Apple TV not turning on Samsung TV
I know what the Apple Engineers need to change to make Siri Remote turn on a Samsung TV after being off for a long time ..
1) change the “On” small button on top right of Siri Remote to IR wake-up, not CEC = exactly like the Samsung Remote.
2) when the Samsung is off for a long time, it goes into “deep sleep” in which case, pressing the “ On” will not do anything when set to CEC wake-up. However, when set to IR wake-up, it will wake up the TV like the Samsung Remote.
3) given IR, the TV setting = CEC will turn on the ATV device
=> BINGO => Siri Remote turns on Samsung TV
