Found an old TI-83 Plus

Hi!

Yesterday evening my wife found my old TI-83 Plus calculator in what seemed to be in good condition lying in a box up in the attic. I bought it in 2006, it was a requirement for the studies that I took at the time, but for various reasons it was barely used. Anyhow, she picked it up, flipped it over, and checked the condition of the AAA-batteries. Sure enough, they were quite old, but they hadn’t leaked all too bad. She decided to take it back to our apartment whereas I then carefully removed the old batteries, and checked the springs. They’re all in good condition.

Anyhow, this morning – whilst the calculator had been left without batteries overnight – I bought four new AAA-batteries and carefully put them in. (One can never be too careful, am I right?) I’ve ensured that the springs are working just fine and that the AAA-batteries are positioned properly. So I close it, flip it over down onto its back, place it down on the table, press the ON-button… and then this is happens.

I began googling for answers about this and found a few tips, so I’ve tried the following four suggestions:

Steps	Tip № 1	Tip № 2	Tip № 3	Tip № 4
Step № 1	Remove one AAA-battery.	Remove one AAA-battery.	Remove one AAA-battery.	Remove all AAA-batteries.
Step № 2	Press and hold the CLEAR-button for 5 seconds, and then release.	Press and hold the DEL-button for 5 seconds, and then release.	Press and hold the CLEAR-button.	Press and hold the ON-button for 30 seconds.
Step № 3	Reinsert the AAA-battery.	Reinsert the AAA-battery.	While holding down the CLEAR-button, reinsert the AAA-battery.	Reinsert all AAA-batteries.
Step № 4	Start the calculator by pressing the ON-button.	Start the calculator by pressing the ON-button.	Start the calculator by pressing the ON-button.	Start the calculator by pressing the ON-button.
Step № 5			The calculator should now display the following message: “RAM cleared.”
Step № 6			To remove this message, release the CLEAR-button and press the CLEAR-button one more time.

The display is acting up, the tips here above doesn’t seem to solve it, and I honestly don’t know how to tackle this. Where I’m from, this calculator still seems to cost quite a bit of money, so just throwing it away isn’t a decision that I’d immediately like to make. I could perhaps buy the necessary tools and open it up, but I’m really not a practical kind of guy. Besides, my wife’s really into highly advanced math whilst I, however, am not. Not even remotely. But I thought that getting this calculator up and running would make her really happy, and that it could aid her in the math studies.

Any ideas?
