I hope you can help me !
If it is not possible, to make a hard Rest - this unit can not be used anymore !
Use Case:
Menü -> Contrast : there you have a number e.g. 37
Pushing the button right beside the LCD, it decreases the contrast.
I thought, it will decrease and than again raise again.
But no, it decreases until zero, then the LCD is blanck, and it is unpossible to use this
unit anymore !
It seems the microprocessor is storing this value. Even removing the battery, the LCD ist still blank !
It seems, there is a Software failure !
Decreasing the Contrast means, you must give this unit back for warranty to the reseller, it is not possible to use it anymore.
A reset isn’t possible.
But you can try this to get the contrast back on LCD.
Please try these steps:
Hope this will help.
If it doesn’t work with these step, you can bring it back to shop where purchased for RMA REQUEST.
