Is it bad to unplug your plasma television every night?

Answer 1

Not at all. Leaving a television on uses a significant amount of power. Leaving it on standby uses far less power but it still draws a current. Unplugging a television stops it using any power at all. The main stress on a television is during power up, but that is seen when changing from standby to operating. Plugging a television in so it will go to standby is far less stressful to the power supply and will cause no noticeable reduction of performance.

Not only will you save money on electricity, unplugging a television will also reduce carbon emissions so it's good for the environment too.
