The season opener of "Magnum, P.I." completes the fall schedule for the three networks, but already CBS is beginning to tinker, moving "Frank's Place" to Monday before "Kate & Allie" and pushing "Everything's Relative" to Saturday. On PBS stations, look for several series openers, including "Nova," returning for the 15th season. Made-for-TV movies this week star Ann Jillian, Susan Lucci and Victoria Principal, all playing women with problems. And in the sports world, baseball playoffs begin, the Capitals get the ice hockey season under way, and the Redskins face St. Louis at RFK today. The networks' NFL games are tentative.

SUNDAY ST. LOUIS at REDSKINS at 1

21 JUMP STREET at 7 on 5 and 45

CASE OF THE MURDERED MADAM at 9 ON NBC

MISTRESS at 9 on CBS St. Louis comes to town to face the Redskins today at 1. WUSA may carry the game, but if it is not sold out, Washington may be blacked out. Watch that space. Fox Television's "21 Jump Street" concludes a two-part episode at 7 dealing with the murder of a 16-year-old drug dealer. The series, filmed in Vancouver, B.C., focuses on a youthful-looking undercover squad. Tonight, the officers infiltrate a high school to find the murderer, who may be a member of the squad itself. After the broadcast, the stations will carry a free 800-number. At 9, ABC's "Dolly" welcomes Whoopi Goldberg, Burt Reynolds and Alabama, while the competition carries made-for-TV movies. NBC's is another "Perry Mason" mystery featuring Ann Jillian as a former madam who is murdered when she attempts to use electronic surveillance to spy on a meeting of financiers planning a multimillion-dollar banking fraud. Vincent Baggetta plays Jillian's husband, with co-stars Ogden Stiers, Tony Geary, Bill Macy, John Rhys-Davies, Daphne Ashbrook and James Noble. CBS' "Mistress" stars Victoria Principal as Rae Colton, a former actress kept in lavish style by a rich contractor (Don Murray) who dies and leaves her bereft. Kerri Keane, Joanna Kearns, Alan Rachins and Guy Boyd all play friends of Colton. Series guests: Claire Trevor, Patrick McGoohan and Juliet Mills on "Murder, She Wrote" (8 on CBS).

Jean-Luc Picard (Patrick Stewart) at the helm of the Enterprise. The huge starship now carries families, and therefore includes schools and shopping centers. At 6:30, Channel 53 offers part two of its 13-part series called "A Better Mousetrap." The series, produced by Virginia Tech, focuses on scientific research. Tonight's program examines research conducted in cars, airplanes, homes and offices to find out what can be done to make life easier between humans and the machines they use.

(HBO subscribers will find the first half of another story about AIDS, "Intimate Contact," at 8, concluding Tuesday. This one stars Claire Bloom and Daniel Massey as a middle-aged married couple.) At 9, Susan Lucci leaves "All My Children" behind for a foray into prime-time, with John James of "Dynasty" as her co-star. In NBC's "Haunted by Her Past," Lucci stars as a devoted but repressed wife who becomes possessed by the century-old spirit of a murderess hanged for killing her lover.

At 10, Maryland Public Television stations begin "Oil," an eight-part series tracing the evolution of John D. Rockefeller's Standard Oil, parent of many of today's oil companies.
