    Have you tried raising the contrast?

  • kakima May 28, 2011

    TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. Does it?

Having gone over two months without a response to my query, I assume my suggested contrast adjustment solved the problem.

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.

The base unit for my Philips VOIP3212S is not charging the phone I need to buy a replacement base unit. I put ordinary batteries in the phone and the base unit no longer works


Wilson - The phone was not made to use regular (AAA) batteries. Unless you install AAA NIMH rechargeables it will not work. Regular AAA batteries cannot be charged by the base unit.
In case you meant AAA NIMH batteries as "ordinary batteries" then your charger may be the problem, but I wouldn't assume that until I've taken a pencil eraser and vigorously cleaned the base contacts and tried the base again (with the right batteries.)
Good Luck, Mikeywaf

I have Model MDR-RF970R and the battery is not holding a charge. Where can I get another battery? The # on the battery is BP-HP550-11/2.4v 550mAh. Thanks. Joe


Sony has some special case they put around the original 2 batteries to hold them together.

You don't need to buy special batteries. You can put regular AAA NiMH in.

To remove the compartment cover on the headsets make sure you hold down the pressure button on the left headphone to release the cover. Mine has the words "PUSH" on them.


With the cover removed you can then see the original BP-HP550 sony battery. Which you can remove and put 2 regular AAA batteries in.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...


The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

Ti-84 problem!


Could be that your calculator needs to be reset. Take out the internal battery that is located in a tiny door with a screw right above the 4 AAA batteries. Leave this out for about 8 hours and put it back in. Put in the AAA batteries and the calculator will be reset and may work.

I bought a motorola Talkabout, a set of three, and only got 2 batteries.


I put three AAA bateries in it! I still think you should include batteries when you sell a product with rechargeable batteries that you can't buy anywhere!!!! So I wont be able to recharge the regular AAA batteries. Yeah I am still burning over the problem.!!!

It wont turn on


Well, you can either try another AAA battery, or buy the same MP3 from a different store.(Be careful, some stores stock defects of items, such as MP3's.)
