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

Screen is blank , but I have sound , If I shine flashlight onto screen I can see images , enough to try and set control settings


The "inverter" has failed, causing the screen to be very dim.
Is it cheaper to take the monitor to a "TV Repair Shop",
or to buy a brand-new monitor?

Tip

Diagnosing a LCD blank screen problem.


Recently a 3 year old VIzio TV I bought started having problems. The set would turn on normally for a few seconds then the picture would go dark with everything else operating normally including sound. Remembering a similar laptop computer problem I diagnosed previously, I immediately suspected a defective TV screen backlight. To verify this in your own TV, get a very bright flashlight and with the TV operating in the failed blank screen mode, shine the flash light into the blank screen from various angles and distance (including touching the screen). If the LCD is still operating, you'll see a dim motion in the flashlight's reflection, thus proving it is indeed a failed backlight.

Audio really does not matter here---in a very dark room shine a flashlight at the screen with set on to see if you see a very dim image on the screen or not.

Whenever i turn my acer on the screen doesnt show up and i know it is on, one time i started to be able to see the screen dimly but the contrast wouldnt turn up! please help


Try shining a flashlight or a lamp on the screen and see if you can faintly see the Windows desktop in the background. If you can then the problem is the backlight. Laptop screens have a light that shines from behind the screen and lets you see the display. If this is a laptop computer it will need to go in for service. If this is a monitor for a desktop computer you can try turning it on and off a few times, or leave it unplugged for a few hours and try it again but failing that it also needs service.

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
