Hi all, long time ago, but now I need some help from the experts.
Recently, my TI83+ began acting weird. When I turned it on, it shifted my screen vertically. I could undo that by turning the calc off and back on, but a few days later, it began showing me random data on my screen. This went on for a few days, but each time I managed to get my calc somehow to work a bit.
But now I can't get rid of the random pixels on my screen. It still reacts on key-input - I can turn it on and off, and it reacts on menu-keys - but that's all it can do right now.
I allready tried installing a new rom, different versions of roms, leaving out the batteries, do the [Del] + batterie trick, but neither of them worked.
My question to you guys: does anyone know how to solve this. Any idea is good, there I really need the calculator and I don't want to spend money on bying a new one.
Note: I didn't do anything weird with it the last half year or so (like asm-programming), so I really don't know why it would do all this weird stuff  |

Have you tried MODE+ALPHA+S?
There have been problems like this before. Searching the forum should bring some of them up.
(Sorry I couldn't be of more help; I'm in a hurry right now). |

Oy! Until you said 'screen shifting' I thought this was a minor problem. Sometimes that can mean the display driver is running junk commands, but that's a very unlikely event. Here are a few general questions about your calc:
* How old is the calc?
* Has it ever been opened, dropped, or rained on?
* Running any ASM games lately? (Which ones?)
* What were you doing when it last crashed? |

Try taking all 5 batteries out and leaving the calculator like that for awhile. |

* Tt's about 2.5 years old
* It has been opened, a long time ago, but I never experienced problems until recently
* I haven't been running any asm games, except a flash-prog that I made myself, but it's harmless (I used it before for a long time without problems)
* Nothing, I just turned it on, thats the problem, I can't get things to work

Yes I tried, but gave up after a short time, but I'm gonna try it again, in a minute.

I'll do that today, 'cause I won't need it anyway.
I'll write the results this evening.... Thanks anyway
Edit:
I left out the batteries today, and for now, it functions properly again. But I don't thing it'll stay like this, but let's hope it does  Yay.

Did you ever reset all the memory? That's essentially what you are doing by leaving the batteries out, except going through menus is faster.
Reloading the OS wouldn't change some things, because it only erases the OS, not all the other data/junk in memory.
I think. |

Yep. Reloading the OS only clears the RAM in the 8x series. However with the 9x and Voyage 200 I'm pretty sure it clears RAM + ARC |

| clearing the memory doesn't clear all things, the OS is still there, and maybe some other stuff too. The only way to completely clear your FLASH rom is the self test, Mode + [S] trick. |
