I have been looking for a solution to this problem for some time now. either its falling on deaf ears, no one cares or no one understands. So please read, and understand.
I upgraded to Quantum two years ago, No, I do not have the set top box numbers but that is irrelevant.
There is no current fix for this solution as this is a software issue you created by removing the function.
Under the old system we could disable the Screensaver so that when the box shut off after the preset time it would shut off and no signal was being sent to the television. This would then allow almost all TV's to turn off after 5 minutes. Why is this important? because most people leave their TV's on to go to sleep. My wife and mother-in-law included. (Much to my chagrin. I need totally darkness to sleep.)
My poor MIL has a hard enough time just getting the TV to work without complicating her life by trying to get her to use the other remote to set the TV to sleep mode. Which in itself is an issue, becasue sometimes you dont know you're going to passout in 21.2 minutes.
I wake up in the middle of night and have to shut the TV off because I have a large bright screen in my face. This is of course assumes I have the remote because my wife might have it. so now I’m waking her up getting up and fishing for it in the middle of the night so that I might sleep.
I have no idea why you removed this. I implore you. Please let us disable the screen saver, or even give the option to stop the signal to the TV after it goes to sleep for some time.
Every other system I have stops the signal, from my Xbox to my Apple TV
I promise you, I will never buy, or watch anything you display there, I never read the tips or even pay attention to them. It is a reminder of how much I hate it, of how much I am starting to hate FIOS, of the chunkiness of even having a cable box.. I am seriously thinking of getting rid of whole thing.
I need my sanity. Please fix this. Thank You.
