Screen Failure Same Problem here, is the contrast fix the only solution? doesnt seem to work for me

try adjusting your contrast. Sometimes a full blown contrast setting will blacken the screen. If that doesnt help...contact tech support of the company that manufactured the laptop.

The most likely answer is that the screen has partly failed.
Another user said 'The TI-8X series of calculators work great as standalone calculators, ... I've purchased at least 3 TI-8x's over the years and all of them died (screen failure)'

In windows 7 , -
1 Go to the ease of access column in the control panel
2 Then go to the link "Turn on high contrast..."
3 Deselect it if it is selected
If it doesnt work then-
1 press Alt+Ctrl+Del
2 On the lower left corner their would be a button to Ease of Access
3 press it and deselect "Turn on high contrast "

This should work cause i tried it on my own computer

Turn the calculator on. Press and release the 2ND button. Press and hold the up-arrow button to increase the screen contrast. If you go too far, use the 2ND and down-arrow buttons to decrease the contrast.

Hi,
did you try to rotate the contrast button to left/right by your finger. It doesnt respond to pushing it.

Adjust the display contrast by pressing and releasing the 2ND key, then pressing and holding the Up key to increase the contrast or the Down key to decrease the contrast.

If your inverter is good I,de say your backlight is going bad, I just replaced mine in a sony vaio and now it seams to bright.

if adjusting the contrast from the settings doesnt help then, I don't know maybe you should consult your dealer.

If one of these solutions doesnt work you will most likely need to purchase a new calculator.

Batteries:
Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!

I've had the same problem. A temporary fix that I have found is to turn up the contrast all the way (press [2nd] then hold down the up arrow) until the screen becomes mostly black. Then turn the contrast back down (press [2nd] then hold down the down arrow) until it is at a normal level. If you can get rid of all the white lines when you turn up the contrast the screen will be back to normal. Unfortunately this does not permanently fix the problem because I cannot get rid of all the lines and it seems to be getting progressively worse each time it start up the calculator.
