Toshiba Microwave display not working

When your Toshiba microwave display is not working, start with the control module. Press each control-panel button; if the buttons are unresponsive or do not respond correctly, the control module is likely defective and needs replacement. If your microwave does not use a separate display board, a failed touchpad and control panel can cause a blank screen or dark clock display. A display that is partially lit or missing segments more commonly points to a defective display board, while a screen that is completely out may be caused by either the display board or main control board. Also verify that the microwave has incoming power by testing the wall receptacle with another appliance and checking the circuit breaker. If the control board has power but the display remains off, the control board may need replacement. Enter your model number to find the exact Toshiba replacement part for your microwave. Any repair that requires opening the outer cabinet must be handled carefully. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged, so it must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician perform the repair.

05 - Incoming Power Problem

Confirm the microwave is plugged in and there is power at the wall receptacle. You can plug another small appliance into the receptacle to confirm there is power. If there is no power, confirm the circuit breaker has not tripped.
