Your pal system is sending 4.2mhz. Your TV just reverts back to the B/W standard. This is of course if you are using a NTSC TV.

lodbro Posted December 17, 2014 Author Share Posted December 17, 2014 i actually found the problem the problem was the colour adjustment wheel on the atari mainboard. i had tried this befor but the thing is that the wheel is incredible sensetive, only about 10% of is actually controlling colour and the rest is just black and white.
