Playing PSX back up with Messiah 2

[TRDragster]

I tried the NTSC fix colour, when i tried using the NTCS fix as shown in the Installation diagram of M2, the T.V. turned black and white when i tried ps1 back up I eventually disconnect the NTSC fix. I used the cable the comes with the ps2 when I bought it and donot have problems with PS2 DVD originals/back ups and ps2 cdr's before, BTW my ps2 is not working right now due to my laser( i think). The reason why I brought this question is if it's a good idea to just buy a new one and thinking that the messiah 2 being defective? I have a PS2 V5 U.S..

Thanks....
