DSc545 LCD caibration

[Jomama46]

I talked this customer thru calibrating the LCD and he reports that it only holds the calibration for a a few minutes to an hour or so.
Does anyone know if there is a memory device on the PWB LCD for this calibration? Or are you familiar with this problem?
I see there is a NVRAM on the Controller and also a EEPROM on the BCU.

Hi Al, new firmware:
When the machine recovers from Energy Saver mode, the LCD turns black and none of the keys or buttons on the operation panel work.

Thanks for the reply, Paul, this doesnt seem to be the case, it s just that they have to press below the icon to engage the function.
Still it is a good thought and I will flash the firmware.
Thanks again.
