When I turn on my TV, a screensaver appears

This has been happening for the past 5 or 6 days.  I always turn my TV on and off using the TV remote (Samsung Series 6).  When I turn on the TV, I either get A) a screensaver, or B) X1 Tips and Tricks page.  All I have to do to get rid of the screensaver/tips is press play on the X1 remote.  The problem is....I can no longer rewind the program that the X1 box is turned to.  This has never happened before, like I said only for the past 5 days.  If I turn the box to a channel I want to watch and turn on the TV, say, at 6:25pm, I used to be able to say in the remote "restart show".....it would always quickly rewind to the start of the show, say 6pm.   Can no longer do this...it will no longer let me rewind, probably because of the screensaver/tips page.  Can this be fixed.....please.
