SOURCE: black screen of HP notebook, but external monitor work

i 100% agree with you. i found out that my notebook is one of the recall product from HP. I sent it in for service. A week after the repair, the same problem is back again. So I call HP and they said that I have water damage on the board. I am 100% sure the notebook is no where need any liquid at all time. So they tell me if I want, they can fix it for me for $375. I would highly recommend everyone not to buy HP products!!!!!!!!!!!!!!!!!! I always have problem with HP products and I think they have the worst customer service of all. Once again, do not buy HP products!!!!

SOURCE: dv7-1245dx has no display, but external monitor

Michael,

Take a look at the function key combinations which toggle the display from the laptop alone, to the display with the monitor and the laptop, and the external monitor alone.

In those combinations, you should find one particular set which gives the key combinations for laptop alone, laptop and external together, and laptop off with external on. It sounds as if you have toggled the last of those three combinations. I do not use an HP laptop, so I cannot tell you which keys are the display control keys on an HP.

On my laptop, they are F5, F6, and F7. My suggestion is to look at your F Keys, to find which ones control the external output, and go from there until you discover the combinations which will contribute to displaying back to your laptop's screen alone.

Good Luck,
-a.

Lock A and Lock 1 flashes at start up no display then shuts off


Let's go back in the diagnosis

You checked with an external monitor, to see that the graphics chipset was the problem, correct?

When using the Display Assembly from the 6530b on the 6730b, were you able to use the 6530b's Video Cable, to check it out also?

You are FOLLOWING Anti-Static Precautions?

How did the original problem come about?
Makes a difference.

Display just quit one day, or was there damage; such as dropping of the laptop?

Is the motherboard from a reputable dealer, or is it from a major auction house that starts with an E?

Post back in a Comment

Would appreciate all questions answered. I asked each one for a specific reason.

My HP Compaq 6730b screen isn't coming on. All the


Does it seem like the laptop booted up all the way except the screen is black? If so try the steps below:

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Lenovo 3000 n200 0769AMU press power on switch green light on after about 1 sec screen still black no HD light fan running


Welcome to Fixya

Try to drain the electrostatic charge of the motherboard that usually cause this issue. I wrote a tip on how to do the power drain. Try to plug in external monitor on the VGA port and see if you are getting display using external monitor. If you are getting display using external monitor then the problem would be the laptop LCD. If you are getting the same black screen using external monitor then the problem is already the motherboard.

Thank you for using Fixya!

Using notebook display and external monitor: HP Pavilion zd8205us primary display is garbled, secondary display is clear and good, It doesn't matter which display device you set as primary or secondary


try to switch the blue VGA cable that is connected from the laptop to the external monitor. You may also restart your laptop and set aside the external monitor to check if the laptop is still experiencing garbled display... If it still is, then it is a monitor issue and need to address to HP personnel by calling HP hotline. Otherwise your issue will be resolved by simply doing that..

Blank screen,pwr sup appears to ok, fans runs, pwr light on


The issue seems to be due to defective video card on the notebook. Connect and external monitor to the PC and check if it works fine or not. You can follow the steps listed below to connect an external monitor.

1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

If your PC is under warranty, contact HP to get available options to get the notebook repaired under warranty.

Screen displays for 1 minute then turns black


If you have an HP, you probably have a bad display. They are very bad about that very thing. Where the display hinges are, press on the left hinge just above the keyboard. I have a similar HP and mine has the same problem. I was told a shop that it is the inverter for the display. You might see if there is a shop that can look at it for a small fee.
