pal 1002 model rgb scart issue with NTSC games

Post by a7mag3ddon » December 10th, 2020, 6:32 am

Can anyone help or advise what i can do about a 1002 model PAL ps1?

When i try and play ntsc games using an rgb scart cable the screen blanks on and off all the time and is black and white.

I uploaded a video here : https://youtu.be/chqIhI3v0sg

The same cable and game works fine on a 7502 and a 7002 model psx on the same tv.

I bought an OSSC upscaler thinking that would fix and condition the signal but all i get on that is a blank screen and audio playing, thats on pass through as well which i thought would be black and white.

I have been reading about an oscilator mod to make it PAL60 but i am unable to purchase in UK however if it fixes it i would order from US or AUS and wait fo it.

As always many thanks for read8ng.
