Vertical lines in staircase at the start

Hello

Recently, my Early 2011 MacBook Pro 15 "showed vertical lines which were zig-zags in shape. Color was a little tinted air (barely) and the black vertical splitter bar, you see when you scan with four fingers between the offices appeared intermittently. Finally after 5 minutes it would go back to normal. This time that happened 2 or 3 times in a week, then didn't happen again for a few weeks. When she reappeared then, he remained longer and eventually repeated once again.

Now, last time I checked, after having a Service authorised Apple centre run diagnostics (file system and hard drive checked OK, they said that "this problem is known to this particular age model") he was sitting on the bar of the progression for 2 hours Apple logo screen to halfway through the zig - zag lines before I turned off for good.

The thing that bothers me is service technology said it is common for this computer at this age. What the likelihood is that he knows that for sure because all Early 2011 MacBook Pro's today are the same age and I can't imagine having experienced them this often enough to use as their diagnosis.

Does anyone have experience or thoughts on this subject?

I don't think it's common as tech service says, your MacBook Pro is somewhere something wrong.

  • Satellite P100-115 - vertical lines to appear on the screen

    Hello.

    My Satellite P100-115 is 2.5 years but yesterday a thin vertical line appeared on the screen.
    I already checked this problem by connecting an external monitor.

    The line does not appear on the external display.
    Could you tell me what might get hurt? I always took care of the laptop so he couldn't be a race of misuse.

    Hello, Lukas

    You did the right thing and tested it with the external monitor. There is evidence that the display is faulty and must be replaced. It has nothing with the help of the ADB. Such a thing just happens.

    Sorry, buddy, but there are two solutions, either Exchange the screen or use it with external monitor. :(

  • break a subform that contains vertical lines between pages / break the vertical lines between pages

    Hello

    I have a table whose fields can develop. There is an another subform on the side that contains two vertical lines with the height increases if the height of the table increases. The table and the subform are in a provision passed. The challenge is that the subform with the lines does not break between pages. The subform is enabled to allow page breaks, but still it does not break. How to get there?

    I solved by creating the columns on the side and leave the table and breaking lines between pages. The cell border will serve as lines.

  • MacBook Pro won't restart and has vertical lines that go down the scree.

    Recently, my macbook pro to update so I rebooted. To do this, the computer turns on and starts the update but there are lines running down the screen. To about 1/4 of the way through, the screen turns gray, and then shuts down and restarts the process again. I ran a test of equipment and he came without any problem. Is there a way to fix this without going through Apple.

    OK, maybe complicated I don't know.

    Occasional at startup, my screen will be covered in white or green lines and will prevent windows to start so I have to manually turn my pc and turn it on again.

    At first, it was just a problem visually but now its my PC randomly crash. The dotted green line will suddenly appear all over screen of, freeze my PC and I have to restart again.

    It's random, it is not the case whenever I turn on the PC but when it does it is a pain.

    Hello, daz18

    This seems to be either a driver, or more likely a hardware problem. Errors that distort the screen you describe is extremely rare with only software.

    Check with the manufacturer and make sure that you have the latest video drivers for your computer.

    Try to run the memory diagnostics tool: click Start, type memory in the search box and open the Diagnostic tool memory and choose whether you want to restart now or later. After the restart of the tool must be running and then windows starts to tell whether or not it finds problems.

  • Re: Satellite L300 - vertical lines of color on the screen

    Hello
    All of a sudden my Satellite L300 has many colored lines running up and down the screen.
    have never seen this before on any pc, so do not know what could be the cause.

    have tried a search on this forum but found nothing relevant.

    need to know if its worth trying to fix...

    Failed to contact Toshiba other than the robot which is useless.

    Thank you

    I can't say for sure, but it might be faulty display.
    What you can try is to connect the external monitor or TV to the laptop and check if there is a problem on an external device. In case contrary it comes to the display and it should be replaced.

    Googling around you can check how much you must pay for the display again and do a rough estimate, if Exchange is the right option or not.

  • By the numbers, certain cells show an internal vertical line that divides sometimes an entry. How can I eliminate this divide?

  • Blue vertical line on the screen of the Qosmio G20

    A few minutes ago, I was surfing the web and from nowhere share an apperead to the blue vertical line on the screen.
    A blue vertical line near the middle of the screen and crosses the screen all the up toward the bottom.

    If I'm looking at a white background, the line is undetectable, but if it is colored, it comes right thru.

    Please don't tell me they are dead... hoooo pixels... I am now, life away from any toshiba repair shop and I get a guarantee...
    I think that I bought 3 years ago. Need urgent help

    Hey Susana

    I wouldn't say it s a lack of dead pixel, but to me, it looks like a more serious problem.
    It looks like a malfunction of the graphics card. But to be sure, you should try to connect the external monitor to the computer and check if the same vertical line will appear on the second screen.

    If you're going to see the same line on the external monitor, then I assume that the question of the vertical blue line might be linked to the GPU fault.
    This could be the case value because the chip graphic card cannot be replaced. You need to replace the whole motherboard :(

    So, as you see it s not easy to solve this problem and I really recommend to contact a technician who has more experience with these laptop problems.

    Good luck

  • HP Officejet 4632 All in One – scanning with a vertical line through the document.

    Just bought the machine less than a month ago.  Faxes and prints fine and until last week was the sweep for our laptops beautifully... but now is scanning with a dark vertical line up and down the sheet about 1/3 in the document.  What is the cause and how can I "fix" it?

    Any suggestions?

    Thank you

    Hi Rohi63.

    I understand that you have a 4632 Officejet which becomes a vertical line what it is scanned. I'm sorry to hear that, but I'll do my best to help you.

    This seems not only to be the case when using the automatic document feeder, or the glass flat?

    Usually something like this is caused because there is something on the glass. If it only happens when you use the scanner, please get a lint cloth and some glass cleaner (Windex or water if nothing else is available) and wipe the entire surface of the glass for scanning. If this only happens when scanning via the charger, you will see there is a separate strip of glass on the left looking at the scan glass, and you can focus your cleaning there.

    If this does not resolve the issue please try the steps in cleaning several times, but if nothing seems to evolve, please make sure that the printer is connected directly to a wall outlet so that we know, that he has all the power it needs.

    Hope this helps, have a nice day!
