I know I checked this thread a couple times yesterday and I didn't see that you had posted. Sorry for my delayed response.

1 sec is too long. Make it 0.2 delays. You stated you added the delay AFTER the power off command in the macro. Delays go 1st and between commands in the macro but not after the last command.

If the TV power off button works and you have that button in your macro, it should work.

In the macros I would turn on/off the components in this order:cable box, then receiver, then TV.

And I think I would delete the "off" macro and completely re-record it to see if that makes a difference.

Would you post your Power On macro and also your Power Off macro?
