In most cases, this is a problem with the inverter or a bad transfotmer. 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: http://www2.panasonic.com/webapp/wcs/stores/servlet/vServiceLocator?storeId=15001

When the high voltage capacitor fails, it almost always shorts, always resulting in a blown fuse.
Your problem is most likely a shorted / blown high voltage rectifier diode.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

To order parts, the best i can suggest is to call the number in your owner's manual or have a local appliance parts store match them up.

It looks like the metal part inside the oven is exposed to the high frequency rf waves. this may sound strange but try coating the metal part with fresh paint. remember no metal inside the oven will stand the waves created inside the oven the spark u see is the waves hitting the exposed metal part inside the oven

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it. YOUR
SAFETY IS PARAMOUNT This is a job for a professional but if
you are safety clued up, here's instruction.
Make sure the
!!!!capacitor is discharged!!!!! before attempting any
sort of repair.
Check the door interlock switches first then the
high voltage diode with either an AVO model 8 or moving coil meter on
high resistance range for short circuit, (DVM's won't show the
fault!), the capacitor can fail and go short circuit, the feed fuse
on the primary of the high voltage transformer and then finally, the
magnetron is best checked by substitution.
Hope that helps.
