And that looks like what everyone is telling you NOT to do. You are dragging the IR codes from the database into your macro. That is wrong. You need to hit the round red button at the top (macro recorder) and navigate to each page the commands are on the remote, then add them that way (alias).

And why are there such long delays in the macro? I have not had to use delays like that on equipment, in almost 15 years. Also where the delays are at makes no sense to me. TV power is usually the 1st command in a macro, since it usually does require a bit of time to boot up. Why would you place it at the end of the macro string?
Just doesn't look right to me. That's on top of the fact, that you are not alias your commands - which is most likely causing your problem.
