    Hey guys, I need some help, this is more too europeans because its about a SCART cable but any help is welcome..
    I got a faulty SCART cable, dont show any picture on my tv and a very dark/unwatchable picture on other TV..
    I opened the SCART and this is what I got..
    [​IMG] maybe a capacitor broken?
    Another thing is that my cable have 4 capacitors and a resistor and all schematics I see have 3 capacitors and a resistor..
    Is this a full RGB SCART cable? Im only used to RCA to SCART adaptors..
    Thanks in advance..

    Is it an official cable? If not, what brand / where is it from? Have you tried it on another console? Is it a European console?

    This will more than likely be the cable being made poorly, so check your output signals are to spec for SCART.

    Looks like its intended purpose is to output composite sync with 15KHz RGB. If your TV does not support 15Khz - then no video output. As its wired .. not sure if it would work.

    Pins used in your photo; LEFT to RIGHT
    1) Ground
    2) Right Audio
    3) Left Audio
    4) +12V
    7) Mode Select 2
    10) Composite Sync
    14) Blue Out
    15) Green Out
    16) Red Out

    Here's a link for the Dreamcast A/V port and pin descriptions: Dreamcast AV Connector

    Here's a link to Dreamcast SCART pinout

    I'd recommend buying a Dreamcast SCART cable. I recommend thefoo.83 eBay seller. I have purchased several cables from them, custom made and very good quality. If you get one ... they have a very snug fit, make sure you insert all the way in.

    Thanks for the answer.. Yes I previous checked the pinout and came to the same conclusion..

    I didnt have a rca cable so I decided to transform this rgb scart cable to a normal scart composite cable and I managed to do it..

    In the dreamcast end I removed pin 4,7,10,15,16 and I gently switched pin 14 to 13 place where composite output is...

    In the scart end I removed the circuit board and I conected ground to ground, audio left to audio left, audio right to audio right and composite to composite..

    Now I have a working cable, not the best quality, but a working cable.. I already have a vga box...

    Many thanks for the replys
