Power Timer-Didn’t Wake up to Standby

[birdman]

It is because I am not watching any Tv show at that time. Thanks

In terms of energy usage there's very little difference (if any) between On and Standby - the system is running for both.

So, if the box isn't indicating why it has been woken you could work around it by:

Set a Wake-up timer for 04:00.
Set a Go To Standby timer for 04:05.

It’s about keeping the Stb at a cooler condition so I could use it longer.
I try again. Thanks

It works now, thanks very much
