      Hey all,

      I recently got an OSSC Pro with extra AV out etc as I wanted to use something a bit nicer to output to my Sony Trinitron.
      After receiving all the parts (OSSC Pro, Extra AV Out, AV Adapter 1.3), I tried setting it up and the best I can get is a garbled picture with interference. Picture is somewhat stable but has incorrect colours, dark and interference. I can’t even get a test pattern to display.  I have tried troubleshooting and am unable to figure out where the issue lies.

      My chain is as follows : Win11 HTPC -> HDMI -> OSSC PRO (running latest FW version) -> Extra AV Out -> VGA cable -> AV Adapter 1.3 -> Component -> Sony Trinitron XJ29M31
      To my knowledge the OSSC settings should be all set up correctly but also possible I may have missed something as I am not too familiar with the product yet.

      Let me know if you guys need further info/pictures.

      Thanks in advance.
