Hopefully the setting might be kept somewhere in the system partition. Immediately after a restart with the cable with the good waveform EEPROM connected, dumping the partition to an image file on a PC, then repeating the process after a restart with the new screen then a binary compare of the two image files might give sufficient clues to locate what is changing or which waveform file is being read so a software fix can be developed.
If anyone has tried this previously, what was the conclusion?
Otherwise only Uber-Geeks with serial EEPROM programmers or SMD rework facilities are able to make a permanent repair. If you are doing more than just reading pre-packaged ebooks, you *DO* need to be able to restart when the system becomes unstable, and I certainly wouldn't want to open any of my Kindles every month.
