I think its battery has been dead try to replace the battery.

do you hear any system beep on boot ? if you do , and you still have a blank screen you have a faulty monitor or cables

CHECK IF THE BATTERY IS GOOD IF NOT REPLACE IT

If the battery is good, mine died after 4 years, check the settings in Power Options, look for dim when on battery power. Increase the % to Max or 100%. see what happens. Still have problem consider replacing Battery.

Hello,
Reduce the contrast.
1. Press [2nd] key and release it
2. Press [DownArrow] and release it
3. Repeat steps 1 and 2 in sequence until screen lightens to your taste.
Hope it helps.

If you can find an older SVGA monitor, try hooking it up to the port on the back of your mac. If you get video then chances are the LCD display is shot.

Black-Screen/Black-Pixel Fix for TI-Calculator

This will erase all memory and reset defaults.

1. Remove 1 AAA Battery
2. Press and Hold 'ON' for 30 seconds
3. Replace AAA Battery
4. Adjust Contrast to appropriate level

If this fails, try again with ALL Batteries removed including
the backup Lithium Battery.

If all else fails, try the following reset procedure:

1. Remove ALL Batteries (inc. Backup)
2. Let Calculator sit with no batteries for 2~4 hours.
3. Hold 'ON' for 30 seconds.
4. Replace all the batteries (May be good idea to use new batteries
just in case old ones were dead)
5. Turn on Calculator
6. Change Contrast to appropriate level

- Remember to use correct batteries or calculator may not work. The
correct batteries are Alkaline, Rechargable Batteries are TOO WEAK,
Heavy Duty batteries are TOO STRONG.

My daughter is now going through two replacements for the screen going blank on this model. I'm still having to pay a deductible for a phone that was replaced the first time for the same problem this time. Evidently this is a common problem with this phone.

Replace inverter or possible the back light bulb.Better yet replace the screen.
