After some time, I connected my PS3 again via HDMI. My BV740-MKIII has SW 4.17
Before everything worked just fine, but now: I don't see the start-up screen anymore, but do hear sound. It also plays stored games, but no bluray's. I can't tell if the problem started after the upgrade to SW 4.17
Connected to another (Philips) LCD-tv, everything works ok.
Any solutions?!
