Solve : Brightness issues after bootup?

1.	Solve : Brightness issues after bootup?
Answer» Hi, not sure if this is correct section, but here GOES. I have a new pc (maybe 2 months old) This morning i booted the pc up. All went fine, then i saw desktop bootup for about 2 seconds before the screen went blank. I rebooted a few times. Each time i see the desktop for a second or so before it goes black. One thing i noticed after a while. The screen doesn`t actually go black, but in-fact, very very Dark. If i focus really hard i can just about make out my desktop in the background. Not enough to read anything, or control my cursor, but i can definatley make out icons, also when i right click my mouse i can see a faint "square" where the option window will have opened from right clicking my mouse. I`m presuming its a graphics issue, but i`m not certain. Any ideas?1) What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)? 2) What happens when you boot to safe mode?

This sounds very much like an LCD monitor backlight issue. You have in fact described the process for checking for this.

Monitor backlights can be replaced, but if the monitor is old and/or small screen size then the cost can exceed the value of the monitor and even approach pr equal the cost of a new one.

You should be aware that the problem may not be the actual lamp but possibly associated electronic circuitry, and without proper test equipment and expertise you could easily BUY the wrong things and waste money that could be put towards a new monitor or a working used one.

This morning i booted the pc up. All went fine, then i saw desktop bootup for about 2 seconds before the screen went blank. I rebooted a few times. Each time i see the desktop for a second or so before it goes black.
