SOURCE: i have put new batteries into my calculator after

The most likely cause is incorrectly placed batteries. (I know it from experience: It happened to me too).
Unlock the keyboard and remove it. Look at the polarity diagram on the body of the calculator, inside battery compartment. The positive terminals are towards the bottom.

To darken the screen press THE CTRL key and hold pressure. Press the + key until screen darkens.

Wont turn on


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. You are having problems because you calculator won't turn on. I think you should try changing the batteries. Did you know that your calculator has two batteries powering it? Not only are the 4 AAA batteries powering it, but there is also a CR 3V Lithium Back Up battery powering it as well. First, try changing the 4 AAA batteries. If that still does not power your calculator properly, you will need to replace the lithium back up battery. You can find this at a department store or store that carries electronics. To do this, open your regular battery compartment. Above the AAA batteries is a compartment that says "BACK UP BATTERY CR1616 OR CR1620" with a picture of it. Use a small crosshead screwdriver to open the compartment. Take the old battery out and replace it with the new one. Rescrew the lithium battery compartment back on and close the AAA battery compartment. Turn on your calculator and see if that works. I hope this solution solves this.

I haven't used my calculator in some time. Now when I go to use it, it won't turn on. I've pressed on and clear and reset. Nothing. It is solared powered and its not like I just change the...


If it is solar powered and hasn't been used in some time, the battery may have died, permanently. If there is no battery to replace then it is broken forever. Sorry.When batteries are left without juice for a long period of time they die, and cannot be recharged.

Won;t power up at all. New batteries but I did not replace back up battery. should I? Tried the contrast fix. Son said he dropped it and it got kicked down hall at school. One year old. Any hope?


Hello,

If new batteries did not solve the problem, the next thing to check would be the battery terminal.

If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.

If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.

If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.

If non of the above helps, then it means the calculator is dead and needs a replacement.

Regards.

Texas Instruments TI-30XA Calculator Problem


Either battery is dying, or circuit board has gone, or connector cable loose.

You can replace battery by removing 6 screws at back of calculator, but cost of battery is around 40% of buying new TI-30XA for $10 from Amazon, Staples or elsewhere.

I've used TI-30XA's for years, batteries usually last 2-3 years, then I buy new calculator. The one time I tried to replace battery, fading display still problem, so circuit board had gone bad.

So you could try battery replace and may be OK, but also may be waste of time and $$
