Question about PC Desktops

1 Answer

I turned on my laptop after an hour i turned it off, and it started up ok, just without any picture. The screen is blank, but if I tilt it to the light, I can see everything, but just barely. it's like the brightness has been turned way down, but I've never touched it. I was told it might be the back light that has blown. i've had this similar problem before, but found that it was only because I plugged it into an external screen. but this is no the case.

Have you tried tilting the LCD and see if the symptom change?
If tilting the LCD shows good video, then you have a loose or bad LCD cable going to the System board.
If tilting the LCD does not change the symptoms,then it is the "Inverter" board.
The laptop have an "Inverter" board that goes out and causes this problem. It is located just below the screen on most laptops. I usually purchase them from here:

    I know it's been years, But I totally forgot about this website. Just so you know. The laptop is in full working order. after 3 years of not having a screen, replacing the back light unit, screen ( which was returned) and everything else, I gave up on it and just attached a screen to it. Then 3 years later I decided to upgrade the operating system from Vista to Win7.... and 'as the light shone brightly and the Advent logo staring back at me, I knew I could finally see!' Stupid Window's Vista!!!!!!!!!!!!!!!!!!!!

Blank screen


Try plugging the laptop into an external monitor to make sure the laptop is booting up properly. If it is unplug the monitor from the laptop; or if you know the laptop boots up fine and you get the windows audio when it boots and the initial starting beeps then forget the monitor. Shine a torch or light source on the screen and if you see a faint picture then the inverter on the screen has developed a fault.

My srceen goes Blank


Hi,

first try booting the laptop and pressing the Fn key with the numerical ( numbered key ) that has a picture of 2 screens on it. This is for booting to an external monitor. you could also try adding an external ( pc monitor ) this will eliminate any motherboard Faults.

Secondly, the graphics chip driver may be corrupt or not installed correctly. if you have a restore cd, you could try booting the laptop, with the cd in the drive.

you can then try, to see if the settings in the bios are all correct, by booting/starting the laptop and pressing esc or F2 or delete immediately as the laptop starts. ** Be-Careful** what you adjust.
My suggestion is to look for. ** default settings tab** or load setup defaults.

these are the obvious things to try, before assuming that you have a faulty graphics chip or motherboard fault.

Screen turns blank all of sudden and works normal after switching of the system for 1 hr or so.


You could have a defective screen - a defective inverter or a CCFL lamp.
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.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

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

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

Laptop screen is totally blank as a duster with magnet was used to wipe the screen by erros


It is highly unlikely that using the magnetic duster could damage a LCD screen except putting scratches on the surface of the screen. There is nothing in a LCD screen that can be affected by a magnet. A magnet will affect a CRT monitor because a magnetic field will affect/deflect the electronic beams that hit the color phoaphorus dots on the screen.

Dell flat panel monitor -power button blinks green to amber - no


One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.

what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.

My laptop turns on but then I get a blank screen.


Put in your windows vista CD and boot the PC. It will boot from the CD and you should be able to select a recovery/repair option. Otherwise I believe you can reinstall windows without loosing your data.

You really should backup your data and do a clean install of Vista.

hello chunk
Are you sure that your laptop is not in sleep mode .
Try turning off it by pressing your power button for a couple of minutes and then turn on .
Also charge your battery for at least one hour before operating it upon.
