Screen does not display complete numbers


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.

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.

88883888 this is diplay if i press all 8 numbers on hp10bii. What could be wrong? Perhaps week batteries? Please help


While it could be weak batteries, and that is a good start, it sounds like the LCD display is becoming "unbonded" from the flexible circuit that powers it. If you feel comfortable with electronics, you could carefully open the calculator and push on the flex circuit (looks like a thin piece of flexible plastic) where it attaches to the LCD display. Use a soft object such as a pencil eraser to do this.

FIX APPEARS IN THE SCREEN


Hello,
The display mode is set to FIX display format. You can change it to some other mode like SCIentific aor ENGineering. But you will have SCI or ENG on the screen. But why bother? These symbols are designed to remind you (if you need reminding) of the calculation and display modes your calculator is set to. It is not a defect.
Hope it helps.

Hi i have a problem with my Hp10bII calculator everytime i tried to calculate N3 I/YR5 PV-100 PMT0 FV should 115.76 but in my calculator gives me 101.26


101.26 is what you'd get for 5% APR compounded monthly for three months. 115.76 is what you'd get for 5% APR compounded yearly for three years. Make sure that the compounding interval and the interest rate are consistent.
