Amiga 500 rolling picture

[Ral-Clan]

Hi thanks for the reply,

I am using a PAL amiga with RGB scart cable connected to a B&O TV. PC, game consoles work great both 50 and 60hz.

But with amiga the picture rolls.  But not so fast that I cant see the 1.3 hand and disk when turnin on Amiga. The actual picture is great, its problem is that it is scrolling.

I read somehwere that pin 12 is the sync signal from amiga port, perhaps contact problem somewhere.

Yeah, but did you try do adjust the vertical hold as suggested?  Some TVs will work great with a console but the vertical hold might just be out of tolerance for another device.

Also, what's a "B&O TV"?  Is that a brand name?

Is it possible to switch between NTSC and PAL in the early startup menu and see if that remedies the problem?

If your Amiga 500 has the Enhanced Chip Set, then you can get into the early startup menu to switch between PAL/NTSC by holding down both mouse buttons on power up.
