No vidio display screen show nothing att all. The computer starts but I see nothing.


If you shine a flashlight at the screen and look it from an angle and can see your displayed screen faintly then the inverter board is bad and it needs to be replaced.

You can hook up an external monitor to your laptop in the meantime to use your system.


There is also the posibility your screen is no good. I'm thinking it will be the inverter board though.

Monitor flickers and faint bands scroll down the


could be fixed by ajdusting the refresh rate....

you could try this (xp pro sp2)

please rate if useful, good luck

Open Display in Control Panel.
On the Settings tab, click Advanced.
On the Monitor tab, in the Refresh Frequency list, click a new refresh rate.

To open Display, click Start, click Control Panel, click Appearance and Themes, and then click Display.
  • The default refresh frequency setting is 100 Hertz, although your monitor may support a higher setting. Check your manufacturer's documentation for information regarding the settings your monitor supports.
  • A higher refresh frequency reduces any flicker on your screen, but choosing a setting that is too high for your monitor can make your display unusable and cause damage to your hardware.
  • Changes to the refresh frequency affect all users that log on to the computer.

HP (dv2000) laptop will not boot up at all


It appears to be a video card/mainboard problem very common with the symptoms you have described. Try to connect the laptop to an external monitor (see the associated buttons too). No video signal on the external monitor could indicate a damaged video card/mainboard. Not worth it to be repaired and the replacement is expansive. Check the price on a professional repair store. There are new laptops on the market more powerful than yours for about 500-600$. So you can make a choice. Less common, could be a memory problem.Try the laptop with a good previously checked memory (or if there are 2 bars in your laptop, try them one by one). If you do not get any video signal on the external monitor have the laptop, first diagnostic is most probable.
In both cases, if you get a video signal on the external monitor it means your screen is defective (also expensive to be replaced).

Hp dv9000 will not start up. blue lights are go


you get a black screen right, nothing at all then no bios, no logo, nothing at all?
Do you get any beep codes and if so in what order?
did you try different ram?
First try to plug your laptop to an external monitor. If it works, you screen is bad, if it doesn't you probably need a new motherboard.

No Display


First make sure everything else is getting power and operating okay, and that it is only the LCD display that is non-functional.

If you get no video signal or power at all, even at boot time, you probably have a dislodged ribbon cabling or power connection. Usually when LCD monitors go bad they show colour banding or all white, etc., but usually continue getting power.

As a last resort, try disassembling the lower case (with the power disconnected and the battery out of course) to expose the LCD monitor mounts, and then following the wiring from the screen into the laptop and check for anything loose or disconnected. You could also have a loose ribbon cable going into the LCD array, which will require disassembling the LCD cowling and mounts.

If you are handy and comfortable with electrics and find nothing loose, put the battery in and test the power line going to the LCD backlight, which should be getting above 7V (I think). Below that and you either have a bad video controller or bad wiring/solder joints somewhere. Otherwise, if the unit has been dropped or had a hard life generally, it could also be the connections between the LCD connector bus on the monitor array and the array itself. As a last resort, try unplugging and reconnecting all ribbon and connector cables, cleaning the exposed brass coloured runners lightly with rubbing acohol or even a pencil eraser.

Good luck...
