Listen Virginia,
I had fix similar problem too.
This is what you have to do.First you have to removed all screws (torque tipe) around the door, (inside)there is 8 srews;then the door will split in 3 parts (no worries).Inside the middle part there is a large black plastic cover;unsnap and removed.(this is the protection cover for computer circuit.Last step is unplug the large greay wire on the computer circuit, then turn the power on and then reconnect that cable while the power is on .this should reset the entire program you have done before,including favorite.The most important part is,note where all parts attched each other. Sorry about this vocabulary,I'm a french speaking and still learning that language. Good luck
