Re: non working of lcd
Hi this is the way how to examine what's wrong with your LCD
monitors. Power on both CPU and monitor. After it went blank, you have to
check if you can see the image on the screen or not by shining a flashlight into the
screen, not directly but find the best angle to the screen and take a look very
closely. If you can see the icons or any image, there will be a minor problem.
Like me, I can see window image using flashlight and check lamps inside. Some
of them were broken and it is easily replaced. If you cannot see anything on
the screen, there'll be some problems with inverter board. If you have
soldering tool and want to fix it by yourself, check the caps first. It may
cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.

It might be the connection loose of power cord problem or check your TFT power connector inside the TFT if you can open the TFT screen!!! It may be dry solder…. Other wise go to repairer and do the same….!!!
The LCD monitor is actually a active matrix of small transistors (3 for each pixel). They have one native resolution, a FIXED one for example you monitor has 1024 x 768 pixels. This results in 786432 pixels displayed on the screen. Because each pixel is controlled by 3 transistors there will be 2359296 transistors controlling your entire screen. This is a fix number. You can't raise the resolution to 1280 x 1024 because this will require as you can see now... a lot more transistors on the same surface.
All you can do is to lower the resolution, in this case 4 pixels (12 transistors) form a larger pixel acording to that lower resolution. The image can look blurry in these situations.
THe bottom ideea is that a LCD pannel (more corectly said, TFT (thin transistor film) pannel, has one optimum resolution, it's native one. The higher the better, when choosing one to buy, but you can't raise the resolution over that. You can just lower it.
It works different then the normal conventional CRT monitors.
Sorry for my bad english as I live in a non english-speaking country. Also if you have anymore questions please post a comment.
