Blank lines When I turn my calculator on there are several horizontal blank lines on the screen, it makes it hard to see anything. I changed the batteries but nothing happened. Can this problem be fixed?

The leads to the screen have probably been broken by trauma (dropping), and can be repaired if you have a soldering iron, a steady hand, and don't mind voiding the warranty on your calculator by opening it. On the top and left of the screen (from the front) are the rows of leads into the screen. Close inspection should tell you which ones are broken, and solder should be placed over the broken area. The difficulty arises in that you cannot allow the solder to cross the leads, and so must use tiny amounts. A stereoscopic microscope comes in helpful for this procedure.

It sounds like the lcd is either defective or damaged by liquid spill or dropped. Not feasible to repair. John

Calculator not turning on

TI calculators have an annoying habit of dimming the screen when the batteries are changed so as to appear not to be turning on. Turn the calculator on (or at least press the ON button). Press and release the 2nd button, then press and release the up-arrow button. Repeat the process several times and see whether the screen darkens.

Black line appears and then screen goes blank

Your calculator is most likely fine electronically, but the contacts are being interrupted by contamination; it could be water or other fluid, dust, etc. The solution is to disassemble it completely and to rinse it out. Here are instructions for disassembling the TI-84 which should be similar.
http://www.instructables.com/id/Ti-84-Basic-Disassembly/
If there's water let dry completely before putting it back together. If pop, etc., rinse with isopropyl alcohol (99% alcohol) and let dry completely. The best thing is electronic contact cleaner, available in electronic, auto and hardware parts and supply stores and online. It must be 'safe for plastic' and 'non-conductive', and definitely NOT contain anything like ACETONE. These are harmless to electronics, and my be used to douse any device to clean up all types of contamination, including unseen carbon build-up from normal use. They dry quickly and leave no residue. They can be safely used in any other electronic device and to clean the contacts of old outlets, light switches, etc. -- anything with electronic contacts.
Try to rinse out all areas, especially where the screen makes contact with the main board. If there is any kind of crusty green build-up on the batter posts (due to battery acid corrosion), you may have to carefully rub this with a cloth until you see shiny metal.
Once you've rinsed all the available areas, let dry COMPLETELY (I place a blow dryer (low heat) next to drying parts for several hours to be sure) and put back together.

My screen is blue when ever i change my batteries, So I Press the 2nd button and make it lighter. But the pixels dont lighten all the way And when i go to some type of menu like for Zoom, there are...

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 TI 86 is 6 years old and I have taken careof it well.

Try pressing (lightly) on the bottom border below the screen. If there is no change, try the top. If there is still no change, the power for your LCD may have become disconnected or shorted. There are external displays for these calculators intended for overhead projectors. If your school has one, you could try hooking it up to make sure the calculator itself still works.

In either case, it would be better to purchase a new calculator.

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!

Horizontal lines obstructing the second half of the ti 83 calculator screen, anyone know repair tips?

I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.

Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.
