Sounds like the ribbon which runs between the screen and base is being nipped or is not making a good connection. This is a common problem. If that is the problem you may find that by adjusting the screen you can actually get the picture to show again which will confirm but obviously it will continue to happen.

Most laptops have a narrow panel above the F keys which snaps off and reveals the ribbon underneath. Check the connection is pushed in tight and also that the ribbon isn't being nipped, reposition to stop this happening. If it's been damaged then obviously you will have to replace it.

No display problem, vga's out to external, then after 2nd reboot, internal display works, but with errors


If you have already replaced the screen...
Common problem when replacing equipment on laptops is that the "cable" goes into a flat housing that requires you to lift a little white "gate" then insert the cable and put the "gate" back down. Problems usually occur when snapping the "gate" back down. Pull the cable back out and be sure to lift the gate insert the cable and then put the "gate" back down. Once done give it a light tug and it should hold very firm and not move at all

My del studio laptop doesn't shut down


You could have a corruption in the script or a process that won't stop. Try holding down on the power button until the screen goes dark and all lights go out. That is a hard shut down without saving settings. After it shuts down (finally) power it back up. Hit the F8 key on your keyboard the moment your machine goes to the black screen before it can load windows. That is the safe mode. Move the highlight up to safe mode or safe mode with networking and allow it to continue to boot up. Then, when it's completed the process and windows displays that it is in safe mode, do a normal restart. That should resolve the issue.

Run the PSA Diagnostics and Obtain the PSA Error Code

To run the PSA diagnostics and obtain the PSA error code, perform the following steps:
Shutdown the computer.

Press and hold the <Fn> key, then press and release the power button.
Release the <Fn> key when the lock lights above the keyboard begin to flash or Diagnostic boot selected is displayed in the upper right corner of the screen.

Release the <Fn> key.
The PSA diagnostics sequence begins.
After approximately 2 minutes the system produces a number of alert tones.
After the alert tones, the system produces either a series of low beeps or error codes.

Note:
PSA diagnostics will prompt for input during some tests. The resulting error message does not necessarily indicate hardware failure.
For example, input is required during the color bar test. Failure to input a response will eventually result in a timeout error: 1000-0333 Graphics test timed out waiting for keyboard response. This does not indicate a graphics failure has occurred.


Note the sequence of beeps or error codes.

Initialize LCD BIST Diagnostics



You can initialize the LCD Built-in Self Test (BIST) in two ways, depending on the revision of Pre-boot System Assessment (PSA) diagnostics:
PSA versions 3019 and greater run LCD BIST immediately after failing the color bar test, via user input of <N> or waiting for it to time out prior to generating the 3-3-3 or 3-3-4 error. PSA version 3019 became available in November 2005 on various Dell laptops. The PSA version is upgraded with the BIOS.

With older versions of PSA diagnostics prior to November 2005, LCD BIST runs after responding with a <Y> after receiving a 3-3-3 or 3-3-4 error code.
To initiate the LCD BIST on PSA versions 3019 and greater:
Boot to the PSA Diagnostics.
Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics. If the screen is visible, one will see the PSA diagnostics draw a series of multi-colored bars across the screen. When completed, a prompt asking if the pattern was seen appears, accompanied by a brief series of tones.
Press <N> or wait approximately 30 seconds to fail the color bar test.
Watch for the LCD BIST color generation and listen for the beeps every 2 seconds that indicate LCD BIST is running.
LCD BIST runs for approximately 20 seconds, then stops. The 3-3-3 or 3-3-4 error code is then displayed when the LCD BIST is complete. If LCD BIST does not initialize, then the system may not have been upgraded to PSA version 3019.
To initiate LCD BIST on systems with PSA versions prior to 3019:
Boot to the PSA Diagnostics.
Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics.
Press <N> or wait approximately 30 seconds to fail the color bar test.
The system emits a 3-3-3 or 3-3-4 PSA error after failing the color bar test. Wait for two iterations of the failure code and then press <Y>.
Note:
On a working LCD, the PSA diagnostics shows the following message:
Error Detected, continue testing? Yes or No or Retry.


Watch for the BIST color generation and listen for the single beeps that indicate LCD BIST is running.
Patterns of flashing color should appear on the screen. With every color change, an audible beep is heard. If the patterns of color do not appear, and the beeps are audible, an LCD failure may be the issue. If the patterns of color appear, a video card or motherboard failure may be the issue.
IF AN ERROR IS INDICATED, PLEASE CALL DELL SO YOU CAN SEND SYSTEM TO SERVICE DEPOT FOR REPAIR (WE'VE JUST TRIED TO ISOLATE ISSUE TO SEE IF ERROR IS CAUSED BY HARDWARE OR SOFTWARE, OR JUST SOME CONFIGURATIONS)

Thanks and Goood luck! =)

Monitor goes in and out


Hi,
do you mean to say that your system shuts down when you are not pressing the laptop ie, the power light also goes off when you are not applying the pressure, or just the monitor goes blank and power light is on when there is no pressure
in both the above cases i think you should call technical support for your laptop, because it seems like a hard ware problem

Further Queries are welcome

Laptop Display flashs then screen locks up


I wouldn't suspect its anything other than your lcd or inverter. Connecting it to an external monitor cements it. If it was the video card or motherboard it would have certainly done it again. For it to appear locked up would just mean the picture you are watching was the last in its memory to post. Meaning, if the inverter or lcd start having problems, the last thing it was told to display would appear to be frozen to whoever is watching but in actuality its the display not machine that is frozen. Try ejecting the cd tray. Better yet set your power button shut down when pushed. Then have it have another lock up watching a video then push the power button or eject to see if it responds. Then you will know forsure. Hope that helps.
