Question about Texas Instruments TI-83 Plus Calculator

3 Answers

WHen I replace the batteries, all I get is a solid black screen.

A week ago, I opened the case, and it said the ram was cleared, and now the only screen I can get is a solid black one, which I can sometimes get to go blank, and then when I turn it on, it shows the black screen and then immediately turns off.

Have you tried adjusting the contrast using second and the up and down arrows?

I found the solution on mathforum.com as well. What worked for me was doing a memory dump. Following are the instructions that I found: On 2006012917:15:08, silverHalo wrote: > > >One solution is doing a Memory Dump.

Hey, I had the same problem just now and found the solution on a math forum, the link is below. You probably already tried to adjust the contrast by holding down [2nd] and holding down [v] (=down arrow key). Instead try the following: Hold down [2nd] Hold down [v] Release [2nd] but not [v] and it will take the contrast back down to zero. What a relief, right? http://mathforum.org/t2t/discuss/message.taco?thread=1651&n=24

In this case the RAM may have the problem. Pl. do detach the RAM from the mother board and clean the golden contact points with a dust free eraser and re-attach the same to the mother board. (found under the back cover).
If problem persists replace the RAM with new.

The battery or the charger may be defective. Because it is so new I would advise you to either return it to the place of purchase or contact the manufacturer. If a defect surfaces within the first 30 days the manufacturer may require you to contact the seller first for any issues.

Black screen with blinking cursor in left corner.

Please power off, remove the RAM and then reinsert the RAM. Power on the pc.

P1493 code

If you are running any extra systems, ie amps, subs, high watt speakers, etc. etc. you may need to get a better batter, like the blue. or yellow top one. check with auto zone.

The cursor blinks as a checkered black square and keys don't work

The memory of the calculator is ful,l that is why you cannot enter anything anymore. You must clear the RAM of the calculator.
Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Press CLEAR to clear the Ram Cleared Message.
If that does not work, pull the main batteries out of calculator and leave them out for a while (a few hours). Then reinsert them.

Hope it helps.

Apple ibook crashed when on MS Word. Black screen fan running???

Sounds like you have a problem with the logic board. This appears to be a common problem with iBook G4 related to the fit of the logic board (ie motherboard) within the case.If you were to take it to apple store the likely fix would be to replace the entire logic board which is very expensive and probably not fiscally sound on a 5 year old machine. Another option would be to try to fix it yourself. If you are feeling brave you can dissemble the laptop and attempt to shimmy the logic board back into position.

Here's a link that detail the approach. http://www.coreyarnold.org/ibook/. This guy had success on two ibooks that had the same problem and they have been working for 2 years since he did his repair
Also, here is a link to a forum that may offer you a few more approaches to solving your problem. iBook G4 won't boot up - fan running & black screen - AppleNova Forums

Hope this helps, good luck!

Ti 83 black screen problem

i had the same problem. If you hit 2nd down 2nd down 2nd down and keep repeating untill the screen clears it should solve the problem. i tried the other solutions that tried clearing the memory and they didnt do anything but erase the equations i had previously put in it (great). But this should work.

TI-83 Plus Problem

Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!
