Display issues I replaced the batteries in my calculator, but it still only displays half of each number--everything else works fine.

Half of the display is only working, the problem is in the driver ic that drives the display, it is simply not cost effective to repair the item, further ahead to replace the calculator.

Resetting the calculator using the keyboardThe easiest reset is done from the keyboard. To reset the calculator, follow the procedures below in the order presented.

1. Press ON to turn off the calculator.
2. Press and hold [ - ] .
3. Press and release ON .
4. Release [ - ] .
5. The screen will display “Pr Error ”
6. The calculator will reset to the default settings, and the memory will be erased.

Not knowing what to do, I tried anything that could possibly help:

I installed fresh batteries and I pushed the reset button on the back of the calculator (Sharp EL-546L) and finally, it work all right after more than 5 years I own the calculator and where it did work correctly for 5 minutes. I tried the reset button in the past (long time ago) and it didn't work. This time it worked because, maybe, I've used fresh batteries.

This happens alot with calculators that have been in storage for a while, you can fix this by taking the batteries out and let it sit overnight.

Faulty LCD product replacement needed.

Try adjusting the brightness setting for the LCD screen by holding down the "on" key and pressing the "+" key at the same time to make your screen darker or the "-" key at the same time to make it darker.

Unscrew the six small screws on the back with a small phillips cross head screwdriver (an eye glass screwdriver works fine), then carefully prise off the back using a flat blade in the two slots at the top of the calculator.

Keep it upside down or the display will fall out!

You'll see the two 1.5 volt alkaline batteries there, GPA-76 type (flat, round) in mine. Ease them out carefully and replace them, positive side up.

Alternative battery codes (manufacturer dependent) L1154, AG13, GA13, AG76, GP76A, 675HR, LR1154, LR44 per battery web sites, maybe others.

Make sure batteries are seated and display is in its correct position, replace back cover and six screws.

Caveat 1 : You can buy the TI-30XA for about $10-$13 at Staples/Amazon, two batteries will set you back around $5-$7!! But they last a couple years even with heavy use. TI-36X and TI-30X IIS are better calculators and have solar cells as well.....but about twice the price at $17-$25.

Caveat 2: I had one of these where the display faded, replaced batteries, did nothing because circuit board or display was bad. So you could replace batteries and waste the time/money.

Hi,

The only solution which can be tried is replacing the battery.

Goodluck.

i would say new batteries or a new calculator.

not a battery you just have to replace the either the keypad or keyboard
