Re: black screen

If one of these solutions doesnt work you will most likely need to purchase a new calculator.

Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!

I have a casio calculator fx-350ES. My problem is that everything that appears on the screen is very bright, I can hardly see anything. Changing one battery did not help.

Press SHIFT 9 To clear and reset defaults.
Or Press SHIFT MODE to enter (Setup). Look for option <CONT>. That changes the screen CONTRAST.

TI 92 Turns on but has a black screen.

This is expected behavior when batteries are replaced and you don't need to reset the device, simply adjust the contrast more than you would think it should take.
See the answer to a similar question at When powered on the LCD screen is dark blue.

Calculator occasionally can be turned on, occasionally cannont. Batteries are perfectly fine, because I tried several times in switching them. Everything else with the calculator normal.

Either the ON button is sticky and hard to press or contact is not good (calculator may have been dropped and casing is loose)
OR you have to adjust the contrast of the screen.

To adjust contrast

  1. Press [2nd] key and release it.
  2. Press and HOLD [UPArrow] key to darken screen or [DownArrow] key to lighten.
  3. Release the Arrow keys when contrast is to your liking.

My screen is black and it wont go away how do i fix it?

The screen contrast of the TI83Plus/TI84Plus/TI84PLUS SE can be adjusted to suit the user. Sometimes after the batterie have been replaced the screen contrast is reset to the factory defaults.
To adjust it to your liking.
  1. Press the [2nd] key and release it.
  2. Press and hold the Down Arrow key to lighten the screen or the UP arrow to darken it.
In your case, the screen is too dark, so in step 2 above you press and hold the Down arrow until the screen lightens enough.
Hope it helps.

Screen fully black

Black-Screen/Black-Pixel Fix for TI-Calculator

This will erase all memory and reset defaults.

1. Remove 1 AAA Battery
2. Press and Hold 'ON' for 30 seconds
3. Replace AAA Battery
4. Adjust Contrast to appropriate level

If this fails, try again with ALL Batteries removed including
the backup Lithium Battery.

If all else fails, try the following reset procedure:

1. Remove ALL Batteries (inc. Backup)
2. Let Calculator sit with no batteries for 2~4 hours.
3. Hold 'ON' for 30 seconds.
4. Replace all the batteries (May be good idea to use new batteries
just in case old ones were dead)
5. Turn on Calculator
6. Change Contrast to appropriate level

- Remember to use correct batteries or calculator may not work. The
correct batteries are Alkaline, Rechargable Batteries are TOO WEAK,
Heavy Duty batteries are TOO STRONG.
