It can be that the T-Con board on the LCD is bad (blown fuse due to shorted circuits) or it is not getting the 5vdc or 12vdc from the Logic board, you need to check the voltages and caps.

I turned my PC off and it never came back on, screen is black, any ideas?


Check all connections. Unplug them and plug them back in to make sure they are making connection. Some screens will have two cords plus plug it into electric outlet.

If your computer is running look for a switch on the monitor to turn it on.

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.
http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/
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.

Monitor shuts down after 8 seconds


brian967, Well we know what happened after 8 seconds! Now tell me all about seconds 1, 2, 3, 4....7???? You could also tell me if the LCD panel is BLACK or BLACK and BLANK??? How old is the unit? Do you own a soldering pencil 25-40watt? Haven't you visited YOUTUBE to see video clips of "LCD monitor disassembly"/"LCD monitor repair" ??? How is your PC doing? Is it working perfectly when connected to a KNOWN GOOD monitor??? Will your LCD monitor (unknown model#) do same thing when connected to KNOWN GOOD pc? Do you know and understand the BLACK SCREEN flashlight test to evaluate "switch-mode-power-supply" status?? Do you have a digital camera for taking 2 to 3 inch "close-ups" of parts on circuit boards? Does this unit have a "lay on floor" black brick switch-mode-supply, or does unit plug directly into the power-strip or wall outlet(internal SMPS)??? Brian, do some reading in my FIXYA profile so that you will understand all of your options for repairing your unit.But more important is that I want you to know the ROOT CAUSE for your need to repair something that should not have failed in the first place. Get back with reply to this response, if you need assistance. Good luck on your repair. 12fixlouie

HP Monitor comes on with bright white screen since changing PC


Try using a different wall outlet to plug in your monitor. Believe it or not this actually may help.
What ever breakers you are talking about to get the monitor going doesn't really have anything to do with the drivers. Monitors are "plug and play" meaning the drivers are installed for you when you plug it in. It"s possible you don't have the connections on securely or maybe one of the pins are bent. Does it say "restore active desktop" anywhere on your screen?
Also possible the power supply isn't strong enough for your lcd.
