I have a TI83+. When I load an OS update the screen display is fine, when I use the device, the screen has strange characters, clearing the screen clears some parts and not others. The issues are not always with the same part of the screen so I don't believe the screen itself is faulty. Any ideas?

Depends on what the black screen is caused by. If you review others on this site some have come up with a methods of keep hitting the 2nd key and left arrow key repeatly w/ success. Just depends. Some had problems because of 3rd party downloads and had to reset and reinstall to clear things up. Some had to connect to the computer and use ti connect device explorer to delete and reinstall even the os software. I guess it just depends on how far you make it to solving the problem. I had them that I couldn't fix or figure out.

I suppose they can be replaced. You should contact the TI Consumer Support Department at [email protected]. They will be able to tell you where in your area of residence you can have the calculators serviced and how much It will cost you.
I have heard about a Casio program that gives credit towards the purchase of Casio calculators in exchange of TI calculators. Here is the link to the trade-in program.
I believe it is worth investigating this. You may end up replacing the calculators at a lower price. Casio calculators are very good and less expensive than the TI. You will be surprised to hear that Casio is the inventor of the LCD screen.

SOURCE: can you transfer ti83 os to ti 84?
The TI83Plus has the capability to transfer its OS to another handheld device. It is possible that the TI84Plus hardware will accept it. But why downgrade?. Why not resinstall the OS? The latest version 2.55MP is available on the TI website.
You say emphatically that you tried everything and maybe so, but I will ask you: Have tried to connect the calculator to a computer and explored its content with TI connect. You may retrieve some information about its status.
The TI connect software will allow you to transfer a version of the OS even if the calculator appears to refuse to turn ON (screen contrast problem.) If it cannot it will let you know.
Try again.
