Black and white games when using rgb

[SqUiDgY]

Ive deffinitely got the right scart cable and Iknow the TV is capable of playin imports as Ive used it in the past with my Ps1....... the only thing i can think of is that there could have been a prob when chippin - i didnt do this myself' is it possible to chip a machine wrongly so that it works for pal game backups but is b/w when playing import ones.. my chip is a neo 4 where i have to disc swap.

THX V MUCH EVERYONE
