Sony 55X900E sleep screensaver problems

[sunnyryz]

Hi,

I have a new Android 4K TV 55X900E, Andorid 7, latest firmware. Most of the stuff works fine but there are two annoying problems: screensaver does not work, TV never goes into sleep mode. Changed any settings, made factory reset. Nothing helps.

also have this issue; can confirm it won’t work on “no signal” screen, only works on the apps menu, very poor design, hope sony can update firmware and solve this . No signal screen really not helping for avoiding burning LCD
