Won’t turn on using Apple TV Siri Remote

[userofkdnLkmdL]

After TV has been off for a long time, when I press the power button on Siri Remote, only the Apple TV will turn on but not the TV  

IF TV has been off only a short while, both turn on just fine. 

Only the Samsung Remote works for the above, but not the Apple TV Remote. 

Both the TV and the ATV are set with CEC on. The ATV preference for turning on TV with the Siri Remote is set = on.
