A checkerboard cursor indicates a full memory. Press 2ND MEM 2 to bring up the memory management editor, and start deleting unwanted items.

If that doesn't work, try a hard reset. Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Turn the calculator back on.

There is a cable called isotropic tape. It is a silver tape with lines in it that goes from the main circuit board to the display board. You have to open the calculator to see it. You have to carefully press on the contact areas between the tape and the circuit boards. The tape sometimes comes undone because of heat. YOU MUST BE STATICALLY GROUNDED TO OPEN THE CALCULATOR OR STATIC ELECTRICITY CAN DAMAGE CHIPS. I would highly reccomend using a microscope or magnifying glass when pressing on the tape contact areas. Do not press on the tape where there is no circuit to back up the tape or you can rip it! This may also fix the black screen problem which I sometimes had. Good luck.

My ti-84 silver edition calculator is not working at all. I have changed the batteries and the back up battery and still nothing but the black checkerboard square is on, it wont even let me turn off the...


If your calculator display the checkered cursor it means that the memory is full and you cannot type in anything. Clear the memory by resetting the calculator.
Press [2nd][Mem] then select [7:Reset]
Under the first Menu RAM select 1:RAM then 2: reset

The cursor blinks as a checkered black square and keys don't work


Hi,
The memory of the calculator is ful,l that is why you cannot enter anything anymore. You must clear the RAM of the calculator.
Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Press CLEAR to clear the Ram Cleared Message.
If that does not work, pull the main batteries out of calculator and leave them out for a while (a few hours). Then reinsert them.

Hope it helps.
Thank you for using FixYa and rating the solution.

There is a checkered box instead of the regular solid black box and it won't allow me to enter more than 5 digits. How do I fix it?


Hello,
The calculator is out of memory. All you have left is enough ram to hold the content of five digits.You can reset the RAM by pressing [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER][ENTER]. Press [CLEAR] to erase "Ram Cleared" message.
If you do not want to reset the whole RAm, you may proceed item by item, as follows.
  1. Press [2nd][MEM][2:Mem Mgmt/Del][1:All]
  2. You will see the list of the 6 lists L1-L6 (should be 12 B each)
  3. You see all apps, each with an sterirsk at the left (archived)
  4. You may also see programs archived or not
  5. Anything else should be deleted.
  6. To delete a non archived item, move the cursor to its line and press [DEL]. It disappears from the list.
  7. Do not remove too many large objets at the same time because the defragmenting of the RAM could hang the calculator.
  8. After removing a few items, press [2nd][Quit] to allow garbage collection, then restart the procedure to delete other objects.
Remember that many third party games and programs stay loaded in Ram even after having been terminated. These are the main culprits.

Hope it helps

There is a large black area in the upper left hand corner of the screen


If it is a square box, it is usually a text box. It can be fixed by turning closed captioning off. Either hit the CC button on the remote until off appears. Or go in to the menu find closed captioning or text and turn off. If it is not a defined box, it could be something inside the tv.

This may be because the closed caption bulletin board feature may be turned on. Go in to the user menu, and see how to turn off the closed captioning. You may need to refer to the user guide. If you need the closed captioning, you will have to find the proper mode to put it in.

e0df163.jpg does it look something like the example I gave? Anyways, I don't think that it can be fixed. and you can either:
A.) have the screen fixed (approx. $100)
B.) buy a new calculator (approx. $85)
( the monetary figures are approxamate and should not be taken literally, the $85 is at least what I last saw one for @ a Wal-Mart)
