i've realised that there are a few questions regarding whether to leave ur tv on standby or off at the main socket. i would personally recommend that it is switch off at the main. at standby mode, power is still being consumed. meaning that ur tv isn't actually off. the tv will alwiz be waiting for a 'on' signal for it wake up from standby. there has been many articles by both IET (formerly IEE) and IEEE on standby power. energy is being wasted in doing 'unproductive' work. there has been suggestion for standby features to be totally removed so that consumers are forced to switch off the power supply totally. by turning off ur tv or any electronics equipment, you are able to actually 'lengthen' the device's lifetime.
