        <li style=”text-align: left;”>I’m kind of lost on what to do, just got my new TV (Sony K65XR55B.CEI / aka Bravia 5 2025) and a PAL Gamecube which is confirmed working on a relatives old TV with composit input. The old scart adapter I have and a nintendo hdmi cable both also working as the OSSC shows input (AV1_RGBS 625-i 15.62kHz 50.00Hz) and the greyscale when testing. Now I get the GC startup noise and continuous audio from the TV but no video/just blackscreen

        Sounds like you’re trying to use a composite video cable, you must use an RGB cable with the OSSC.
