I seated the ribbon cable better -- thanks...(and I think I put it in with the leds on the correct side) but I still get no llights or action. Could I have shorted something out....is there a switch I need to re-start things?

The water actuator on my door dispenser broke, and I undertook the replacement myself since a post on this forum seems to be fairly detailed.
Well I got the dispenser module out and replaced the actuator and reversed my
steps to re-assemble. The trickiest part (as I had read might be the case) was
re-attaching the cable ribbon between the module and the circuit board on the
door cover plate where you push the buttons to activate the ice/water. But I thought I did it all right.....now I get no lights on the display, no water OR ice
dispensed....seems like the electronics are not working....I definitely re-connected the wire plugs that were behind the dispenser module. Any ideas?
