Black Horizontal Line Top of Screen

Hi Chewas,

Thank you for reaching to Dell Community Forum.

Please try the following steps to check the LCD screen:

* Shutdown the computer.

* Press and hold the Fn key, then press and release the power button. Release the Fn key when the message "Diagnostic boot selected" is displayed in the upper right corner of the screen.

* Release the Fn key.

* The PSA diagnostic sequence begins.

* The system produces a number of alert tones.

* You will now see a series of horizontal and vertical color bars across the entire screen.

* You will be prompted with a question if you see the color bars. Press N to forcibly invoke the LCD Built-in Self Test

* You will need to respond to the question within 30 seconds.

* Diagnostics of the remaining components within your computer will continue.

Note the sequence of beeps or error codes.

PSA diagnostics will prompt for input during some tests. The resulting error message does not necessarily indicate hardware failure.

For example: User 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.

Can you also check with an external monitor?

Thanks DELL-Akshatha M...

I did what you told me. Zero Errors. It takes me more than an hour to run all test. No Errors.

I can´t connect a monitor, I do not have HDMI cables. I will look for one this weekend.

How can I write you a private message?

The black line is getting bigger, now is 0.039 inches.

Starts 0.39 inches down from the top of the screen and extends almost 10.24 inches to the right.

Thanks for your help.

I have also experienced the extact same problem with a black horizontal line/s on the top section of my screen of my Dell Inspiron 15 (3537) which first appeared on 30 September 2016 (Australian Time) and the Black lines are now increasing in thickness.

Hi Vinnie 2014.

My problem starts Wednesday September 28  with a black spot, then it was a black line that continues to grow. Now is crosses all my screen, from one end to the other.

Do you know whta is happening?

Maybe the display, some kind of problem in the screen?

Thanks, regards.

Hi Chewas,

I have no idea why this is happening but all I know is that the black lines are getting thicker each time I log onto the computer. Also I did not drop my computer or damage the screen so it is a complete puzzle why this happening especially why the black lines as getting thicker. My black lines are not as serious as your problem with a 10.24 inches on the right or your screen. I have connected the computer to an external monitor and the black lines do not appear so I assume it is the Laptop monitor that is faulty and not the video driver. It is a bit disappointing that this has happen after only two years since I purchased the new Laptop.

I now plan to purchase a new screen and install it myself.

Best Regards

Vince

Hi Vince.

Thanks for your comment.

The black horizontal line now goes from one end to the other and it is 0.079 inches. And it is like you said, not only one line but like 3 or 4 together, making it one thick.  

I will try today to connect my laptop to a external monitor and see what happen.

If the lines disappear, I will start doing what you are going to do, purchase new screen.

And it is totally disappointing, I have mine for just one year...

Kind regards.

Hi Robin.

My screen works with a external monitor.

I was remembering that months ago, a kind of flash appeared in the bottom part of my screen.

It was like a light bulb was flashing, on and off, and after the flashings the part where the flash appeared stayed like it was burn, gray color, more dark than the tool bar.

How I know what screen I need to replace, the number, serie? Without open it.
