yep, I suggested this too at first, but it doesn't react to buttons
(except power), hence the suspicion it turns off any image immediately
(which is confirmed by quick blink of some picture on power up).

Not anwering its own buttons seems like a bad sign. I imagine you've
tried any inputs other than VGA, but if not that'd be my next step.

 
As about blue / orange LED - thanks for hint, perhaps we'll figure out
what is what. It is blue when no video cable is attached and turns
orange on connecting VGA. But then after startup it again turns blue.
We'll see...

I've got four Dell monitors, the newest is over ten years old. All use
yellow LEDs for standby mode.

The behavior you describe is consistent with the monitor not seeing a
signal, though I'd expect to wait for at least a few mminutes before
closing up shop.

Good luck,
