The power is just the same. The initial letter subscript
could signify the mounting position of the magnetron.

Generally speaking, light bulbs can be had from common sources such as department stores, home improvement stores, and hardware stores. Of course, I don't know much about what you'd call those places "down under and over a bit", but I'm sure the terms will translate well enough. *grin*

Hi Maria! I have the same problem. Suddenly on display appears "Lamp" message, but it works well. The intern light turn off. After some seconds the light turn on...

If your microwave oven doesn’t heat, you may have a problem with the high voltage diode or rectifier. This component helps provide the high voltage that powers the magnetron. The high voltage diode is located near the magnetron and the high voltage capacitor, so access will require removal of the cabinet. Disconnect the power and also discharge the high voltage capacitor to prevent an electrical shock. You can then test the diode for continuity with a multi-meter. Diodes are polarity specific and you should see low resistance with the meter leads in one direction and higher resistance when the meter leads are reversed. Most multi-meters will have a special setting for diodes or rectifiers. If the high voltage diode shows low resistance in both directions or shows no continuity at all, then it will need to be replaced. If you find the high voltage diode tests okay, then you will need to determine whether power is being supplied to the circuit. This is a high voltage circuit and further testing should only be performed by a qualified technician.

then call the dealer about your warranty

The alarm device is defective.

Could be control board and/or control malfunction

Does the light come on when you open the door? If it does, I would venture to guess that the keyboard is bad.
