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.

Chances are there are other bad parts blowing the diodes, most likely a MOSFET.

Also, the ESR of the electrolytic capacitors should be checked and all board connections must be checked and resoldered if suspect.

If you're not experienced in troubleshooting switched-mode power supplies (inverters) then you can probably save a lot of timer and money by replacing the whole inverter.

You can find the nearest spare parts supplier by selecting your country then the support links at Panasonic.net.
