lcould not see the lights on the clock or temperature on the control panel

The parts came with no instructions, we started to take off , the front panel , finally took off the 4 screws under the panel, then the two small ends caps on either side. the only problem we had after being carefull to study the part as we took it off , was the ribbon strip, that stayed connected to the stove. after we tried to put all back together, the exhaust fan kept coming on. There are two small
holes that need to be aligned in the replacement part. also to get the strip out and back in you need to press and pull up on the small black notches on either of the strip.
