Preventing TV standby mode

There's no way to do this on most sets, Sony is the only I'm aware of that can remember it's previous state. Plug the TV into the wall and use it's power control. You could leave the cable box on all the time if you only want one power button, it likely only takes a 3 or 4 watts more whne it's on than when it's "off" which is really just standby.

Some TVs remember their last power on state (most Sonys), but most default to off after they've been unplugged. There's no way around this.

You should just leave the cable box on all the time. There's no reason to turn it off since they're internally always on. The power switch on most cable boxes just turns the switched AC outlet on and off and might mute the audio and video too. Andy Cuffe

I just found out Jensen TVs are made by Audiovox. They sure don't make themselves easy to find on the web under the name "Jensen". Not very customer-friendly.

Thanks for the responses.

Isn't Audiovox just another name slapped on Funai or Orion junk? Brands are all but meaningless anymore.

Use a remote control that can be programmed with "macros".

As previously suggested get a remote control with a macro function.

Other ways of doing this would be to get a learning remote control, butcher it for its innards and program a button to to turn on the TV.

Make a simple single shot trigger which triggers when the power is turned on to the set and use this to "press" the button on the remote hence turning on the television as soon as the power is applied.
