Help!!a Black screen appears when I turn on my calculator

Http://oakroadsystems.com/math/ti83oops.htm#Lines

ok guys, after about 10 years of not using my ti-83, i put the new batteries in and got the black screen you are all talking about.. came to this site.. saw no solutions.. kept looking.
I've fixed my calculator, but my brain won't tell me exactly how.. but i followed those instructions..
you CAN see what is on your screen if you tilt it under the light ... just fiddle around until you can see faint writing on your screen under the black.
Press window

i have these entries in my calculator
xmin=-10
xmax=10
xscl=1
ymin=-10
ymax=10
yscl=5
xres=2

then go and press second and the down arrow to lighten your screen. it should work.

With 2nd ▲ or ▼ you can change the colour of youre display from dark till very white.

Go to the 2nd button on your calculator, press it, then release it and press the down arrow to lighten the screen. keep reapeting this until the screen isnt black

Hey guys!!!!

Push the 2nd button.. And then push and hold the up arrow key. If that doesn't work.. Do the same except with the down key.

I had the same problem with a TI-83 once. Each time it was powered on a fully black screen would show. It would NOT power off by pressing the keys. A battery had to be removed to power it down. (The contrast could NOT be adjusted with the 2nd and arrow keys; it would do nothing other than display the black screen.) Try pressing DEL and/or CLEAR as you power it back on. I think I held down both DEL and CLEAR to fix mine. It took me MANY tries to get it to work though. I was about to give up on it, and it began to work, so be patient! NOTE: This may ERASE ALL YOUR PROGRAMS!!! That wasn't an issue for me because I didn't have anything on the calculator. Good luck! :)

I have a TI-84 Silver Plus and the same thing happened to me. I was desperate to fix it because I had math finals the next day. So I pressed the blue '2nd' button, and held down the down arrow and it worked! If that doesn't work, go see if it can be repaired somewhere!

I had this problem once with a TI-83. It would NOT power off after that black screen came up. I had to remove a battery to shut it off.

I held down DEL and/or CLEAR when pressing the on key. That fixed it. I had to try it many times though before it worked. Be patient! I think when it finally worked I had held down both DEL & CLEAR upon pressing the ON key.

NOTE: This procedure MAY ERASE YOUR PROGRAMS. My calculator didn't have any programs, so it wasn't an issue for me.

Good luck! :)
