Weird display problem.....HELPME PLEASE!!!

Having gone over a month without a response, I assume the hard reset did the trick.

Hello,
Try resetting calculator to default configuration.
[2nd][MEM][7:Reset][2:Defaults][2:reset]. Then [CLEAR] screen.
Hope it solves your problem.

This is kinda a weird situation. Because it's usually the other way around. Your ram will clear if your calculator is frozen. So take out all 5 batteries from the back. Even the back up battery. Then reset it again. 2nd then + then 7 then 1 Then 2. Good luck.

I know your problem
Do NOT HOLD the 2nd button instead just press it once and then press the arrows hard. It will work just fine

It means your pc has your system north configuration wrong. My advice:Call a technician

possibly water damage... there might be an indicater of this such as one on a cell phone. behind the battery possibly, a small sticker that changes color when dampened.

as for solutions... warrenty? lol

have tried replacing its batteries!

try to replace the backup batt

It sounds like you need to put in a new set of back-up batteries. They can be found behind where the AA batteries are.

There maybe electrical shorts connecting the two motherboards, logic part and screen display part, or within the screen display part, causing the weird display when the calculator appears otherwise functional. Open the TI 83+ case following the U Of Washington posting on fixing TI 83+ problem on inability to communicate with TI link cable between calculator and computer. I used the plastic tools in an IPod battery replacement set to open the TI 83+ case as plastic tools will cause less damage to the TI case. Under the aluminun foil are the two motherboards, each a work of beauty. Good work TI. Connecting the two motherboards is a adhesive enbedded connectors sheet. Above that adhesive connector sheet was a different adhesive connectors sheet in the screen display part, which in my case, some of connectors were exposed. I wiped that adhesive connector sheet and the weird display disappeared with calculator functioning. I may buy some heat resistant clear adhesive tape to put over the exposed connectors part for insulation if problem occurs again. The above may or may not be helpful.
