I tested with the older TV and as already presumed there's also no picture. Will now
- Do a final test with a "naked" Pi 4 (which presumably will not yield a picture as well)
- Resend the Pi to the place I bought it and ask for a repair/replacement

I finally found the reason for the behavior observed:

• The HDMI-output of the Raspy 3 got broken at some time in the past.
• The TV was not causing this.
• The HDMI-outputs of the newly bought Raspi 4 were and are not broken.
• The IR-receiver(!!!) soldered to the casing of the Raspi 4 however was causing the malfunctioning of the HDMI-outputs (no idea why). After removing it the HDMI pots both suddenly became operational.
• Unfortunately the malfunctioning of the Raspy 4 was identical with the thing that got broken on the Raspy 3, which made error analysis difficult and misleading. So it took its time...
  

But everything is OK now, thx for the help received!
