There could be several reasons why your Panasonic microwave start button is not working:
1. Control Panel: Your microwave's control panel might be faulty. If your microwave is not responding to certain buttons, especially the start button, it might be due to the control panel.
2. Door Switch: Even if you firmly close the microwave door, a faulty door switch may prevent the microwave from starting.
3. Membrane Switch: This part of the microwave is touch-sensitive and can wear out over time or due to overuse, preventing the start button from working.
4. Touchpad: If your microwave's touchpad is faulty, it cannot send signals to start the microwave.
5. Main Control Board: The main control board might have failed thus it is not sending signals to start the microwave.
6. Thermal Fuse: A blown thermal fuse can also cause the start button to be unresponsive.
Regardless of the cause, it's best to have a professional appliance repair technician diagnose and repair the problem.

The turbo defrost is a feature on Panasonic inverter microwaves that allows for quick and efficient defrosting of frozen foods. It uses a combination of microwave power and the inverter technology to evenly defrost the food without cooking the edges or leaving parts still frozen. This feature helps to save time and ensures that the food is defrosted evenly, allowing for faster and more convenient meal preparation.
