Depending on the drink - you have probable contaminated the 'carbon' based contact points.

If you are able - take the calculator apart - and use some IPA (Iso Propol Alchohol) to clean thorougly - LINT FREE Cloth.

In fact - you will not do anymore harm by spraying / flooding the keyboard with IPA - and shake the calculator around left to right - this will free any contaminates.
Pour off the excess (which will include diluted contaminamte) -the IPA will evaporate within seconds - minute

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.


What do you mean by "changed the resolution"?

I would suggest putting it in some dry rice. That will soak up all the moisture. You might also try drying it with a hair dryer.

My TI-84 Plus Silver Edition stopped working


That actually is a result of water damage. You probably need to replace it, or see about getting it taken apart and dried if the water damage was recent. DO NOT take it apart yourself. Go somewhere and ask if that is possible.

I have a TI 84 plus silver edition. Won't turn


The problem may be due a screen that is too light to see anything on it. Adjust the screen darkness.
  1. Press [2nd] key and release it.
  2. Press and HOLD the [UpArrow] to draken screen.
  3. Release the [UpArrow] when screen is dark enough.
You can also connect it to the computer to see if TI Connect finds it. If it does, update the OS to version 2.53MP.

You change the backup battery if the calculator tells you RAM CLEARED each time you turn it ON.

You may need to reset calculator. Take ou the batteries and the backup battery. Leave them out for about 8 hours. Then put everything back in. Hopefully this will work.

Graphing calculator got coffee spilled on it


Your only hope is to open the case and wash out all the coffee with plain water. Don't forget to clean all the keys and switches under them. Dry and reassemble. This is a last chance procedure and may fail.
Don't spill liquids on electronic gadgets as the result is either much work or must replace.
