Bumping this thread, check out what I found from the 01-05-1987 issue:
http://www.americanradiohistory.com/Archive-BC/BC%201987/BC-1987-01-05.pdfOn page 185, there is a flyer for the back-end syndicated run of
Press Your Luck, as distributed by Republic Pictures. Notice that it lists the package consisting of 130 half-hour episodes. Those are the ones that originally aired on CBS from 2/25/85-8/23/85. This was, of course, the attempt to bring the show over to first-run syndication, which apparently didn't work. They were also the first episodes that aired on USA from 1987-1988.
Reruns on USA Network proved to be even more successful, and more episodes were added. Thanks to several recently resurfaced non-GSN episodes on YouTube, I was able to determine during which years the 1986 and 1983 episodes began airing on USA: 1989 and 1992 respectively.
