When cooking the turntable does not rotate - also saw a tiny black spot rough to the touch inside the top of the oven.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door
switch or mount trouble can be caused by slamming the door or by
opening the door while it's cooking without hitting the Stop pad first.
There
are plastic mounts inside the microwave which hold the door switches
and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes
it's a broken tab on the switch holder, allowing the switch to rotate
just out of position. Other times, it's a broken tab on the switch
holder, allowing the switch to rotate just out of position. This tab
can be hard to see, since it is under the bottom edge of the switch.
One test that sometimes helps is to gently lift up on the door or
handle as you try to start it. If it works or tries to work, then it's
a door switch mount or door alignment issue.
We have critical safety & disassembly info (including a how-to video) at our site, linked here.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

The
first thing I would suggest is a hard reset. Unplug the unit for a
minute or so. Then plug it back in, set the clock and try again.
Let us know if the hard reset does not fix it.
If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.
If
it stops after 22 seconds, that means the controller has detected a
problem, usually a problem with the inverter or a bad magnetron.
If you do indeed have a problem, Since
it's less than one year old, it should be fully covered under warranty.
I'd suggest contacting the manufacturer to get it fixed free.
I would recommend that you contact your nearest Panasonic-authorized servicer.

If
it stops after 22 seconds, that means the controller has detected a
problem, usually a problem with the inverter or a bad magnetron.
Due to the lethal
voltages used and produced in inverters, I do not recommend that an
inexperienced person work on these.

Sounds like a short in the microwave circuit. One or more of the following four components has failed -
Transformer
Magnetron
Diode
Capacitor
Repair is not for the amateur, unless you know how to take things apart, and put them back together EXACTLY as the were found.
Parts are available on the Net, and you can get the P/N's off the old components to identify suppliers of the new ones.
Don't try and measure resistance of the diode. It's impedance is far too high to get a good reading. They're cheap anyway. Always replace the capacitor, they're cheap too. No way to test the magnetron, and the transformer is not easy to test either.

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.
The cost of the magnetron is about 95% of the cost of a microwave oven.
Most people don't, for this reason, replace the magnetron, they replace
the whole oven which is probably what you will end up doing.
There is a possibility that the circuit that provides power to the
magnetron is faulty and you need to take it apart, find the proper
electrical leads and test them with a volt meter. To do this you have
to remove it from its mounting and take it apart. It is a fairly
lengthy process however.
