Have you tried the standard reset prodcedure? Remove one AAA battery from the calculator and then press and hold down the CLEAR key while re-installing the battery. While continuing to hold down the CLEAR key, press and hold down the ON key. When the home screen is displayed, release the keys. If unsuccessful, remove all batteries, including the lithium watch battery, and leave the calculator overnight. I got this from a website. Seems many have had the same problem. http://www.dslreports.com/forum/remark,9246109~mode=flat~start=0 -------------------------------------------------Here is another one:-------------------------------I found this when I was looking for the CONTACT US link to write them.. "What troubleshooting can I try if the TI graphing handheld will not turn on? For the TI-80, TI-81, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-85, and TI-86: 1. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust the lighten the display, use the down arrow. 2. Try a new set of batteries (including the backup battery). 3. Remove one of the AAA batteries, hold down on the DEL key while reinserting the AAA battery. The handheld might display Waiting...Please install calculator software now. Ignore this message. Remove and reinstall one of the AAA batteries again. This time do not hold down the DEL key. 4. Remove one of the AAA batteries, press and hold the [on] key for 10 seconds, release, replace the battery, then turn the unit on. Adjust the contrast. 5. Remove all of the batteries including the round lithium battery for three hours. After the three hour period, reinsert all of the batteries and turn the handheld on. Adjust the contrast if necessary. Note: Step 3 and 4 will cause the handheld to reset and lose its memory." #3 worked for me. I don't know if that's a permanent fix, but it sure turns on normally now. It might change again, if it does, I'll try #4. --
