Page 1 of Black & white picture on Region 1 discs

I need help with my system, before it drives me totally up the wall.
I recently bought a Sony DAVS-800 player and surround system, which is very nice indeed. However, I bought it pre-chipped to be multi-region and while it plays region 1 discs, it does so in black & white.
I realise this is to do with NTSC playback, but I`ve tried everything I can think of to resolve this, but can`t. I am a bit of a newbie at this to be fair.
If I describe the set up, I would appreciate any ideas anyone may have to help me out.
As I said, I`ve got a chipped Sony DAVS-800 player which plays reg 1 discs, and seems to recognise that they its an NTSC disc, but there doesn`t seem to be anything in the manual/on screen instructions to change from PAL to NTSC (unless its an asian model, helpfully!). Am I missing something?
My TV is a Grundig (sorry, don`t know the make) 32" widescreen. It`s only about a year and a half old and not too cheap, so should be NTSC compatible. In fact it has got an option for this, which I am using, but it says NTSC 4.4. Does this mean it`s not a proper NTSC compatible set?
The connection I am using between this is an S-video to fully wired scart onto AV2. I don`t know if I need some sort of RGB adaptor (or if such a thing exsists), but there isn`t an RGB output on the player.
I`ve also got a PS2 going into this AV. Would this affect it. Doesn`t make a difference on PAL discs (only use the PS2 for games, not movies).
I`ve also tried out the player on the other two AV`s, with no success.
I admit I may be missing something very obvious, but any ideas would be great.
Cheers to anyone taking the time out to bother with me!

Could be a setting on your TV that you need to tweak (i.e. check which of the two SCART sockets is S-video compatible - one of them should be - then check your TV settings menus : you`ll probably need to configure one of your two SCARTs to accept an S-video signal - it won`t be set up this way by default).

For a thread explaining NTSC 4.4, see here: http://www.dvd.reviewer.co.uk/forums/thread.asp?Forum=211&Thread=124096&Type=1

If your Grundig has a true NTSC mode, you should use that. It looks as though your player is outputting true NTSC, which is at odds with how you`ve got your TV set up (it won`t be able to "see" the colour subcarrier).

Failing that, are you sure your player won`t output RGB? A fully wired (RGB) scart cable to an RGB scart connector on your TV is the only other way you`ll get colour on NTSC.
