Funeral services were pending Wednesday for Chris Robinson, a longtime fixture of daytime television best known for his role as Dr. Rick Webber on “General Hospital,” and for delivering the line “I’m not a doctor, but I play one on TV” in an iconic commercial.

Robinson died Monday in his sleep at his ranch near Sedona, Arizona, according to actor MJ Allen. He was 86.

“He had been in heart failure for some time, and (that) is his official cause of death,” Allen said in a Facebook post Monday. Allen co-starred with Robinson in the 2022 independent film, “Just for a Week.”

With a career spanning more than 100 film and television credits, Robinson became a familiar face to soap opera audiences over decades.

Robinson launched his acting career in the 1960s with guest roles on numerous television shows, including “Sea Hunt,” “Death Valley Days,” “77 Sunset Strip,” “Gunsmoke” and “The Fugitive.”

In 1967, he landed his first regular series role as Sgt. Alexander “Sandy” Komansky during seasons 2 and 3 of the ABC military drama “12 O’Clock High.”

He went on to appear in a string of guest roles on shows such as “The Man from U.N.C.L.E.,” “Hogan’s Heroes,” “Medical Center” and “Barnaby Jones.”

Robinson joined ABC’s “General Hospital” in 1978 as Dr. Rick Webber. His character became part of a dramatic love quadrangle involving his wife Dr. Lesley Webber, Dr. Monica Quartermaine and Monica’s husband Alan Quartermaine.

During his time on “General Hospital,” Robinson appeared in a series of commercials for Vicks Formula 44 cough syrup, delivering the now-iconic line: “I’m not a doctor, but I play one on TV.” The phrase quickly entered pop culture lore and became a frequent punchline on late-night talk shows.

Robinson also had roles on “The Bold and the Beautiful” as Jack Hamilton, and “Another World” as Jason Frame. His final acting credit came in 2022 with “Just for a Week.”

Born on Nov. 5, 1938, in West Palm Beach, Florida, Robinson developed an early interest in acting. As a teenager, he landed roles in low-budget films, playing a juvenile delinquent in “The Diary of a High School Bride” and, perhaps more memorably, a spider monster in “Beast From Haunted Cave,” for which he designed the creature costume himself.

Other big screen credits included “The Young Savages” and “Birdman of Alcatraz,” both starring Burt Lancaster.

Robinson is survived by his wife of 14 years, Jacquie; sons Shane, Coby, Christian, Taylor, Christopher Robinson, Christopher Lance and Robb Walker; and five grandchildren.
