Screen drakens after I clik and allow a program to run, why?


The screen darkening feature is a common setting in windows when a program is asking to change (install) on your hard drive.
If you are responding yes, but the installation is not occurring or is stalling, you may:
1) need to wait longer (especially if your PC is underpowered as compared to the demands of the new program you are installing),
2) need to check the setting on your security/malware program to assure that it is not in conflict with (and blocking) the installation, or
3) learn that the program you are attemping to instal may require a) a different version of your operating system, or b) more resources than your computer has available, in which case additional memory, hard-drive space or processing power may be required.

LOOKING FOR A REPLACEMENT SCREEN


Darken the screen and either move the lid forward or backwards. Laptops have Liquid Crystal Screens and moving the lid backwards or forward will give the screen a different look.

If you need to adjust the brightness of the screen it is controlled by keys on your laptop. Most times to darken the screen you will have to hit the FN, CTRL or ALT key and hold it down while you hit the key that corresponds to the screen darken key. On some computers (even on my laptop) it will be the down arrow key, so i would press FN+the down arrow key. Remember to hold the first key down while you hit the next key. The icon used for most times to denote the brightness or darkness looks like a circular sun or a washer that goes on screws.

My LG monitor blacks out intermittently when warm, I have tried it on another computer so it is a fault with the monitor. It blacks out every few seconds, sometimes it takes longer. It is 2 years old.


after blackout, check the screen as that. look in to the monitor in side angel,
and if you can see darken live image in that and its working. in that condition, your
LCD panel is working and the problem is no light.
in that case you need to repleace or repair the " inverter unit " in that monitor.
that unit makes the high voltage for back light.

after blackout , you cant see any darken image like as that, and or totally power
goes off , that is different problem. for solve that need advance trouble shooting
and can be need advance repair.

The screen is to bright and wont darken enough


It is likely the video card on the actual unit. If it is under warranty they will likely have you ship it back to them for either 1) repair or 2)replacement
