Stephen Collins -- Network Yanks '7th Heaven' From Schedule

Stephen Collins' confession he molested young girls is already causing collateral damage ... episodes of his most famous TV show, "7th Heaven" are being yanked off the air.

A rep for TV Guide Network -- which airs re-runs of the show -- tells TMZ the two episodes remaining on the schedule will not air -- nor will any future episodes of "7th Heaven."

We're told ... programming honchos dropped the hammer on the show ... after seeing our story that Collins was recorded during a therapy session ... confessing to acts of molestation years ago.
