If your Gibson microwave display is not working, first check the control module. Press each control panel button. If the microwave buttons are unresponsive or none respond correctly, the control module likely needs replacement. On models without a separate display board, a defective touchpad and control panel can cause a microwave screen not working symptom. If only some segments are missing or the display is partially dark, the display board is the more likely failure. A completely blank microwave display can be caused by either the main control board or display board. Also confirm the microwave is plugged in and the wall receptacle has power by testing it with another small appliance, then check the circuit breaker. If the control board has power but the digital display remains dark, the control board may be defective. Enter your model number to find the exact replacement control module, touchpad, display board, or main control board for your Gibson microwave. Any repair requiring the outer cabinet to be opened must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Proper capacitor discharge is required before interior work, and a qualified technician should perform the repair if you are not familiar with that procedure.

06 - Gibson Microwave Control Board
Since the control board is a part of the digital display, a defective board could be responsible for a microwave display not working, if the control board has power to it but the display is not working replace the control board.
A microwave display not working may be due to a power outage or power surge. Full operation can sometimes be restored through a power reset by either unplugging the unit's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the microwave then switching it back on.
