Hi,
On the mobo of my A3000 (rev 9, IIRC) there's a switch/ jumper that toggles between PAL & NTSC.
My A3000 has KS3.1 rom, and works OK with my Samsung Syncmaster 940B.
Just last week, i hooked up my A3000 to another Syncmaster (151S) and worked OK too. But when i tried to run an old demo (i forgot the name), it was out of sync with the LCD. Afterward, the Syncmaster 151 went out of order - it looked as if no dispaly, but when scrutinized closer there was actually a very dim display barely visible.
The switching of screenmode must have upset the LCD electronically :-(
I don't know if the 151S is still repairable or not....
