I have a DV9700 with the very dim image display problem, but works with external monitor. The laptop display will blink on for about 1 second then go dark when closing and opening the unit. From what i have read here, it sounds like an inverter or CCLF lamp. If this is the case, and I don't feel comfortable making the repair my self, who are some reputable repair companies to send it to, with out getting hosed? I was considering PC Pitstop out of New York. Any other ones to consider at a reasonable price?

Need both laptop and monitor on at same time.

Hey Roger,
Below is information that should help you with trying to get monitor and notebook screen to work.
First make sure your laptop is equipped to be able to connect a secondary display, there should be a port for connecting a standard monitor cable on the back.
Connect your secondary monitor and reboot the laptop, the system bios should recognize that a second monitor has been added.
Then right click on your desktop and bring up the display properties dialog box.
Select "settings"
Your laptop should be identified as monitor 1 and you should also be able to see the secondary monitor as monitor 2.
Click on the secondary monitor and check the box that says "Extend my Windows desktop onto this monitor".
Set your screen resolution and color quality for the second monitor and click apply.
Directing icons and browser windows over to the other monitor is just a matter of drag and drop.

Thank You,

Laptop, display problem

Hi,
Dear User..Does the Screen have a displayed Image?
If the laptop has no image at all it can be video card or LCD cable or the LCD panel. About the only non-invasive test you can try is to plug an external monitor into the laptop. This will determine if the problem is motherboard/graphics card or lcd cable/lcd screen. If you have an image on the external monitor then its likely to be lcd/cable/lcd screen.
Is the Displayed Image Faint?
A dim screen can be caused by three things;
1/ The LCD inverter which runs the LCD backlighting
2/ The CCFL backlighting fluro tube in the LCD panel
3/ The motherboard supplying signal & voltage to the inverter.

Thanks

Dell XPS 140 monitor is blank, however the secondary monitor attached displays floating Windows XP. How can I transfer the primary monitor across to the secondary monitory to be able to use the compu

this is from the manual for your computer. you need to get it on both monitors simultaneously.

When you start the computer with an external device (such as an external monitor or projector)
attached and turned on, the image may appear on either the computer display or the external
device.
Press <Fn><F8> to switch the video image between the display only, the external device only,
or the display and the external device simultaneously.

Hi,

I suggest try to use an external monitor to see if the machine will display an output through the external display, if you have display to your external monitor, it means the LCD on your machine is not working.

I have a Dell laptop D505. The laptop powers up but the screen display is very dim. I can't see the image on the monitor. I've tried to manually increase the color/brightness button and nothing changes. ...

Sounds like your inverter or your backlight is failing. The inverter is an easy repair, the backlight can be replaced but it involves taking the LCD panel apart, The backlight comes installed on new screens. I can include a service manual below and possibly a generic guide to backlight replacement....

My notebook screen 3000 n100 goes dark after few second

This could be a faulty CCFL lamp.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these 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 the monitor up first then the laptop, 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.

Does the computer boot up?
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.

Hi,

You could be right about the problem being the inverter or the CCLF lamp, it could also be as simple as a loose cable by what you are describing in your post. If it is the CCLF lamp then you would be better off purchasing a new screen as the labour cost can amount to more than a new screen itself. If its the inverter then it could just need soldering to re-float the solder around the coil.

Seeing as you don't feel comfortable making/troubleshooting the problem yourself then I recommend that you click on the link below and give BnyTech Inc a call and see what they can do for you and at what cost. Link below >>>>

Good luck.

Alternatively you could send it in to HP but it could cost you considerably more that a PC repair store but you will get a full guarantee with their repair. You will however have to send the laptop in and could take a few weeks for the laptop to returned to you.

It is just frustrating that the thing will come on for a second consistently when opening and closing the laptop. I get the feeling that the lamp works, just won't stay lit. I'm leaning towards the invertor being the problem. But I am no expert and need to get this thing fixed at a reasonable price.
