    Hey everyone,

    first to say I’m still new to the OSSC scene. I recently bought a new model (HDMI) OSSC from eBay and it works so far. It has the firmware 0.82a preinstalled (does the a mean alpha…?)

    It works with my japanese PS2, my american XBOX Classic and the *normal* Scart cable of my japanese Sega Saturn. However after I try my newly purchased CSYNC Scart RGB cable from retrogamingcables, the OSSC only shows “no sync”. I tried to change what I could but it keeps telling me there is nothing. Some kind of error would be nice but just “no sync” is a bit… well… hard to google. I searched for two days now around and only found people having trouble with the image itself. Like strange line problems, wrong color or something, but not just “no sync”.

    I also read around here that the new firmware of 0.82 should have an auto switcher, but I couldn’t find it anywhere in the settings. I’m really confused as I am so happy to finally have everything to hook it up to my TV, but the OSSCs “no sync” gives me the headaches…

    The TV should manage any input. But when the OSSC keeps telling me this before it even gets into my HDTV, I don’t know what to do. Is this a wonky firmware? Did the seller something awkward to it? :S

    I recently bought a new model (HDMI) OSSC from eBay…

    Do keep in mind that you’re not going to get much support for your unit. The ones you find on eBay are going to be built poorly with cheap components, and you’re probably not going to find anyone who wants to work on it should something go wrong with the hardware. VGP, for example, is probably only going to be willing to do diagnosis/repair on units that they’ve manufactured and sold.

    It has the firmware 0.82a preinstalled (does the a mean alpha…?)

    No, the ‘a’ indicates that it has audio support. OSSCs prior to the 1.6 hardware revision didn’t have any audio support, and, while there was an audio addon board, it was only compatible with the 1.5 hardware revision.

    However after I try my newly purchased CSYNC Scart RGB cable from retrogamingcables, the OSSC only shows “no sync”. I tried to change what I could but it keeps telling me there is nothing. Some kind of error would be nice but just “no sync” is a bit… well… hard to google. I searched for two days now around and only found people having trouble with the image itself. Like strange line problems, wrong color or something, but not just “no sync”.

    First, unless you’re intending to connect your consoles to a device that absolutely requires clean composite sync (like an Extron RGB interface, or a PVM/BVM), and the console doesn’t natively output clean composite sync (neither the Xbox nor PS2 do), then there’s no need to buy a CSync cable, especially one with a built-in sync stripper–those generally cause more problems than they solve, although they generally don’t cause problems with the OSSC.

    Second, when using typical RGB SCART, the OSSC’s input should be set to AV1-RGBS; if you’ve got it set to AV1-RGsB or AV1-YPbPr, or any format on AV2 or AV3, then you’re not going to get sync because the OSSC isn’t looking at the correct sync line. If you’re on the correct input and you still don’t get sync, and the regular RGB SCART cables work fine like you said, then I would be inclined to say your Retro Gaming Cables cable is faulty.

    I also read around here that the new firmware of 0.82 should have an auto switcher, but I couldn’t find it anywhere in the settings.

    The manual is here: http://junkerhq.net/xrgb/index.php?title=OSSC. Take a look at the “Autodetect input” setting.

    Do keep in mind that it does stop checking inputs after a while, so if you’ve had the OSSC on with nothing connected to it for that period, you’ll either need to power cycle the OSSC or press the input button once.

    Only because it’s from eBay doesn’t imply it’s already a bad device. I got it from the platform, yes, but not from eBay.com but from “eBay Kleinanzeigen”, a place to sell stuff that is not really intended to be a bad china export. It also has everything that normally comes with it. The built is great too, and looks exactly like on any video / picture I saw so far.

    The device works in every other way expect for the CSYNC, so I wouldn’t want to ship my device around to get it repaired.

    …those generally cause more problems than they solve, although they generally don’t cause problems with the OSSC.

    That is my point too. I haven’t seen anyone having this side effect, so I was hopeing to get answers around here. 😉

    …and the console doesn’t natively output clean composite sync (neither the Xbox nor PS2 do)

    Well my japanese PS2 loves my RetroGamingCables CSYNC Cable very much and I get the cleanest picture out of it. My XBox uses the YpBpR input.

    Second, when using typical RGB SCART, the OSSC’s input should be set to AV1-RGBS; if you’ve got it set to AV1-RGsB or AV1-YPbPr, or any format on AV2 or AV3, then you’re not going to get sync because the OSSC isn’t looking at the correct sync line. If you’re on the correct input and you still don’t get sync, and the regular RGB SCART cables work fine like you said, then I would be inclined to say your Retro Gaming Cables cable is faulty.

    I know. Before I ask for help anywhere I first google for hours and try everything there is. I used every available input on my remote. As long as there’s no other input hidden somewhere, I tried it all. It does work with the normal Scart RGB cable, but this cable has a horrible audio buzz. The other only outputs sound on my regular TV but nothing on the OSSC. And I would really like to know why the OSSC outputs _nothing_. Something has to come through the cable. That is what bugs me.

    The manual is here: http://junkerhq.net/xrgb/index.php?title=OSSC. Take a look at the “Autodetect input” setting.

    Do keep in mind that it does stop checking inputs after a while, so if you’ve had the OSSC on with nothing connected to it for that period, you’ll either need to power cycle the OSSC or press the input button once.

    I’ve read the manual over several times, but I don’t have this specific “Autodetect input”. I’m also not waiting for the device before turning it on – I turn it on at the same time I turn on the rest of my devices. And even then I switch between the inputs just in case something takes longer to get detected.

    The complete lack of sync I think can only mean two things: either the cable is defective or your console has defective csync output.
    In general Saturn seems to have quite trouble free sync, but I guess you could still try some fiddling with sync settings, I think specifically threshold.

    You should contact RGC and check if you can get some troubleshooting help.
