Casio FX-890P display failure - Johnny Shek - 04-03-2015 10:29 AM
A brand-new Casio FX-890P was acquired in Japan in 2004 and was only switched on in a few occasions. In recent days, I find that the screen can't show anything after the calculator turns on. After pressing the P button and the ALL RESET button, the screen suddenly turns black with all pixels on and sometimes blinks but still cannot work properly. After pressing the CALC button and typing BEEP, I can hear the beep sound.
Does anyone have the same problem? How can it be solved?
Thanks a lot.
