Hi All, I'm dealing with an MX-900 that is not displaying any text at all. The screen lights up and the buttons beep when I press them but no text shows up. I have tried both the "loader" procedure (mute+on and batteries in) and the restore to factory settings procedure (Listen+Enter for 5 seconds and then LCD button 4, then LCD button 5 and LCD button 5 again) but no text shows during any of this steps. Anybody have run into this before?
