Hi Guys maybe one of my fellow repairers has got some light to shed on my problem
Ok ps4 comes in with no hdmi signal. Port looks fine so immediately I suspect the hdmi ic.
changed that twice still no image. Ok maybe the chips are no good, So order new one, changed it. Still no picture. Changed all the hdmi filter chokes all read good continually. ok last shot then I’ll replace the hdmi port. Still no change. Test the fuse near the hdmi port ok. So I’m stumped, Funny thing is I had one like this years ago, same board sac-001 never could fix it! I know its just some little component somewhere in the hdmi circuit that probably just needs changing but which? anyone know?
