We do display segment and backlight repair here in the US, but if you're in Australia, you'll have to contact Sharp there. See link below.

If yours is a model R-350C, that's an Australian model, so you would probably have to contact Sharp Support in Australia here.

If yours is actually a model R-305C, then that's a US model and the supplemental service manual is here.

You can find helpful exploded views (and sometimes schematics) for most Sharp microwave models and order parts from the Sears Parts Direct Web site.

Once you know the part numbers needed, you may find better price or selection from Encompass here.

You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.

Sharp Microwave Display intermittently working. Most of the time can't see time or countdown.


Only way this can repaired is to replace the whole display. If the unit is still under warranty take it to your local Sharp Service Center.

Otherwise, it is more than likely beyond economical repair. If you can live with it as is and just use it for short reheating you'll be fine, but the display will not improve. It can also be a safety issue as you could accidentally put in too great a time and burn foo, or even yourself with the contents of the microwave.
