Getting a display of “Calibrating the Keyboard, don’t the keys” message on the display. Tested the buttons & all work. I replaced the 3 keyboards circuit boards.
Still the same fault.
Does anybody have a clue where is the fault coming from? The display, keyboard or the main board?
Any help would be greatfull.
Thanks, Larry
Each of those keys has a thin metal plate on the underside. If that plate comes loose, it can mess up the calibration process. So that would be the first thing to check. If the metal plate is dangling or has come off completely, it is easy to glue it back onto the key.
I have checked the ribbon cable between the keyboard and the mainboard- had 3 connections that was faulty- I replaced the cable , the keyboard now works.
