I've a Panasonic NN-651W microwave. One fine day it stopped working. Even no signs of power to the unit although the power is there in the plug. Shown the piece to an engineer and he said the problem is in front end PCB due to power fluctuation. Please let me know I can get a new PCB online or is it possible to repair the front end PCB.
There si a place called encompass parts that is a distributor for Panasonic, Look them up or call them with your model number and check price and availibility on the PCB

The 22 seconds is the giveaway.
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.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.
You can order Panasonic parts from Tritronics.

SOURCE: microwave dead even though power works
It sounds like the magnetron overheated and opened the thermal fuse on the magnetron.
This can be caused when
the internal cooling fan is not running or by a magnetron that is
failing.
When I say internal
cooling fan, I do not mean the hood vent exhaust fan which you can turn
on and off manually.
I'm instead talking
about the internal fan which comes on automatically whenever you
microwave.
It is vital that the
cooling fan runs, or the magnetron will be destroyed.
There
should be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very
helpful
when troubleshooting & testing.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
You can also find
helpful exploded view diagrams and order parts by entering your full
model number here.
The magnetron will have a 5 to 9 year warranty. Your manual will tell you that.
You can download GE
owner's manuals and installation instructions here.
If needed, GE may send
you a replacement magnetron. GE Customer Service is here.
