Are you going to pay the monthly fees to leave a cell phone attached to your TV? Why would you want to control a TV anyway, for the neighbors?

Probably to make it look like someone is home. I sometimes do this with timers on lights, but the damned modern TVs won't come on with a simple timer on the power cord. Some do have programmable timers built into them.

Any decent 'modern' TV should, older sets used an extra pair of contacts on the on/off switch to bring it out of standby when you turn it on with the switch, and would only come on in standby if you switched the mains to the set.

But decent quality sets haven't done that for years now, they store the status of the set in EEPROM, so the set is restored to it's last status when the mains reappears.
