SOURCE: hp pavilion ze5500 display monitor still doesn't work

IT could be a motherboard problem with the function key that controls the switching of the video infomation between the LCD screen and the external video connector.
It could be the function key circuitry on the motherboard that controls the back lighting levels on the LCD.

SOURCE: Dell Latitude D620 no display on main screen!!

Had a similar problem, some video "jitter" and then the screen washes out with backlight showing. ONLY HAPPENS when under battery power.

Cause: a recent reinstall of XP SP3 realized a newer video driver, intel integrated 945gm, than was on the Dell support site. This newer driver is problematic.

Download and install the Dell support site's OLDER video driver for the D620. A new battery won't help, only the older driver.

This is actually a common problem with Dell machines. It is using the external display port as the primary display. You need to go into the display properties and enable the LCD, and then make it the primary. Afterwards, you should disable the external in windows, and on next boot, disable it in the bios if possible.
I used to have this problem come up randomly, whether I was using the port or not. The real trouble is that it will not default back to the internal display when no external display is present.
If you need an option to fix it without a display, you can keep a monitor cable in your laptop bag. If you boot the machine with the cable plugged in, it will not be able to identify your external monitor, and revert to the internal display.

The display keeps going off on my asus laptop about every 2 minutes or less, even when all my settings are set for never go off.


To isolate your laptop problem, first thing you should do is use an external monitor to check if the video chip is OK. You need to press Fn + F4 or F5, F6 depends on your laptop model to activate the display on your external monitor. If your laptop works fine with the external monitor, then your laptop LCD or the inverter(small board that controls the voltage that is sent to the LCDs backlight) went bad.
Inverters is the problem that is easy to fix, you just have to get the correct inverter for your laptop model and your problem is fixed. One way to test inverter is to check it with voltage meter if it is giving the correct voltage.
To check your LCD, use a flashlight. Shine it to your LCD, if you see a faint image then in most cases it is the backlight that needs to be replaced. If you don't see an image even when shining the flashlight then it is most likely the inverter and it should be an easy fix.

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

Meron power pero ayaw mag on


Hi arcymiguel,

If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left from the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor. You may need to press the Fn + F4 or F5, depends on the key designed on the keyboard to toggle between displays.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the issue not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

No display


If the computer is working, then you need to check the display with an external monitor.
If it works, then your display has probably gone bad. Either the LCD itself or the flourescent backlight.

I have no display in ASUS Eee PC 1000H PC Notebook but power and light is there


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Screen Half darker


It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.

There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.

Lcd screen black on laptop. External monitor works.


Defective CCFL backlight may has 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.
  • 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.

The LCD backlight is most likely faulty. If you look at the LCD screen to one side you could see a slight video image, provided the video card is working. To check if the video card is working connect the laptop's video output connector to an external monitor and then boot up your laptop. If you get an image on the monitor, then the problem is with the laptop's LCD display.
As I stated it could be the backlight or a faulty invertot that powers the backlight or it could be the cable/s that connects the LCD to the motherboard.
Try reseating these cables (requires dismantling the laptop).
If this doesn't work then you have a faulty LCD and needs to be replaced. Alternately if cost is too expensive, just use the laptop with an external monitor.
