White screen on hp w2007 LCD monitor.

Troubleshoot an HP LCD Monitor
HP makes a number of liquid crystal display, or LCD, monitors.
LCD monitors create an image by passing light through a liquid crystal solution that either blocks the light or allows it to pass through to a color filter.
LCD monitors are ideal for use with a computer as they present an excellent still image and cannot suffer pixel burn-in like other flat-screen display technologies.
Even quality monitors run into the occasional problem and need some basic troubleshooting before sending them in for service.
Check the power cord to make sure that it is plugged in securely to both the monitor and the outlet. If you are using a surge protector, remove it and plug the power cord directly into an outlet that you know is working.
Detach and reattach both ends of the cable running from your computer to your monitor.
If your HP LCD monitor has more than one connector, use the other one to make sure that the connector isn't the issue.
Remove any switch or extension cable that may be present between the computer and the monitor.

Restart your computer. A fresh start will correct many software issues.

Check the documentation of your video card to make sure that it supports HDCP, or High Bandwidth Digital Content Protection, since the screen may be blank when you are trying to watch high-definition content through a video card that doesn't support it.
Some older HP LCD monitors also do not support HDCP, so check your monitor documentation as well.

Go to your video card manufacturer's website and install the latest drivers for your video card. Instructions for installing the drivers will vary by manufacturer, but they should be listed with the driver software.

Change your resolution to a preset video mode to make sure that you aren't trying to operate the monitor in an unsupported resolution.
Different models of HP LCD monitors support different preset video modes.
All of the preset video modes for your monitor are listed in your monitor's manual.
Resolutions of 1024 x 768 and lower are supported by almost all HP LCD monitors.

Press the "Auto/Select" button on the front of the HP LCD monitor to correct any images that are dark or blurry.
If this does not correct the image, press the "Menu" button on the front of the monitor to bring up the on-screen display menu, where you can use the "+" and "-" buttons to scroll through the options and "Enter" to select the option that you want to change.
Adjust the brightness and contrast as needed by selecting them and using the "+" and "-" keys. Press the "Menu" button to exit the menu.

Press the "Menu" button to enter the menu, scroll to "Image Control" and press "Enter."
From here you can choose the "Auto-Adjustment" option and the HP LCD monitor will automatically adjust the horizontal and vertical positioning to center the screen.
The ability to adjust these settings is available only if you are using VGA inputs.

Contact your retailer or manufacturer for any additional troubleshooting steps for your particular model of HP LCD monitor.
If your monitor still has issues, you may need to send it in to be serviced.

Fix a White Screen on an LCD Monitor
When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty.

You will need to troubleshoot these possibilities to determine which problem you have.
If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it.
Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot.
If your computer display does not show on the functioning LCD screen, try rebooting your computer.
If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance.
If your computer display shows normally on the working LCD screen, proceed to Step 2.
Unplug the LCD monitor with the white screen.
Disassemble the rear panel of the monitor with the small screwdriver.
Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor.

Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen.
See the References section for photos of the video cable for assistance.
Unplug the cable, checking for any debris or blockage.
Reconnect the cable firmly.
Reassemble the LCD screen. Plug it in and connect it to your computer.
If the screen is still white, you have a defective LCD screen.
You will need to replace it or take it to a professional repair service for assistance.

Without this test you'll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.
You'll have to disconnect the video cable from the LCD screen (connector 2) and the inverter board (connectors 3 and 1).
After that you connect another working screen and test video.
For this purpose I'm using one of my test LCD screens.
My test screen is cracked and because of that you see a wide white band in the center but it still works fine for this test.
The original screen is white but my test screen works normal (except the crack of course) and I can see the image.

After this test I can tell that the problem must be related to the screen.
After I assembled everything back together and connected the original LCD, it's still white.
CONCLUSION. In my case this problem is related to the LCD screen and it has to be replaced.

Our HP 21 Digital projector has a green tint when we turn it on. We have a new computer and the monitor displays correctly. The HP21 is a 2004 model.

Hi it sounds like you have a ne missing on the VGA feed to your projector, try using a composite lead to see if it is the same it should be ok also you can try using the menu see if the white is white when menu is pressed if it is then it is the lead, it possible could be the VGA socket but i have never seen a faulty socket so unlikely.

Display problem


Sounds like your Mainboard will need repair or replacement if you only get a white screen.

Check if the unit is still under warranty as this could be a costly exercise.

Hi Ronnel

This is a common Mainboard failure on a Projector.

The unfortunate thing is that the Mainboard will either have to be repaired or replaced.

PB6100:No picture display

The projector needs to be turned on first, then connect it to the laptop. If the picture still does not show at that point, press the FN and the LCD keys on your laptop at the same time. This should work.
