This will be either a faulty door interlock switch or High voltage component. You will need to remove the outer cover after first disconnecting power. Discharge the high voltage capactitor!
Check the door switches are operating correctly if so move on to the high voltage components starting with the transformer

The most likely repair is a blown fuse or circuit breaker, either to your mains plug, or in the microwave. Test by plugging it into a different circuit.
Beyond that, you would be looking at the power cord, then at the power supply circuit. If the clock is not at least displaying, you know it is probably not the controls. Go to Panasonic.com (or your local country equivalent) and click on Support, and you should be able to search for a user manual.

What does the start button have to do with opening the door?

No one can tell you without looking at it. You need to ask yourself how old is, what did you pay for item what does a new similar model cost, You can look at other brands = Ask yourself what do you cook in it, do you need all the features s and the size, Personally i would replace it.

Need more info like the model number which is printed on the back. It should also show the wattage on the same sticker.

If you can't find these and it was only a home microwave it was most likely only a 700 or 600 watt.

Well....the first thing you need to check is see if you have power going to your RY9 relay. If you do, there is a good chance the relay is bad (if you haven't already) If you don't have power going to that relay, you have to trace where the power is being lost. Fuses is usually a go to. According to the schematic there is an inductor in line with the netural line, check that. As well as an inductor with the lead, and several fuses.
