Monitor Went "BLIND"!

The built-in monitor pannel/screen of my notebook went BLACK all of sudden after 2 years of regular use, and I can't see anything...!
Has anyone ever had the same problem? And any idea about how to fix it?

This is the 2nd notebook I'd experienced the same problem - last one was Sony laptop - and I suppose both Toshiba and Sony got their monitor pannel parts from the same manufacture (in China)!!

Re: Monitor Went "BLIND"!

Do you have a problem with the backlight on your laptop? If yes, you are not alone, that’s one of the most common laptop problems. In most cases the screen inverter is the culprit. Here are some LCD screen backlight failure symptoms that could be related to a bad inverter board:
- Laptop boots as usual but after some time the screen blacks out. You still can see an image on the screen but it’s very dim. You might even use a flashlight to see it better. Sometimes the backlight comes back for a while but then goes off again. In some cases you can turn the backlight on if you tap rapidly on the lid close switch.
- The screen always stay black and the backlight never comes on but you still can make out an image on the LCD. It’s dark, but the image is still there.
-In some cases you might hear a buzzing noise coming from the area where the inverter board is located, it’s on the bottom part of the display assembly.
NOTE: if you cannot see an image on the screen, most likely you have a different problem and there is nothing wrong with the screen inverter.

Re: Monitor Went "BLIND"!

Actually, there's 3 major manufacturers of laptops and parts.
Can you connect to an external monitor and boot the unit up. You may have to toggle (F3 or F5 i think) between on board and external a few times. If you get an image on the external, it's probly the lcd inverter (#1), or the backlight (#2), or the cable is not completely connected to the lcd (#3)
Let me know how the external monitor test works and we'll narrow it down from there.
Good luck

Display went from extremely dark to complely black

Hello there.
I understand that your Notebook is not showing the display lights. To isolate the issue please do the following troubleshooting steps.

1) Check the display with external monitor. If the external monitor is showing the display then the problem is with the LCD screen. If the external monitor is not showing the display then the problem is with the display card.

2) If you have any torch light or a cell phone , try focusing the light on the LCD screen after the Notebook is powered on and check whether you are able to see the texts and images on the LCD. If you are able to see the images and texts then it is the problem of the LCD back-lights. The lights which glow at the back of the LCD panel are not working.

If your Notebook is under warranty HP will repair it free of cost.

Contact HP customer chat center for more information regarding the details of the repair and the procedure for sending the Notebook to HP in case of repair.

For contacting HP chat support click on this link or copy and paste it in address bar of a web browser.

Blank (dark) notebook screen after hooking up digital ext monitor

I notice a difference in the setup of the two monitors, have you installed the correct driver for the new screen?

Try F8 on startup to get into safe mode, this should allow you to use the default VGA screen, and to reset the correct monitor drivers.

This will be a problem with either the screen or screen inverter. Screen or inverter replacement is fairly easy, and you should be able to do this yourself. As far as pricing the screen or inverter, try Ebay. With this being an older model, you should be able to get a good deal on a screen and/or inverter on Ebay, and definitely a better deal than at a shop. If you will get back to me on the model, I can probably get you instructions and diagrams for the screen removal/replacement.

Hp pavilion ze4930us notebook pc is dead

Hi danielb59,

Let do troubleshooting together.

First) if possible, connect a external monitor to your laptop. If you get a picture on the external monitor, then this means your pc is ok but the monitor screen on the laptop has gone bad.

Second) if the monitor screen on the laptop has gone bad, most likely the inverter component on the screen went bad (inverter provide back light). The inverter is replaceable but I do not know what they run. If your laptop is still under warranty, then please allow the manufacturer to fix it.

Those are your choices. Hopefully it helps and good luck.

Suddenly a black screen!

If your good with computer or know some one that is, sugggest you to remove the LCD rim, and clean the ribbon filament that is connected to the monitor. Sometimes this filament get's dirty and just need to be clean from a cotton swab.
Another solution is for you to plug in a monitor to the laptop.
