    Thx Morpheus for your reply and highlighting the corresponding traces.

    I checked the schematics already and figured out that indeed IOVDD is connected everywhere. Was hoping there was a likely culprit. The 12v probably triggered an over-voltage behind U5 which led to a short somewhere. ICs usually just fail without creating a short. Filtering caps usually just survive unless they are of the tantalum kind which short. Do we have tantalums anywhere on the board?

    Anyway, I’ll keep checking, thx.

    Btw. I got myself already a new OSSC but want to revive this one as well. One cannot have too many retro video converters 😉
