    If you installed games and other internet programs, one of them may have caused that condition. Delete all that was not downloaded from the TI site.

I have horizontal lines across screen have to turn on couple times til it comes on voice will work but screen not on turn off on then pic an sound with lines across screen


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Try to reset everything to see if that helps. If it doesn't , you can try to upgrade your operating system on the calculator to see if that helps to make it go away.
If that doesn't help try this:
"Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message."
Let me know how it goes.

My screen has a horizontal line across the screen


Make the calculator perform a self test: Part of the test is the display of some line patterns. You will be able to see if something is wrong with the screen.

TO PERFORM A SELF TEST (No I am not shouting, but I cannot use Bold fonts nor underlined)
  1. Turn calculator ON
  2. Press and HOLD the ON key
  3. Press the "E" key , the key with an E to its right
  4. Release the ON key
  5. Tests will be performed cyclically until you execute a SYSTEM HALT
TO PERFORM A SYSTEM HALT
  1. Press and HOLD the ON key
  2. Press the and release the "C" key key with a "C" to its right.
  3. Release the ON key
  4. You should see the empty stack.
If you need to repair it, google FixThatCalc.
Good luck.

Blank lines across the screen of a TI-86 graphing calculator


Try this, hook up new battery and go to MODE and darken and lighten the screen.. do it ten to fifteen times. if that doesn't help, try hook up most left and most right's battery terminal to a DC supply at 4.5V. dont go above 4.5 it will fry your calc (it is design to handle 3V). now you are forcing extra juice into the dead LCD screen lines... and reapeat the MODE + darken trick. I fixed mine like that! Works! and remeber to leave it completely black(darkest) for a while to keep that dead line alive!
