Why is the printing quality poor on my Casio DL-250LA(GYB) Calculator?
If your Casio Calculator's printing is poor, it could be due to a poor voltage VM, which should be 11V while printing. Another potential cause is a defective motor.
What to do if my Casio DL-250LA(GYB) Calculator has no display?
If your Casio Calculator displays nothing, it could be due to several reasons: * There might be no voltage at VF1 and VF2, so check VF1 and VF2. * There might be no digit signal or no segment signal, in this case, check the pulse signals from LSI. * The display tube itself might be defective, which you can determine if VF1, VF2, Digit, and Segment signals are okay.
Why is the display on my Casio DL-250LA(GYB) poor?
If your Casio Calculator's display is poor, it could be due to a defective LSI, short or open circuits between digit signals and segment signals (check between LSI and display tube), or a defective display tube.
