when I push on the soft keys nothing happens, the only message is PF when I first plug it in, the first time after I cleaned it the clock was working. Now nothing works. I disconnected the panel from the module by releasing
the tape wires with the little plastic restraints, I have no Idea why the whole thing stopped. I just wanted to clean the front panel, so I used a cleaner with a damp paper towel, nothing got wet inside !
