I had the same problem with a bug in my display. I took the panel apart and put it all back togther as displayed. When I power it up I get the flashing 8's, but nothing works on the keypad. Any ideas?
You must clean the bottom rear edge of the LCD glass, both sides of the
"zebra" strip, and the contact area of the circuit board with high
grade (50% or better) isopropyl alcohol and a clean cloth.
I've attached a photo here, but if it doesn't show up well, you can find it at:
