Press and release the "2ND" key. Then press and hold either the up- or down-arrow key. Up-arrow darkens the screen, down-arrow lightens it.

My screen is completely dark


It might be enlightening for me to know under what circumstances this eclipse happened. If that happened after a battery replacement the screen contrast has changed.
To restore the screen to its usable self, you should adjust screen darkness.

  1. Press [2nd] key and release it.
  2. Press and HOLD [DownArrow] to lighten screen.
  3. Release the [DownArrow] when contrast is adequate.

The screen is too dark to read


See if there is a contrast adjustment somewhere on the laptop first, if not then its a possibility your back light has gone and needs replacing.

My calculator works fine but recently when I use it the screen is very light. I already have it on maximum darkness and sometimes it works but occasionally the screen flickers?


Hello,
When screen is at maximum darkness you see almost nothing.

Here how you change screen contrast (just in case another readed does not know how to do it).

To increase contrast:
1. Press [2nd] key then release it
2.Press [UpArrow] key then release it.
3. Repeated steps 1 and 2 in sequence, until contrast is dork to your taste.

To decrease contrast:
Follow the algorithm (a very big word for procedure) above substituting [DownArrow] for [UpArrow].

Hope it helps.

Real dark screen on Toshiba A135-s4437


First I would check to make sure that the contrast/brightness buttons on the laptop weren't accidentally changed, making the screen dark. Also, try with and without the battery and power supply. Otherwise, unless it is actually the screen that is defective, it is usually a power converter replacement, which is a small circuit board, usually under the plastic cover directly under the monitor, which supplies power to the monitor. You may want to take it to a shop as they can isolate the issue easier.....
