Sony KDL 26S3000 NTSC to Europe's PAL

[Konstan]

Ok first of all let me say that i am new to this forums(as you propably noticed from 1st post :P)and im new to this whole thing of NTSC,PAL and video formats etc etc.
So here is my problem:
I lived in Los Angeles until recently where i bought my Sony KDL 26S3000.After moving to Greece i saw that my GF had a lame 20" Noname TV so i brought afterwards my TV also to install it there.I read the manual and TV was saying that it played from 120V-240V and 50hz/60hz.So what do i have to do to make the TV signal from antenna play properly?
Currently as video is concidered TV Chops the lower part of the channels and as audio is concidered you cant hear anything than "snow"(Dont really know the word for this its the buzzing sound it makes when you are seeing snow :P).

It would be great if a solution could be found without needing me to buy a new TV :<.Thanks in advance for your time guys.

you only have a u.s. atsc tuner in that tv, not the required pal secam tuner. you may be able to buy something like this to put between the antenna and tv.
