If you hear the hard drive spinning and you think Windows is working but you can't see an image then :-
Youcould have a defective screen - a defective inverter or a CCFL lamp orsimply the video cable needs reseating. After reseating the video cableand the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
Allthese symptoms indicate that the LCD backlight lamp (CCFL Lamp) hasreached the end of the life and all you need to do is replacing theCCFL lamp

Connect an external monitor to your laptop andpower it up, if you see the normal Windows images then the video cardand laptop is OK and the problem is definitely the backlight.

Dimimage and/or dark display on the laptop's LCD screen indicates a faultyLCD backlight and it could be the inverter that supplies high voltageto the CCFL lamp or it is the CCLF lamp is nearly burnt out or burntout, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

No display


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Why does my LG flatron 1953T LCD monitor (19') goes white


Because the fuse on scaler PCB is blown. Open the monitor, open metal cover, disconnect all cables coming between display and boards, take the chassis off the display.
On back side of display you will see metal cover, mounted with tiny screws, take them off. Unscrew the board also and carefully tilt it up. Observe tiny chip fuse (referenced F1 or FU1 or something with "F") somewhere nearby the connector, ring it, replace it with solder drop.
Take everything back together.

Lcd monitor asus dont work after half our power on


Your monitor is set to turn off after one half hour, as a power saving measure, and you can reset the timing of this feature on the monitor, or in the power saving section of the display feature in your operating system under "displays"whether in a Mac OS (System Preferences) or in Windows in My Computer.

Reset the length of time you wish your monitor engaged in either or both.
