Hi All,
Thought I would join and share my solution, sorry to dig an old thread this was the first thread that described my issue.
I was having the same issue as described above and the 50/60hz made no difference( other then the normal speed and size).
Basically you need to switch the console from PAL to NTSC, to do this I used the details here gamesx*com/wiki/doku.php?id=av:sms2_av
Found the CXA1145P chip
Cut the grounding on the underside of pin 7
Soldered pin 7 to pin 12 - effectively setting it high at 5v
And that's it.
Hope this helps

That's interesting. No crystal needs to be changed as well?

Nope didn't change anything like that.
It's pretty weird as my tv handles pal, NTSC 3.?? + NTSC 4.43. It's was as though the console and tv couldn't agree.
Image is as good as can be expected for comp vid in both 50 and 60 hz.
