My personal suggestion would be to go for these repair catalogs. I know this website www.reliable-store that i used to get manuals from, and they have all models online.
I also brought for my 1989 BMW, such old model, they had it and it was very good manual. Go ahead, I bet.

Replace the h.v. capacitor (the silver can mounted in back under the magnatron) and the h.v. diode and it will be fine.

SOURCE: Panasonic Inverter NN-V673S microwave- shuts off after 2-30 secs

If the screen is showing a fault number or a number you havent seen before then its probably a program fault which can't be fixed. Check that the vent holes on the back of the oven aren't dirty and ensure that the whole oven is clean inside. Sadly it sounds like a program fault which cant usually be fixed by the owner though.
Finding a Panasonic oven repairer in the UK shouldnt be a problem though. My parents had a simlar problem wth their Panasonic Inverter oven, called the UK customer services and Panasonic contacted an authorised repairer in Scotland to visit them. Call customer services on 0844 844 3868.
If the call out charge exceeds £80 then you're probably better off buying a new oven.

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, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

SOURCE: My Panasonic Microwave Genius 1300W will not heat

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.

My panasonic will run for about six seconds and stops, and smells like burning wires and it shows a message "SENSOR RE-HEAT PRESS START"

If it stops after 7 seconds, it has a problem with the inverter.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor. But I don't think that's the issue here.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

You can find an authorized Panasonic servicer here.

How do I remove the sensor inverter on the Panasonic NN-S96OWA ?

That's a misnomer.

And oven may have an inverter and it may have a sensor (usually either a heat sensor or humidity sensor).

Panasonic Microwave NN-A770S getting hot on right side externally

If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.
