Just backlight on !


New member
My 634 Serial wont display any text, but the backlight is on. I would like to ask how to reset the LCD Display. The problem was happened after we changed the label slot sensor to Digital SFT10-3 sensor a few times and the LCD Display disappears, just left backlight but when we press the function key, it can function. My model is CFA634-TFH-KS
