The monitor or lcd screen is probably going bad or the video card inside
the computer is bad. To isolate the problem try connecting an external
monitor to the laptop. Borrow a Monitor from a neighbor, friend,
relative or co-worker and connect it to the laptop. If the Borrowed
monitor displays ok without the blur and lines, then your lcd screen is
bad and the video card inside the computer is good. If the Borrowed
monitor displays the same way as your lcd screen with the blur and
lines, then your video card inside the computer is bad.
Plug in an external monitor and see if the
display shows up on it. It can be any kind of monitor even the old big fat crt
monitors as long as it has a vga cable to connect to your computer's vga
port. If so that proves your video card is ok. The video will show
on most systems when you reboot without you having to do anything. Some systems
will require you to hit the FN (Function key) + F1 thru F12. Hold down
the FN key then hit the correct key for displaying on the monitor (F1 thru
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.
I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.
For best pictures, you need to set your PC video resolution to the native resolution of this monitor, which is 1280x1024 @60Hz. Try that first before opening up the monitor to look for bad components.
Post back, see what usually goes wrong with SAMSUNG monitors: http://s807.photobucket.com/home/budm/allalbums
morinj_04, "Switch-mode-power-supply" going into partial shutdown mode. Read more of my BLACK screen and BLACK and BLANK screen responses in my profile. You will get the hint as to what to do!!!
Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.
Dell support , would recommend you to buy a new monitor because , they donot do any repairs on the LCD monitors., except for exchanging them, if they are in warranty. You can try the following people , they do repairs on dell flat panels http://www.lcdrepair.us/
I turn on the monitor, I hear a 'cracklin' sound Reply: In a CRT Monitor there is a component called EHT which generates High voltage which is connected to the anode of the CRT, If there is any leakage due to moisture can cause this crackiling sound, You need to clean this high tension wire or replace the EHT ( CAUTION : BE AWARE OF HIGH VOLTAGES )
The screen only shows a bright, thin line. Reply: The vertical Drive section of the monitor is faulty.
