Question about HP Pavilion dv4000 Notebook

1 Answer

Screen extremely dim

"someone" spilled something on a laptop and now the screen is extremely dim, you have to shine a flashlight on it to see anything. I replaced the inverter, still no fix... then replaced the entire LCD screen, still doesn't work!! There is one more solution I'm trying and that is a flat cable that connects from the mobo to the screen (it didn't come with the new screen, so I used the old one) ... I'm hoping that's the problem.

But while I'm waiting for that to arrive, does anyone have any suggestions?

Thanks :)

I think you should look at the sleep button on pin.When you close LCD it should push that pin down(Stanby or sleep pin).
When you press or it get stuck, this pin will block or not send voltage to inverter so that the light on monitor should go off or computer go to standy or sleep mode.Check this one.
best of luck,takecare

Hi, Do this test for me. Turn laptop on. Get a flashlight and shine in on screen check for start screen. If there is life in. Then you know it is a screen problem. LCD light problem. If you are computer and electronic savy remove and or disasemble screen. If you are not take it to someone who can and repair.

My hp coa-se laptop mdl 661631 fhe screen is so dim u cant see it... how do i fix it?


The image on your screen is made up of two parts the lcd screen that creates the image that you can see dimly and a backlight that shines trough the screen brightening it so you can easily read the screen. In your situation in would appear the backlight bulb is burnt out and needs to be replaced. If your handy this is something you could do yourself a search on google for "backlight" and your specific laptop model will bring up available replacement bulb and quite possible detailed instructions on how to replace

When i switch on my laptop I see the led lights on but the screen is blank. I do not even see the hp icon that shows up initially


Hello !

It is typically the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

Hope this helps.

Will not turn on? Battery is charged and power adapter on. No response at all?


This can be a few things first see if the fans and hard drive are spinning. If neither is it normally means the motherboard has failed and needs to be replaced.

After that if both are on and spinning shine a flashlight on the screen. If you see a dim image of the desktop it means the back light had died and needs to be replaced.

If the image is not dim and both are on try connecting an external monitor to the laptop. If you don't see anything on the external monitor either it means the laptops video card has failed and needs to be replaced. However if you do see an image on the screen it means either the laptops LCD cable or the LCD itself needs to be replaced.

LCD starts to display for about 2 seconds then goes dark.


lamp(s) perhaps.... with an LCD monitor (the desktop kind) you can shine a lite behind it. if you can see things on the screen it's the lamps... if you can't it's something else.

Help Please.


Is it so dim that the screen cannot be read with shining a flashlight into it? if so this is a hardware failure not a brightness setting. let me know if it is.

If it is just somewhat dim but readable, there is probably a hotkey. Gateway laptops are all different.

Google search for your particular model and specifications. you will get the gateway support page for your notebook.

for example if you have an mx6550 enter this at google.com
