One last thing I can think of to try.
Do a cold init on box.
It will remove any custom settings, but doesn't remove any recorded content.
Nada. DId this on two boxes. Woke up this morning to the floating screensaver. I get it that they are trying to save my tv screen but if there's no signal on the hdmi line then why go into screensaver.
I had one more post to try that didn't appear.
It may be CEC settings.
Try this on STB:
Look under menu settings audio/video video settings TV input control. Set it to disabled.
Also look in TV options to see if there is setting for CEC.
On my Samsung it is called AnyNet. Description says it can power down device when TV is turned off.
I had high hopes for that one but alas the end result is the same. I too have a Samsung and see the settings you mention but this morning I still see the screensaver. I do very much appreciate all of your efforts.
And it is happening on two different TVs?
Are the STBs the same model?
I have 3 samsungs and none of them have this issue.
VMS1100 on a Panasonic - screensaver activates overnight. Not sure how many hours it takes.
IPC1100 on a 1 year old Samsung - screensaver activates overnight. Not sure how many hours it takes.
IPC1100 on a 1 year old Vizio - screensaver does NOT activate. Just realized this one.
CEC is turned off on the Samsung/Visio. The Panasonic is so old it doesn't have any smart features.
I respect your sticktoitivness.
This one has me intrigued.
Try swapping the ipcs.
Will help determine if TV or stb related.
Finally got around to this. Swapped the two boxes and the screensaver stays with the Samsung. The stb that used to be on the Samsung is now on a vizio and no screensaver. The stb that was on the vizio with no screensaver is now on the Samsung with the screensave. So, at least for the IPC's they don't show the screensave on the Vizio, but does on the Samsung. The main DVR, who knows.
So its obviously a Samsung interaction.
Maybe try reaching out to Samsung support?
They may know of a CEC issue with that model.
I assume you have checked for latest software updates?
