    Here is my situation... First my system:
    TV - Samsung WS32V64N
    DVD-player - DV-454
    A really expensive SCART (gold-plated and stuff)

    My problem:
    Then I send RGB signals from my DVD or Digital Box I can't view it in 4:3. The TV always shows it in 4:3. Even if I set the TV to 4:3 it shows it in 16:9. But the moment I turn the DVD (or Digital Box) from RGB to normal Video 4:3 works again.
    I talked to the Samsung support and they said that it ahd something to do with the 8 pin on the scarts. Note that I have tested several scarts and it is always the same thing. Anyway... The support told me that the signal from my DVD/Digital Box told the TV to send it in 4:3.

    So... Anybody out there that can help me? Maby someone knows how to get into the service menu (I've heard that there is such a thing) on my TV?

    There is more than one way to tell a piece of gear that it should switch to 16:9. One method uses some data in the VBI (Vertical Blanking Interval) ; another is to use pin 8 (the SCART I/O switching pin) . Whereas a nominal 0 volts/12 volts indicates input or output, a mid-level nominal 6 volts indicates 16:9 - which is fine if the receiving equipment recognises this voltage as a WS indicator.
    I remember having to explain this to the person responsible for a BBC Engineering website a few years ago as they had omitted this function in their SCART FAQ.

    So is there any way to correct this for me so I get WS/full then it's supposed? I now know how to get into the service menu but I'm too afraid to change anything in there.

    You need to tell your DVD & $ky digbox to output 16:9 via their respective menus - as long as they are showing 16:9 material.
    They should then send the appropriate voltage out on pin* of their SCARTs.

    It doesn't matter. I can change between Wide, 4:3 (Pan&Scan) and 4:3 (Letterbox) on my DVD but it is still locked in 16:9 no matter what I choose. The only time it shows in 4:3 is then I DON'T use a RGB signal (Video or S-VHS).

    Maybe a new lead will do. It happened to my with the PS2 connected via RGB, but a different lead solved it.

    "lead"? What is that? Is that the metal the pins are made of?

    Maybe the word "lead" is wrong (I'm spanish). I mean a new cable.

    Nope. The cable is fine. I've tried three different SCART cables of different quality on both the DVD and Digital Box.
    Does anyone know anything that might help me out?

    I would put a voltmeter (DVM or analogue) on the DVD player when it is set to a 4:3 mode and see what I measured on pin 8 of the SCART.
    If this is beyond your technical capabilities (I am an electronics engineer myself so no problem myself) get a techie friend to do the measurement for you.
    If you're in the Manchester area , I'll do it for you.

    Well I live in Sweden so It's a long way to go to measure a pin ;)
    However I do know how to use a voltmeter... I think... I just have to get my hands on one. I'll check with my physics teacher on Monday. Maby you can you tell me what I should be looking for?
