How do you convert 220V 60 Hz to 220V 50 Hz?

well first off, the electronics in the tv rely on the 50 hz signal to get the clock going right to show the picture, so you'll have to get some sort of power converter, then the tv will only accept PAL signals. So as far as watching broadcasts, it wont recognize NTSC which is used in the US. so if you have a PAL DVD player or something you can watch that, but anything you plug into the TV must be PAL.
