Duplicating the original button press is the safest, most logical way to do it. I would not assume that one side of the remote button 'pad' is ground. It may be a grid like on a keyboard or it could possibly be a multi-plex circuit.

Marky_1979:
That sounds good I would still like to hear about these other options namely the ir blaster thing and this micro controller with usb option that was also mentioned they sound very interesting.

My main aim ultimately is to turn on the cab with one button and get the tv on the right channel and if needed change setting without having to cut into bezel or access the tv physically.
