Here Im going to post some laptop screen photos showing bad video output. Ill explain what was wrong with the screen and how I fixed it. I plan to ad more examples as soon as I get new pictures. If you have your own example and know how to fix it please let me know and Ill post it too. Example 1. Heres a picture of Satellite M5. LCD screen I made this morning. I got this video output as soon as I started the laptop. There were a lot of vertical lines, and they were changing color without any pattern. To me it looked like Northern Lights never seen in real life. The external monitor worked fine. As soon as I applied some tension to the screen it changed the pattern. Some horizontal lines appeared in the middle of the LCD. Heres the difference. When I torque the screen, the image appears but its distorted with some horizontal lines running across the screen. Reseating the video cable didnt make any change and the problem was fixed after I replaced the LCD screen. Dells new Vostro line of computers developed to meet the needs of small businesses has become very popular among working professionals and consumers alike. The. It was never the official position of the FCC that it was a DDoS attack, Gigi Sohn, former counselor to thenChairman Tom Wheeler, told Gizmodo. Example 2. I took this picture from Toshiba Satellite M6. I think that this example is very typical. One day you wake up, turn on the laptop and see one or a few hair like vertical lines in different colors. When you move the LCD screen some lines might disappear or more lines appear on the screen. A video output on an external screen would be perfect, without any lines. Unfortunately, these lines indicate a screen problem. Ive never seen this kind of video output caused by a bad video cable or bad FL inverter board. My laptop was fixed after I replaced the LCD screen. Example 3. The photo below comes from Toshiba Satellite 5. The laptop displays identical vertical lines all over the LCD screen as soon as I turn it on. Wifi Cracker Tool Version 3 46 Latest Version Rar on this page. Sometimes these lines are red, sometimes they are blue, sometimes they become wider and change color to white. The same pattern appears on the external monitor. It displays same vertical lines. When the same video defect appears on both monitors internal LCD screen and external screen, then most likely it happens because of a bad video card. On some laptops the video card is integrated into the system board, on other models its a separate module. In this example, the vertical lines were caused by a failed video memory on the system board. Ive tested the video memory with Microscope utility and it failed the test. In Toshiba Satellite 5. To fix the problem, Ill have to replace the board. We do not have equipment to replace the memory module itself. Example 4. Heres another example of a bad LCD screen.

Dell Xps M1210 Fan Control Software' title='Dell Xps M1210 Fan Control Software' />My bad It wasnt the LCD screen problem. As soon as I turned on the laptop, I was getting these reddish marks on the LCD screen but not on the external monitor. Reseating and replacing the video cable didnt help. The problem disappeared when I installed my test LCD screen. Yes, for some reason I wasnt able to reproduce the problem on my test LCD screen. But the reddish video appeared again as soon as I replaced the screen. I guess it happened because the system board had some kind of intermittent problem with onboard video or video connector. Long story short, I had to replace the system board and it fixed the problem. Yep, I misdiagnosed this laptop. Example 5. Heres one more example of a faulty LCD screen. The left half of the screen works just fine but the right side is completely white. Example 6. Heres another laptop with a bad LCD screen. This time its a tablet PC. Example 7. This screen looks like the screen on the example 1. I hooked up an external monitor and the external video works perfectly fine. Heres the difference. When I torque the screen, the image appears but its distorted with some horizontal lines running across the screen. After a few seconds the image washes away. I had to replace the LCD screen. Example 8. This laptop displays inverted colors right from the startup. As you see, the Toshiba logo is light green instead of red. The background is light gray instead of black. The Intel logo should be blue on a white background but it is red on a black background. When your laptop displays inverted colors as on the picture above, this is an indication of a bad screen. Youll have to replace the screen. Example 9. Here are two more screens. In both cases this problem is related to the LCD screen, witch means the screen has to be replaced. On the image below you see a white band running from the top of the screen to the bottom. This band appears right from the laptop startup and runs through the logo too. On the following image only the left side of the screen is working properly. This problem is caused by faulty LCD screen.

