I cant do anything on my calculator.....when i turn it on it says "waiting... please install calculator software now." When i press the "on" key, it says, "ERROR! Press any key to turn the unit off. Then turn unit back on." I've tried to remove the batteries and everything, but nothing will help it. Any advise would be greatly appreciated. I try to install the OS with the OS Downloader and it always says Connection Transfer Error

I am inserting a copy of an earlier post to a question similar to yours. . Please read the post till the end.
Part A may actually solve your problem.

A Try this before thinking of repairs.

1. Push the ON button.
   
2. Even if you see nothing, press the [2nd] key and release it.
3. Press and HOLD the UpArrow key until the screen darkens.
4. You may have to keep pressing UpArrow for a little while before you see anything.

B If that does not work

1. Remove one of the AAA batteries.
   
2. Press and hold the [CLEAR] key.
   
3. While holding [CLEAR], reinsert the AAA battery and then
   
4. turn the calculator on.
   
5. The calculator should display the message "RAM Cleared".
   
6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".

C. Third option

1. Remove batteries including the backup battery for 5minutes.
   
2. After the 5 minute period, reinsert all of the batteries and
   
3. turn the calculator on.
   
4. Adjust the contrast if necessary.

D. Last option

The last option requires the reinstallation of the system. So to use it you must download the TIConnect 1.6 software from education.ti.com. You must have the TI USB SilverLink or the TI Black serial cable ready.You must be connected to the Internet.

1. Remove one of the AAA batteries.
   
2. Press and hold the [DEL] key.
   
3. While holding [DEL], reinsert the AAA battery and then
   
4. turn the calculator on.
   
5. The calculator should display "Waiting...Please install calculator software now".
6. Connect the TI Connectivity cable between the computer and the calculator.
7. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OS Downloader.
8. Follow the on-screen directions to reinstall the calculator's OS.

If the message "Error! Press any key to turn unit off. Then turn unit back on." appears on the graphing calculator, quickly, remove one battery from the calculator and reinstall it while the transfer is taking place.

You have several ways to connect the calculator

• Serial Black cable that used to ship with the TI 83 Plus. It connects to a serial port on a computer and to the I/O port on the calculator. It requires the Graph Link software available on the TI web site (Downloads, Software and Apps, Connectivity)
• USB Silver Link cable. It connects a USB port on the computer to the the I/O port on the calculator. It requires the TI connectivity software, also available on the TI Web site.
  
• A USB mini A to mini B cable to connect two units.
• An I/O cable to connect two calculators through their I/O ports.

Hello,

Check that the batteries are correctly inserted.
The screen may be too light to see anything.
To darken it

Hello,
Usually, you should not change all batteries at one go.

It is likely that the calculator is ON, but the screen is too light to enable user to see anything. If that is the reason, you can darken the screen.
Press the [2nd] key and release it. Press and hold the UpArrow till screen darkens enough.

You can reistall the system (if needed) by connecting it to a working TI83Plus calculator. You need the calc-to-calc cable.

If that does not work, here is what the Texas Instruments Knowledge Base says about the calculator not turning on.
