[sdiy] Troubleshooting broken Waldorf Microwave XT

[Jonathan Lutz]

Hey all, thanks for the info.  

To answer your question David (whether or not it is the LCD): It is an
LCD display but it seems like the whole unit is not getting power
because none of the LEDs are glowing either (such as power-on
indicator, etc).

Does this sound like a power supply issue or............??
