Kay Fisher, director of program services at Channel 7 since 1970, has retired . . .

A veteran of 35 years at WJLA (she first joined the traffic department of WMAL radio when it was owned by the same company controlling the TV station), Fisher has been in charge of previewing, scripting or producing all public service announcements for WJLA . . .

She was honored at a luncheon at the Ritz-Carlton last week . . .

Also at Seven: Virginia Mielke, Emmy Award-winning public affairs producer, has left to become deputy press secretary for Rep. Michael Barnes (D-Md.), who is running for the U.S. Senate . . .

ABC now plans a total of 17 1/2 hours (including 13 in primetime) of coverage of the Statue of Liberty reopening ceremonies in early July . . .

The primetime programming starts with an hour special on Wednesday, July 2, and goes on to include all of primetime on Thursday, Friday and Sunday, as well as two hours on Saturday . . .

Syndicated film reviewers Gene Siskel and Roger Ebert are switching syndicators . . .

Last week they signed a five-year agreement with Disney Domestic Television after their current syndicators, Tribune Entertainment Co., apparently balked on raises (they reportedly made $125,000 each), because of a recent slip in the ratings for their "At the Movies" weekly show . . . now available to about 10 million TV homes a week . . .

The two Chicago-based reviewers reportedly also wanted to expand the format to include interviews and features . . .

The title "At the Movies" will remain with Tribune, which is seeking new hosts for the show. Disney will have to come up with a new title for the Siskel-Ebert program . . .

A couple of years ago, the duo had salary problems with their "Sneak Previews" series on PBS before moving on to sign with Tribune . . .

Organizers of the HBO special "Comic Relief" said yesterday that the show had raised an estimated $2 million to benefit the nation's homeless. The special, which ran more than four hours live on Saturday, was hosted by Billy Crystal, Whoopi Goldberg and Robin Williams. HBO will air a 90-minute edited version in April . . .

CBS' "As the World Turns" celebrates its 30th anniversary on the air Wednesday. At its debut, "As" was TV's first 30-minute soap opera . . .

An enterprising NBC affiliate in Salinas, Calif., dumped "Gimme a Break" and "Facts of Life" Saturday night in favor of a one-hour live debate among the four mayoral candidates from nearby Carmel . . . including Clint Eastwood . . .

Clint's early reviews weren't too good -- he apparently started a lot of responses with an "uh" and turned "parking spaces" into "parking splaces" at one point . . . but otherwise appeared to hold his own against the three opponents . . .

The KSBW debate anchor was so flummoxed by all the excitement, he forgot to permit opening statements from the contenders in the April 8 election . . .

There are a new producer and new writers for CBS' "Cagney & Lacey," in part because the old Emmy Award-winning team wanted more money . . .

"Miami Vice" is also getting new writers and a new production team in Miami. And both Don Johnson and Philip Michael Thomas reportedly want salary boosts. Johnson reportedly makes $30,000 to $35,000 an episode; Thomas, an estimated $25,000 to $30,000. We're talking 22 episodes a year, here . . .

Channel 7's locally produced "Changes of the Heart" special Wednesday finished second in the 8-to-9-p.m. time period with an 11.7 Nielsen count and a 19 percent audience share. "Fast Times" and a Charlie Brown special on WDVM averaged a 14.0/24, while "Highway to Heaven" on WRC did a 9.0/15 . . .

*On the Legal Front

CBS News reported yesterday that film and equipment seized from a "60 Minutes" crew last Friday as it filmed a protest by antinuclear pickets at a Missouri missile silo have been returned by federal authorities . . .

On Friday, according to CBS, "60 Minutes" correspondent Mike Wallace, producer Paul Fine and sound technician Craig Gibson were detained for about an hour at the Johnson County jail in Warrensburg, Mo., before being released with no charges filed against them . . .

The "60 Minutes" crew was filming protesters at two nuclear silo sites at Whiteman Air Force Base. Five protesters were arrested. An Air Force spokesman said they had cut fences, painted slogans and damaged an electrical outlet . . .

CBS News said the crew members were "covering a legitimate news story and were not charged with breaking any laws . . .

"Wallace and Fine had been filming as part of a story on antinuclear protesters who seek publicity for their cause by trespassing on federal facilities. Air Force personnel detained Wallace and Fine outside one such facility near Holden, Mo." . . .

Yesterday, a spokesman for CBS News in New York said while the film and equipment were returned Friday, the U.S. attorney in Kansas City is expected to issue a subpoena this week seeking the film, which reportedly would be examined for use as evidence against the protesters at the missile base . . .

TV game show producer Chuck Barris (who can ever forget Chuckles' "The Gong Show"?) has sued Telepictures Corp. for $5 million, claiming its "Perfect Match" game show copies his long-running "Newlywed Game" . . .

The suit, filed last week in a Los Angeles federal court, accuses Telepictures of infringing on Barris' copyright and also seeks to bar further broadcasts of the new show . . .

A Yale Law School student has filed a lawsuit against NBC because, he claims, the network minimized the danger AIDS presents to heterosexuals . . .

Arvind Shankar, a California doctor studying at Yale, filed the suit last week in a federal court because of a statement on the Jan. 21 "NBC Nightly News With Tom Brokaw" . . .

The broadcast said that a woman with a steady sexual partner, who was not in a high-risk AIDS group, was more likely to die in a car accident or be murdered than contract AIDS . . .

Shanker said such a woman's actual chances of contracting acquired immune deficiency syndrome are closer to one in 400, rather than one in a million, as he says the NBC program stated . . .

He asked the court to order NBC to either retract the statement during primetime or offer equal time to opposing views. He said NBC refused to grant him equal time . . .

NBC did not comment on the suit . . .

And actor Todd Bridges, who starred in the recently canceled "Diff'rent Strokes," was arrested Friday on suspicion of making two threats to bomb the property of a man he hired to customize his car . . .

He was released on $5,000 bond . . .

In 1983, Bridges was stopped by Beverly Hills police for speeding and running a red light in his Porsche. Officers found a loaded gun in the car. Bridges pleaded guilty to a misdemeanor count of carrying a loaded weapon and was fined $240 and placed on a year's probation . . .
