Question about Maytag MMV6178 Convection Microwave Oven
After removal of PCB, noted black spot on upper right corner of display part. Controller appears to work correctly; however, the display is black.
Well, assuming your connections are good on the board, and you;re getting about 3VAC on the filament leads (outermost two pins), I'd say you would need a new board assembly.
(The VFD tube is not available separately).
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
