PacificState Posted March 18 Share Posted March 18 I have an 800XL I've installed a Sophia 2 into, which provides very good quality video with a DVI -> HDMI adapter. I also have an Open Source Scan Converter and wanted to check the AV output, so I bought a SCART cable from Cool Novelties on eBay (https://www.ebay.com/itm/325741116891), having been happy with their quality for other machines. Unfortunately, while the AV output sync is recognized by the OSSC (it shows a 60Hz signal), I just get a black screen accompanied by a slight buzzing noise. Does the Sophia need to be configured, or is there something else I should check on the hardware side? I have an NTSC machine. Thanks!

mimo Posted March 18 Share Posted March 18 I think the Sophia 2 needs to be configured , there is a utility for this as an atr file somewhere. I don't understand why you would want to do this though, output from Sophia 2 doesn't need any more processing Quote Link to comment Share on other sites More sharing options...
PacificState Posted March 18 Author Share Posted March 18 Thanks. It's not that I generally need AV out, but I have the machine open and I want to check it's fully working before closing it up again. I read the instructions and it seems like both outputs should work by default, but I'll try the configuration tool. Quote Link to comment Share on other sites More sharing options...
mimo Posted March 18 Share Posted March 18 https://www.thebrewingacademy.net/TBA_Sophia.zip there is a pin out and some other details here if it helps Quote Link to comment Share on other sites More sharing options...

As you have DVI output working my guess would be the cable or the OSSC that is the issue Quote Link to comment Share on other sites More sharing options...
PacificState Posted March 18 Author Share Posted March 18 Thanks - the OSSC works fine with other SCART cables on that input. I've mailed them, and while there's no reference on the eBay page I wonder if I need to apply the S-Video mod? Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted March 18 Share Posted March 18 I would always hook up chroma on any stock 800xl by default for colour svideo. (Mod not required for 800xlf's (ones with Freddie chip) as they have chroma already. Chroma hook up is dead easy. Quote Link to comment Share on other sites More sharing options...
PacificState Posted March 18 Author Share Posted March 18 I actually suspect I do need the mod, reading the topic on here. Will try that tonight! Quote Link to comment Share on other sites More sharing options...
