That one minute of "Young and the Restless" on Channel 9 that disappeared around 1 p.m. yesterday was due to a power outage. WDVM engineers quickly switched to the station's own power supply while Pepco worked on the problem . . .

After 11 nights, the alms talks at Channel 26 have raised $458,610 toward the 17-night goal of $650,000 on 9,168 pledges . . . Most productive program, pledgewise, so far: "Anne of Green Gables" . . .

"CBS Evening News With Dan Rather" won the weekly network news race with a 12.9 Nielsen rating and a 23 percent audience share, compared with a 12.4/22 for "NBC Nightly News With Tom Brokaw" and an 11.3/20 for "ABC World News Tonight With Peter Jennings" . . .

According to The TV Column With Captain Airwaves, NBC continues to close in on CBS, 201 straight weekly wins or no . . .

Information smuggled to the Captain yesterday in a plain manila envelope by NBC revealed that for the first 10 weeks of 1986, CBS leads with a 13.9/24, compared with a 12.8/22 for NBC and a 12.3/21 for ABC . . .

For the same period in 1984, CBS averaged a 14.8/25, ABC an 11.7/20 and NBC an 11.6/19 . . .

TV Column fans undoubtedly have already realized that in that two years, NBC has gained 1.2 ratings points and three share points, CBS has lost nine-tenths of a ratings point and one share point, while ABC has gained six-tenths of a ratings point and one share point . . .

The same plain manila envelope also contained the results of two polls. The first, conducted by Media General and AP in August 1984, asked viewers which network they would turn to in the event of a major story. Thirty percent of the respondents said CBS, 29 percent said ABC, 18 percent said NBC and 7 percent said CNN . . .

A similar poll conducted by (where's that envelope?) uh, NBC research in January of this year showed NBC and CBS both got 27 percent, ABC 26 percent and CNN 11 . . .

ABC wouldn't confirm yesterday, but the reliable TV Digest reported Monday that the network started a new round of firings last Friday . . .

The trade paper said 17 were let go from the public relations department, 18 from purchasing, seven from the print shop and two from affiliate relations, including Mario Cucinotta, vice president and director of the department . . .

Meanwhile, we've learned that over the next two or three years, the new Capital Cities/ABC Inc. management will eliminate most long-term contracts throughout the company, which now numbers about 12,500 employes -- right up to and including contracts for some top corporate executives (Dennis Swanson, just named president of ABC Sports, reportedly was not given a long-term contract) . . .

Two weeks ago, we reported that ABC News had notified its top people that most producers would no longer be given contracts . . .

The practice of throwing contracts around reportedly began at ABC during Fred Silverman's reign as president of ABC Entertainment. Insiders suggest that when ABC President Fred Pierce and, earlier, ABC Broadcast Group President Anthony Thomopoulos departed the company recently, they took the last major long-term contracts with them, except for the very top brass . . .

Which doesn't mean all contracts will be eliminated. As current pacts come up for renewal over the next couple of years, our sources say they'll be reviewed on a "case-by-case" basis. At the News division, for instance, some on-air talent and some senior producers will remain on contracts . . .

To the dismay of talent agents everywhere, the move saves money, eliminating considerable paper work and the administration thereof. And also gives top management more flexibility down the road should further cuts in middle management and up be called for . . . Also in the News

Wayne Rogers will sit in for a vacationing David Hartman on "Good Morning America" next week. This week, "GMA's" new field reporter, Denise Yamada, sat in for Joan Lunden. She's from ABC's Portland, Ore., affiliate KATU . . .

Post-Newsweek Stations have named Tina Galland as Washington bureau chief. Galland most recently was executive producer and host of the morning program on the Voice of America. She has also worked for Metromedia news and WRC radio here . . .

She replaces John Dimsdale . . .

Bob Chandler, the former CBS News executive who was recently brought aboard by NBC News to help shape up "American Almanac," has finally got a title: managing editor . . .

The conclusion of "Dress Gray" on NBC Monday night had a 19.0 national Nielsen average and a 30 percent audience share that was up from its Sunday night count (see below) and also good enough to win the 9 to 11 Monday championship . . .

"Between Two Women" on ABC averaged a 16.2/25 and the last two hours of the regular CBS lineup did a 15.9/24 (as the audiences for "Cagney & Lacey" at 10 p.m. went bye-bye) . . .

Which leads us effortlessly into a report that CBS has notified its affiliates that during the May sweeps 60 percent of the primetime fare will be original episodes . . . and that at 10 p.m. each night, a time slot critical to all stations as lead-in for their late local news programs, all shows will be original . . .

Affiliates for all three networks in recent years have complained that the networks concentrated too much on the mid-April conclusion of the "regular season" and haven't programmed enough blockbusters or original series episodes for the May sweeps -- the results of which local stations use to set future ad rates, right into the fall months . . .

Good news, U.S. Senate fans, from aggressive C-SPAN, the public affairs cable network . . .

Starting today, a separate C-SPAN channel will be opened on many cable systems around the country providing a free-of-charge audio feed from the Senate, as that august body begins a radio broadcast experiment (TV coverage begins June 1 for two weeks) of its proceedings . . .

C-SPAN staffers will identify the speakers as they are heard on the gavel-to-gavel coverage. And when the Senate isn't in session, the extra C-SPAN channel, broadcasting 24 hours a day, will provide classical music!! . . .

C-SPAN said yesterday that about 1 million of its 24 million cable subscribers will be able to receive the audio service . . . Locally, that includes cable service in Arlington, Prince William County, Fairfax County and on the Capitol Connection . . .

As part of her "Grassroots" political series on the "Today" show, Nancy Collins will interview Rep. Jack Kemp (R-N.Y.) on March 13. We understand there are lots of hard-hitting questions . . .

N.B., C.B.: She told me . . . TV Ratingzzzz

NBC, already conceded to be the winner of the regular season primetime race, which runs through April 20, was an easy winner last week with a 17.6 Nielsen average and a 28 percent share of the audience . . .

CBS was second with 15.2/24 and ABC had a 14.1/22 . . .
