In most cases, this is a problem with the inverter or a bad magnetron.
Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.
I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.

A microwave can be dead for many reasons.
It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.
If
the fuse is good, it may be an open thermostat or thermal cutout (TCO)
/ thermal fuse on or near the magnetron or on top of the cavity / body
of the oven.
If it goes dead for a while during or after cooking
then comes back on, the magnetron is probably overheating and causing
the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
When
checking thermostats, if it has a hood fan thermostat, that should read
open, as opposed to the others, which should read closed.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If
it goes dead or blows the breaker (or GFI) when you plug it in or open or close
the door, then there's a problem with a door switch or door switch
mount.
If it's intermittent or random, it may be a bad
connection, usually on the control board or a loose fuse holder, or
even an intermittent fuse.
You should do a continuity test on
the fuse while it's in the holder (with the microwave unplugged, of
course) then turn the fuse by hand or take it out and put it back in,
then test it again.
If you remove the fuse, then press the meter
leads against the ends, it can allow internal contact to be made and
make a bad fuse appear to be good.

SOURCE: Replacement light bulb for Panasonic NN-9853 Microwave
Hello, I also have a Panasonic Microwave ( model NN-S 564 or 574 ?) They are very similar.
I have just removed the outer cover 5 screws ( unplug of course ) and have located the bulb holder which is a white plastic component with two clips holding the globe, pull it out and remove the two spade clips connected to the globe. The globe will come away attached to a black plastic mount. Next........do the run around to find someone who sells it.
Perth has an authorized distributer/repairer in Myaree whose details I got from Panasonic. He may sell them. otherwise I will try a couple of specialist light globe suppliers I know....PROLAMPS in Belmont and one in BALCATTA whose name escapes me but I have been there before...Hope this helps others.

The problem I had experienced with the Door not opening easily will be resolved by removing the micowave oven top cover with a tamper proof torx head, replacing the door switch and reinstalling the top cover.

Be extra careful not to touch the electronics inside since you could get shocked:
First remove the cover by taking out 2 philips screws, and use a hammer and chisel to break off the 2 'unremovable' screws. With the oven upright, the bulb is accessed from above, under a plastic diamond-shaped part that has two wires attached to it. Use needle nose pliers to remove this part and replace the bulb.
