If the magnetron is OK,

DO NOT try to REPAIR this Inverter Power Supply (U) and also DO NOT RE-ADJUST PRESET VOLUME on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very large current. Off alignment or inverter board operation is dangerous. Operating a misaligned inverter circuit is dangerous due to the very high voltage and current that is produced by this board. Defective boards must be replaced with a new one.

The top right corner of my panasonic nn-h275 otr microwave door leaves a approx. 3cm gap when closed. Fixable? Dangerous?

If the door is warped cheaper to replace the whole oven, the 3cm gap is a hazard because you have dangerous radiation leakage, the levels are exceeding safety standards and should be removed from service immediately.

Our Panasonic NN-S763BF microwave turns on (light goes on, table turns and fan goes on) automatically when we open the door even though the clock is displayed. It works normally when the door is shut....

You have a faulty interlock switch (which the door operates).
This needs to be renewed by a qualified microwave service technician ASAP.
A potential hazard if not fixed immediately!

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
