    The flat cable that connects the 2 PCBs on a 407 motherboard is very short and pulled.
    Unfortunately I cannot insert a longer flat cable because the connector is soldered on the VICII PCB!
    Then the video image on the component output is fringed for about 1 minute initially and then disappears.
    Often if you turn off the C64 and then turn it back on there is only the CVBS / SVideo output but the image does not appear on the Component output.
    Trying to turn on a few times again, the RGB image reappears.
    I also tried to change the power supply on the C64 and monitors.
    I purchased the kit on August 6, 2020.
    I am a little frustrated.
    Sorry for my bad English
    Best Regards

    I’m not familiar with that model of C64 “sixtyclone”. Maybe we should state that it is incompatible.

    It is not a different model of Commodore 64, it is a project that is on Tindie (Sixtyclone) and is a 1:1 clone of motherboard assy no.250407.
    MOS ICs are original Commodore ones and other components are new and more reliable.
    When placed on an original Commodore assy 250407 motherboard the ‘C64 Video Enanced’ behaves the same and the flat cable is always short!

    I would consider asking on the “Commodore 64/128” facebook group – I know I’ve come across a few posts where people successfully installed the component mod into a SixtyClone board. For example, here is a picture I just found on facebook group of someone with same model board sixtyclone 250407 and working component mod:

    Looks like their cable is routed differently, or maybe their cable was longer? Maybe they made a longer cable. I noticed in facebook picture one end of the ribbon cable has a grey connector where both of yours are black. Not sure if thats an indication they made their own cable.

    OK it’s good.
    I will try to change the VICII as well. But in S-Video it works perfectly.
    In any case, the problem of the short cable remains because the connector on the VICII adapter is soldered.
    I read in another thread that they send 1 short cable + 1 long cable but I only got the short cable.
    Thanks for the reply!
    Regards

    You are right, I opened my C64 shortboard 250469 and didn’t realize the ribbon cable connector is soldered directly to the VIC-II adapter and not in a socket, like it is on the RF modulator. Maybe because of the height constraints of the 250469 board – any taller and it would hit the keyboard above. Not sure if its possible to open the connector to replace with a longer cable.

    I re-read facebook post, that image I shared above is NOT the VGP kit – the user on facebook built it himself from c0pperdragon’s plans.

    It is not possible to ‘open’ the connector because the clips are close to the PCB. You should break off the top clip and replace with another clip. Or I have another solution: I have some PCBs that go under the VIC II they were made by c0pperdragon GitHub project. I have to assemble a new one and put a longer flat cable in it.

    Exactly, it’s not a VGP realization

    Thanks for your interest in this thread!
