in the inner side of the front panel there is a cable .that cable connects to the control panel to one end and to the main board on other end.if that cable is got short then the led will not display.but if the cable looks ok and not burned out.then remove the cable and reinsert and check out if still the same problem then.its time to replace the control panel board.
you can get required part from

if not familiar with this a local oven repair technician is advisable.
