I turned the calculator on.. and the screen came on for a second and went blank. I thought it was a contrast matter so i changed the contrast level but nothing happened... so I bought new batteries. and replaced all of them.
but nothing happened either... I've never dropped the calculator or gave any shock....
plz help!!! I tried resetting as well with (-) button and ) button like the manual says...but nothing works so far...
Plz help!!!!! and thanks for reading |
