Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.

if you want i will buy the tv from you

dont put the LCD neaer magnetic things like speaker or ampilifier......when the problems happend?

The amount of standyby power consumtion is minimal. The only way to turn it off completly is to disconnect the power from the TV. This will however increase your start up time when you want to use the TV.
