Can't get numbers to display

I haven't used this in some time, so I replaced the battery and I cannot get the on/off button to work. It will only turn on when I press the AC key. When I do, no numbers will register on the display. It just stays as 0. What is not right here?

Re: Can't get numbers to display

Make sure there is not a key stuck in the depressed state. If so try to pull it back up and you should be set. If the machine had a liquid spill this could cause that type of error too. In which case the machine is junk.

Okay my TI-84 Plus silver is having some major issue. I can turn it on but that's it. The contrast is fine I can see the cursor. None of the other buttons besides the on button work. I've tried...

If a checkerboard cursor is displayed, then either you have
entered the maximum number of characters in a prompt, or memory
is full. If memory is full:

1. Press 2nd, then MEM, andthen 2 to display the MEMORY MANAGEMENT /
DELETE menu.

2. Select the type of data you want to delete, or select 1:All for a
list of all variables of all types. A screen is displayed listing each
variable of the type you selected and the number of bytes each
variable is using.

3. Press up-arrow and down-arrow to move the selection cursor next to the item
you want to delete, and then press DEL

If it is solar powered and hasn't been used in some time, the battery may have died, permanently. If there is no battery to replace then it is broken forever. Sorry.When batteries are left without juice for a long period of time they die, and cannot be recharged.

My screen for my TI-83 is turning black and I can't get it off

How to Change the Brightness of the Display

To darken the display, press the yellow 2nd button and then press and hold down the Up-Arrow button located in the upper right section of the keypad. Release the Up-Arrow button when the display has reached the desired level of darkness.

To lighten the display, press the yellow 2nd button and then press and hold down the Down-Arrow button. Release the Down-Arrow button when the display has reached the desired level of lightness.

As you go through this process, a number will appear at the top right corner of the display. If this number is 7 or higher when your screen reaches the desired level of brightness, then your batteries are getting low and may need replacing soon. This number will be approximately 3 or 4 for new batteries.

When I press ON, my calculator screen displays a couple random numbers and letters scattered across the screen, including a solid vertical line in the upper right corner. As soon as I push any key, the...

There are three possible solutions here. From what you are describing to me, you say the screen displays a couple of random numbers and letters, including a solid vertical line in the upper right corner, are scattered across the screen? Sounds like you are still in graphing mode. There is nothing wrong with your batteries and changing them won't help because I already know that you didn't change the CR Lithium Battery. This is the "memory card" for the TI-83 Plus. If you don't change that, when you insert new AAA batteries in the calculator, the memory has not been deleted. You probably don't remember, but the calculator remembers the last problem that you did, which was a graphing calculation. Try pressing the "Graph" button and the calculator will go back to function mode. If this doesn't work, try resetting all the memory.
  1. Remove a battery from the battery bay.
  2. Press and hold the CLEAR button while re-installing the battery.
  3. While still pressing the CLEAR key, press and hold down the ON button. If the home screen displays, release the keys.
  4. If the home screen is displayed, press 2nd MEMto display the memory menu.
  5. Select 7:Reset to display the "RAM ARCHIVE ALL" menu.
  6. Press the right arrow twice to display the "ALL" menu.
  7. Select 1:All Memory to display the "RESET MEMORY" menu.
  8. To proceed with the reset, select 2:Reset. The message "MEM cleared" is displayed on the home screen.
If this doesn't work, try changing the CR Lithium Battery. It is located in the battery bay at the top with the cross-head screw in it (It says BACK-UP BATTERY). It tells you what type of battery it takes and how to insert them in. I hope these possible solutions help. If all of them don't, then the only other thing I can think of is that it has some internal part alignment issues or a cold soldering iron blob, on the inside of the calculator. I saw one time on the Internet that cold soldering irons can sometimes make electronics not work properly.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...

The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

How do I change the date on a Sharp EL-1801V calculator?

Below is the step by step directions on how to update the date/time/tax rate. To set the date, time or tax rate, set the "Grand Total/Rate Setting Mode Selector (GT . RATE SET) to "RATE SET" position.
For Date:
1) Enter in the order of month, day and year, with the decimal point in between each set of numbers. Month 1-12, Day 1-31, Year: 2000 - 2999 (4-digits) or 00-99 (2-digits).
Example 04.10.2010
2) After the year, press the button with the clock/calendar symbol to complete the entry. When this button is pressed, the number entered is evaluated and displayed as "date" if the value is within the following range; "Error" is displayed otherwise, and the previously set date is restored.
For Time:
1) Enter in the order of hour, minutes with a decimal in between the hour and minutes, then press the button with the clock/calendar symbol to complete the entry. (No seconds value is entered) When this button is pressed, the number entered is evaluated and displayed as "time" if the value is within the following range; "Error" is displayed otherwise, and the previously set time is restored. Hours must be represented with 0-23 (24-hour system for the hour entry), Minute: 0-59.

FYI, This calculator uses CR-2032 lithium battery.

The calculator has an automatic power down (APD, a trademark of TI) feature that makes it turn itself off to save battery life. If you press the ON button, the last displayed screen is restored.

The calculator is intermittent: Most of the time

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.

Texas Instruments TI-30XA Calculator Problem

Either battery is dying, or circuit board has gone, or connector cable loose.

You can replace battery by removing 6 screws at back of calculator, but cost of battery is around 40% of buying new TI-30XA for $10 from Amazon, Staples or elsewhere.

I've used TI-30XA's for years, batteries usually last 2-3 years, then I buy new calculator. The one time I tried to replace battery, fading display still problem, so circuit board had gone bad.

So you could try battery replace and may be OK, but also may be waste of time and $$

On/off button does not work

The ac key is you power on key. As far as not being able to input any numbers, make sure there is not a key that is stuck down or depressed. if so try to lift is up and you should be ok. Unless there was a liquid spill. In that case, cheaper to buy a new one.
