Flickering horizontal lines always on screen (XPS 15 9530)

My system:

DELL XPS 15 Laptop 9530

Windows 8.1

About three weeks after I purchased this machine, flickering horizontal lines began appearing across the screen.  They are transparent, a little less than 1cm in height and traverse the whole width of the screen.  Each line is separated from the next by about a quarter of the screen height.  There are three of them currently and they always appear at the same height on the screen.  They are barely noticeable on a white background but can be prominent and annoying on dark backgrounds or photos etc. 

Have run all the diagnostic protocols on the DELL website – everything working perfectly. 

Not sure whether this is a hardware or software problem.

Any help appreciated.

Hi ,

Thank you for writing to the Dell Community Forum .

In this case do confirm if you have performed these steps and advise ,

*Have you checked the system's performance in safe mode ,because safe mode uses very minimal drivers and graphics if the issue is seen in safe mode then its a hardware issue.

*What happens when an external monitor is connected to the system ?If the lines are not seen on the external screen then the system board works fine  .

*Have you tried to initiate LCD BIST ( by restarting the system and pressing the D-Key on startup ,solid colours should be visible clearly if the test passes )

*May I know how were the diagnostics initiated on the system.

Hoping to hear from you soon with the service tag of the system (send it via private message only ) so that I can check the specifications of the system .

Kindest Regards ,

Hey, 

Sorry to barge into this thread, but I have the EXACT same thing. Did you ever find a way to rectify the situation? My XPS is about 3 months old and for no apparent reason this two lines appeared.....

I have tried the safe mode but as that is a white screen it's hard to seen the lines anyway.

Th D button colour screen start up seems ok.

Struggling to find another cause.

Thanks

James

Good day James ,

When the system reports distorted video the video drivers or the LCD panel or the system board could be faulty .

*Connect the external monitor to check the display,if the display is distorted on external screen then its a system board failure issue .

*We also ask the customers to perform LCD BIST ( Built in self test ) by restarting the system and tapping the D-key ,now that you have performed that test if the colours are visible clearly then the LCD panel works fine .

I hope this information was helpful but if there are any queries do reply to this post with the service tag of the system so that I can assist you better .

Kindest Regards ,

Hi again:

I have now run the LCD BIST, the colors seem to appear fine.

The external monitor also appears to be fine.

As I have said before I have run in Safe mode, but it is difficult to see the issue as it doesn't show so well on a white background

I have also run the Dell diagnostics using the Fn button on startup and passes all the test.

I have sent my service tag via PM.

Thank you

James

Hey, I have posted below. Had exactly the same problems, tried all of the stuff Dell suggested. In the end they had to replace the screen (Under warranty) all fixed now. Hopefully you still have some warranty left on your unit. Good luck!

Hi,

I have the exact same issue with my XPS 15 still on warranty.

Is a screen replacement only resolution to this problem?

Thanks

Sorry it's taken awhile to reply...

1. Safe mode:  flickering lines still present

2. External monitor:  no flickering lines on the monitor

3. LCD BIST - solid colours ok

4. Diagnostics - through the Dell website .. all check out ok

Seems like a fault to me, given what others have been saying who have the same problem. 

I also have developed a problem with the battery ("charging has been disabled") which I cannot seem to fix either - am dependent on the charging lead at the moment.

Hi All,

This has recently started on my XPS 15 as well, definitely sounds like a fault.
