Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?

Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].

If it's not the angular mode, please reply to this post and give an example or two.

The electronics decay after a while and if left on for a while, may recover but probably won't.

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.

Are the batteries fresh? Try putting new ones in. If that doesn't help then your LCD display is probably damaged and it will probably get worse. Can it be fixed...probably, but what's worth to you? If the calculator is only worth $50 (IDK?) but they want $100 to fix it at an electronics repair shop...is it worth it?

Your calculator may have a defective power switch and it is drawing power even while appearing to be off.

Check to make sure TI-Connect is looking on the right port, whether USB or serial. If you have a serial cable, you might consider using Ti's Graph-Link software to connect. I have had trouble getting it to work right with TI-Connect. You can find Graph-Link on TI's Education site under Downloads > Connectivity Software. I personally prefer the free program TiLP, which runs on Windows, Mac, and Linux and supports whatever cable you want. Hope this helps!
