Sharp KB-6524PS no power
I've got the same model and the same problem. Inside the microwave the Noise Isolation transformer shows black carbon from arcing on both sides of the PCB, but only no one pin.
It looks like a short to me, but I'm not sure what to replace. It appears this might be a common problem.
Sharp R-CD2200M Microwave Maintenance Mode CC1,2,&3 magnetron hours exceeded.
If it shuts down it is faulty.
Take it in for professional repair. They are too dangerous to work on. There is 125,000 volts in the capacitor just waiting for you to get near it. The magnetron will make you blind in about 15 seconds and the core is a poisonous heavy metal. It is a $2,190.00 commercial microwave so worth getting repaired professionally. It must have earned its money.

Sharp Convection Microwave won't heat and turntable won't turn.
I typically find it is not door hinge issues but door switch issues, especially with sharp. You may heve a little movenent in the door hinge and that is allowing the door hook to move up and down on the plunger for a door switch that is probably a bit melted due to bad connections. If you check the door switches and look for any browning around the terminals where the wires push onto the switch you will probably find an overheated connectoion. Replace the bad switch and run better wires and better termninals to the new switch and it will probably be fine.

Probably only a 90 day warranty but you should have 1 year on parts. Check to see if it will void the part warranty if you open the unit. Or just take to authorized dealer. Sounds like the control board is out. This is part of the keyboard where you enter commands and also contains the clock. There are components on that board which can be replaced, but if it’s still got the warranty on that board you are entitled to a new one. Labor cost is not covered. Also, if you don’t currently use a spike protector on the power cord, please use one ongoing. This greatly reduces the chance of a repeat of the same problem even with another unit. Hope this helps you.