Failed Sense Pin in Laptops with HD Audio this section does not apply to older laptops with AC9. Section 3Dell laptops with HD audio all models since 2. In addition to the usual mechanical parts, the jack uses current impedance sensing circuitry to trigger software configuration and switching to send the audio signal to the speakers. These techniques are called the sense pin in this article. Sap Gui Codepage Unicode here. When the sense pin fails then there is usually this combination of symptoms    Speakers dont work and are not muted or deselectedHeadphone jack does workReinstalling audio driver does not helpAudio test in Dell 3. Diagnostics passes, or the speakers work in PSA testsOn models with 2 headphone jacks, one may be checked in the control panel as if in useSometimes but not always, a very gentle wiggle of a plug in the jack will get it to resume normal functioning, at least temporarily. That combination of symptoms means that the sense pin is not working for some reason. Failure of the sense pin results in the computer behaving like there is always a plug in the jack. The software switch that should route audio to the speakers does not get triggered. There are 3 ways to confirm that you have a failed sense pin 1. Check for the combination of symptoms that I listed. If you have all of them then it is pretty certain you have the failed sense pin. Note that when you run the audio tests in Dell Diagnostics you should hear audio through the speakers. That is the opposite result from what one would expect. But note that if you do not hear the audio through the speakers during the tests then there is some other hardware problem, not a failed sense pin. Replace the headphone jack. If that fixes the problem that confirms that you had a failed sense pin. Restore the laptop to its original factory configuration by using Factory Image Restore on models with Vista, 7 or 8 pre installed at the factory or PC Restore on models that had XP pre installed. If the speakers still dont work after restoration and you have the combination of symptoms listed above, that is a definite confirmation of a failed sense pin. Headphone jacks are not designed to be repairable so normallya jack with a failed sense pin has to be replaced. Changing the jack on most models requires replacing the motherboard, but some models have a separate jack circuit board that can be replaced with a new one. See Section l. V below for a list of models with replaceable jack boards. See Section V for some workarounds that will help on a few models. Sometimes gentle prodding or application of pressure on the jack case can restore functioning. On some models a salvaged jack can be soldered onto the motherboard depends on the design of the MB and ones ability to work on it. But if you are still under warranty then let Dell fix it or you risk voiding the warranty. How to Use Diagnostic Tests to Help Confirm a Failed Sense Pin. A. The PSA or e. PSA tests. All Dell laptops have this ROM based diagnostic tool. Use it to rule out speaker failure. Re start the computer and at the Dell logo screen tap the F1. Poser 6 Free Download Mac. One Time Boot menu appears if the computer boots to Windows turn the computer off and try again. At the One Time Boot menu, press the down arrow key to highlight Diagnostics, then Enter. Look for a Perform Quick Audio Check button on the bottom right side of the e. PSA main menu screen. Press the button and check if you can hear the beep tones from the speakers. If you do not have the Perform Quick Audio Check button then do this. Start the PSA tests and when it performs the color test it will ask you if you see the color bars on the screen. Deliberately fail the test by answering no press the n key instead of yes. When you do that the PSA test will emit a series of beeps. Listen for the beeps. If you dont hear the beep tones that means that the speakers have become disconnected or have failed. You do not have sense pin failure. If you do hear the tones that means that the speakers are working and are connected. If you also have the other symptoms listed above, you almost certainly have sense pin failure. B. Dell 3. 2 bit Diagnostics Tests. Most of the older models also had a set of interactive tests named Dell 3. Diagnostics. If you have these tests they will run after the PSA tests finish. Dell 3. 2 bit Diagnostics tests the audio chip, not just the speakers like the PSA tests do. However if you have the other symptoms listed above, your audio is working through the headphone jack and the audio chip is okay. In other words you do not need to run the Dell 3. Diagnostics, just the PSA tests to rule out speaker failure. Here are instructions for the Dell 3. Diagnostics. 1. Run the PSA tests see above. Dell 3. 2 bit Diagnostics should open after the PSA tests, or you should see an option to open it. If you have ever reformatted your entire hard drive then Dell 3. Diagnostics will no longer be there as an option. In that case run it from the Drivers and Utilities Resource CD that was shipped with older Dell laptops. Select Custom, then the audio tests. If you do not see audio tests under Custom, that is a symptom of a failed audio chip however if your audio chip has failed then you would not have any audio at all neither through the speakers or headphone jack. The tests will run. You dont need to run all of them. Just check whether or not audio comes through the speakers during the tests. The Dell 3. 2 bit Diagnostics audio tests play a complete piece of music, not just beeps and tones like the PSA tests do. If you dont hear the music that means that the speakers have become disconnected or have failed. You do not have sense pin failure. If you do hear the music that means that the speakers are working and are connected. If you also have the other symptoms listed above, you almost certainly have sense pin failure. Headphone Jack Problems on Older Models with AC9. Audiothe 2. 00. 5 Inspiron 9. Dell laptops built before thenThese old models did not have a sense pin in the jack and so do not have the failed sense pin issue, but there could be other problems with the headphone jack. There is a mechanical switch between the headphone jack and the speakers but no software, so if the audio signal gets as far as the jack but not on to the speakers it is a hardware problem either in the switch or in the wiring to the speakers. When you insert the plug into the jack the plug pushes apart the spring contacts and breaks the connection to the speakers. When you pull out the plug the contacts should spring back together. If this fails to happen due to a misaligned contact for example, you wont hear sound from the internal speakers. Sometime gently probing the jack with a q tip can restore functionality. If the speakers work when you apply pressure to the case then the problem could be a bad solder joint where the jack is attached to the motherboard instead of a bad spring contact.
