the show to stay in shape , and received training from martial arts experts on the set , including Jason David Frank . New to the acting profession , Trang said she learned a great deal during her time on the show : " I 'm finding that acting is all about being honest and truthful in every moment . The camera is so close that it sees everything , so if you 're truthful and honest , the audience will know . " She believed the show conveyed positive messages to children , particularly about teamwork and having self-confidence . Trang became close friends with co-star Amy Jo Johnson , and the two would often have slumber parties at each other 's houses . They were together when the 1994 Northridge earthquake struck , which badly frightened both women , but they were forced to go the filming that day anyway ; no scenes were ultimately shot because the crew did not arrive . Trang repeatedly got hurt on the set of the show , and often had to be physically carried by others during shooting because of injuries . Jason David Frank said of her injuries : " She put her all into the scenes , so sometimes things happen . " Trang left '' Power Rangers '' in the middle of the second season , along with fellow cast members Austin St. John and Walter Emanuel Jones , due to contractual and payment disputes . The actors were receiving nonunion pay , in the amount of about $ 60,000 per year without any compensation for merchandising for the show , which was estimated to be worth about $ 1 billion . Trang , St. John , and Jones were all represented by agent Ingrid Wang , and they requested more compensation . Amy Jo Johnson later expressed regret that she and the other cast members did not join the three departing cast members in calling for union wages , wondering if all of them standing together may have led to a different result . Within the show , the actors ' departure was explained by their characters being chosen as representatives in an international " Peace Conference " in Switzerland . Trang , St. John , and Jones released a joint statement about their departure : " Opposites Attract " , the 20th episode of season two , was the final '' Power Rangers '' episode in which Trang personally appeared ; her character appears in subsequent episodes , but only in costumed form and not portrayed by Trang . Trang 's character 's departure was explained in the two-part episode " The Power Transfer " , in which the powers of the Red , Black , and Yellow Rangers are transferred to new characters using the Sword of Light . Archival footage of John , Jones , and Trang were used in the episode . Trang was replaced as the Yellow Ranger by Karan Ashley , who was chosen from an audition process that included 4,000 actors in five cities seeking the three vacated roles . Jackie Marchand , a writer and producer with the series , said the departure of the three actors was " a difficult shift , and it was pretty intense at the office " . Margaret Loesch , president of Fox Children 's Network , released a statement about Trang and the other departing actors : " We will always consider them part of the '' Power Rangers '' family . " Trang said of her departure : " The show was great , it gave me a lot of experience ; but it 's time to move on , and I 'm focusing on doing feature films and becoming more serious of an actress . " On January 4 , 1995 , Trang and her '' Power Rangers '' co-stars St. John and Jones hosted an informational session about martial arts as the United States Capitol building in Washington , D.C. , where they taught basic techniques to Newt Gingrich and other members of the United States House of Representatives from the 104th United States Congress . Trang and St. John were interviewed on '' The Encyclopedia of Martial Arts '' , a 1995 documentary that explored the history of Asian martial arts and the role they have played in the Hollywood film industry . Trang made cameo appearances in martial arts videos made by St. John and Jones . Trang , St. John , and Jones also planned to unite for a live touring stage and arena show . She made a guest appearance at the Little Saigon Tet Festival in Westminster , California , on February 4 , 1995 , during which she spoke about her time on '' Power Rangers '' , other aspects of her career , and her experiences trying to break into film and television as an Asian-American actress
