Did you try [left][right][2nd][on]? It reinitializes the memory and clears the ram.

Backlight spoilt for dsc t90


When the display is to dark or to light, the manual says:
Adjust the brightness of the backlight (page 18).
On page 18 it says:
This sets the brightness of the LCD screen. When viewing images in bright outside light if [Brightness] is set to [Normal], reset to [Bright]. However, the battery power may decrease faster under such condition.
You also can press the button with the > logo, to change between view pictures and record.

The light wont come on!


Use the stylus to lightly press and hold the RESET button on
the left side of your device. The device restarts and displays the
Today screen.

installing/replacing the battery and SIM card.

To perform a hard reset

1. Press and hold the Comm Manager button and Voice Command
button on the device. At the same time, use the stylus to lightly
press the RESET button.

Tv wont turn on


does the light stay or blinking and how about the screen display totally black or a white screen. you can see in a dark room if their is a white screen. if totally black screen then with sound the cause is could be bad inverter board or screen back light. if a white screen it was the t-con board not working good.

Press and hold [UpArrow] until screen is dark enough.

Hope it helps.

When i turn on the calculator i get a dark screen and when i try to adjust the con trast it doesnt change


this is what i think you mean, if i diss-understood you (thought you mean something else) im sorry, then i dont know what to do
thats when you set your ti 84+ screen to very dark. this is how to solve it:
go and open mirage OS, and then just press the "-" (minus) button. the screen should get lighter.

My dell inspiron 1520 has dark screen


If you replaced the backlight and you still have the same problem then the next step you should take is to replace the inverter.

That should solve your problem, if it doesn't let us know.

Loading Screen Freeze


  1. Remove the keypad (for TI-Nspire) or the battery door (forTI-Nspire CAS) and remove at least 1 battery from each column ofbatteries. After 2-5 seconds, reinsert the batteries and turn the uniton. This will cause the unit to reboot the operating system.
  2. Holddown [Home] [Enter] [P], and while holding these keys, press [On]. Thedevice will boot up as in the previous reset, but will display a menuwith the following options. Please try options 2, 3, and 4 in thatorder.

    1. Cancel - The most non-intrusive reset option; no changes are made, the unit restarts. 2. Delete Operating System – The operating system will be deleted without deleting any documents. 3. Delete Document Folder Contents – This will delete the user’s documents, but will not delete the OS. 4. Complete Format – This will delete the OS and all documents for a total erase of memory.
    Note: TI-Nspire family model options 2 and 4 above require that the OS be reinstalled. The reset menu will only display if the unit is off and batteries have been removed/replaced as described above.
