Today I took that off and fitted an S-VHS cable and now have nice sharp black and white video.
I then fitted a mod chip and checked the eeprom and it's PAL and has no problems, changed region to NTSC and back and it's still black and white. (My TV can display NTSC anyway without issue, but thought it worth making sure)
I found a solder splash and removed that, tidied up the resistors near the AV socket (some where missing and my replacements were a bit wonky) replaced the crystal near the video chip all made no difference.
Is this likely a duff video chip or something else causing a B&W image as I don't want to attempt the chip until I'm a bit more sure that's what it is?
