If that is the only input on the back of your telly you might be out of luck connecting the VGA to it.
There are VGA to Scart cables but Scart to VGA isn't really a standard way of hooking up a PC to TV but it can be done, possibly , but depends on several factors.
You'd have to make sure the TV was set to RGB mode and not Svideo or composite. You'd have to make sure the VGA output was set no higher than 60Hz and the resolution might have to be 800x600.
Also PAL tv is interlaced scanning whereas a monitor is progressive scanning, your TV may simply not accept the input.
There might well be timing issues also as PAL tv's are not generally speaking compatible with a PC output .... I know you can use some graphics cards like the Ati Radeon with powerstrip tweaking software this but it's not something that's as straightforward as it might appear.
Have you no other connections on your TV?
