Amiga 600 display issue

[jimmy_600]

I've posted before but unfortunately I wasn't able to get any solution to my problem. I have an Amiga 600 which I purchased second hand. The computer works fine apart from the fact that the display does not "sit" squarely on the TV screen. I have tried at least three different TV's with no improvement and following advice from my last post I changed the display frequency in the startup options with absolutely no noticeable improvement. I even checked the FM box inside the Amiga to see if the display could be tweaked in any way... stuck for ideas now - can anyone help?

I am in the UK and the TV's I am using and the Amiga are all PAL standard.

When I tried this it altered the picture quality but not the position of the picture.  The quality itself is fine, but the picture is misaligned so that the top quarter of the screen looks as if it has been shifted upwards, leaving the bottom of the picture a third of the way up the screen. :-?

I don't have an RGB monitor or modulator to try it with  :-(
