I checked the cable, it was OK. Today, I replaced the very last capacitor that was still original (C30, international), and I replaced U3 (again). One of the last two things did the trick, the Mac booted. Thank you all for your suggestions! Now I just have a wobbly display. I will try to...

I replaced that already during the first round. But lacking other clues, I will perhaps replace it again.
