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.

Does the tv make a clicking noise like its trying to turn on before the tv goes into standby and the LED starts flashing? I suspect this is due to a shorted component, most likely to be in the 5V(switching) line and just want to be a bit certain before we start testing the power supply.

If total dead best way is to follow the AC voltage from power cord inside the set to see where voltage is lost.

Also , were you having any problems having to turn set on several times to get it on?

Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.
