Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

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.

If this doesn't do it, please reply to this post and we'll go from there.

Every time you change batteries this will happen to you. First press 2nd then press and hold the down arrow. Hold until their is no black in the background but you can still see the numbers on the screen.

hi..

this may caused by internal errors. ICs in your calculator must have died.

i think your calculator meets its end of days.. how long you being using this calculator.

First, try adjusting the screen contrast. Turn the calculator on (or at least press the ON key). Hold down the C key and repeatedly press the + key to darken it.

If that doesn't do it, try reseting the calculator. Turn the calculator on. Hold down the C key and press the GTO key.

If that doesn't do it, use a thin pointed object (unfold a paper clip or use a sewing needle) and press the reset hole on the back of the calculator.

If that doesn't do it, the calculator may need servicing (or replacement).

Very likely that the screen contrast changed after the replacement of batteries.Some times screen becomes too dark or too dim.

If it does not seem to turn ON that may be because screen is too dim that you cannot see anything and cannot be sure it is ON.

To darken the screen:

How to do constant multiplication or division on the Canon P170-DH calculator

This process actually requires fewer keystrokes than other calculators. Basically, just do the first problem

and then do the next items with just the next number and the EQUAL key. For example,

*** Constant Multiplication ***

2 (multiply key)

10 (= key)

(The answer 20 shows on the screen. Note, the 2 is still stored as a constant without doing anything, just continue)

4 = (shows the answer 8 on the screen)

20 = (shows the answer 40 on the screen)

100 = (shows the answer 200 on the screen)

*** Constant Division ***

10 (divided by key)

2 =

(shows the answer 5 on the screen, the 2 is still stored as a constant without doing anything, just continue)

100 = (shows the answer 50 on the screen)

500 = (shows the answer 250 on the screen)

4 = (shows the answer 2 on the screen)

First try turning the calculator on and then pressing the 2nd key. Hold down the "up arrow". If the contrast has been turned down, this should turn it up.

If that doesn't work, could be that your calculator needs to be reset. Take out the internal battery located right above the 4 AAA batteries behind a small door with a screw. Leave all batteries out for about 8 hours. Reassemble and hopefully you can turn it on. If this doesn't work, you might replacing the internal battery. Hopefully one of these solutions will work.
