Vertical lines Grey Screen HP Pavillion laptop dv4

[maxinemaxine1]

1) A couple of months ago 3 vertical lines have appeared on left of laptop screen.  Then the last couple of weeks all of a sudden the entire screen turns into a grey color with vertical lines.  Happened three times already and don't know what to do.  Not too computer saavy (I'm a senior) and will bring it in for repair but I don;t want to get cheated and want to be at least knowledgeable on what it might be.  Read something about an inverter (don't know what this means).  When this happens I obviously turn off the pc wait a couple of minutes and turn it back on.  Just do not know what is causing this.

Perhaps I need to change the screen, is this costly?

2) Also I'm on a wireless network and the pages sometimes have a delay in loading or it says it's not connected.  Have called my provider and they do not know what the problem is.  Fox six mos their service worked fine, all of a sudden it doesn't and of course they blame my pc.  Would anyone know why this would happen intermittently ?

Thanks in advance. Appreciate all of your help..........

Hello @maxinemaxine1,

Welcome back to the HP Support Forums!

I came across your post about the display issue, and wanted to help!  I understand that the display have vertical lines, and you are also having trouble with the WiFi.

To start, can you provide me with the Product Number of the notebook?  Here is a link you can use that will help you find your Model and Product Number: HP Customer Support - Products

In the meantime, the issue with the display may be software related.  First, try reviewing the following document, and let me know if it helps:

HP PCs - Error: Display Driver Stopped Responding and Has Recovered (Windows 10, 8, 7)

If it does not, you could try opening the notebook to check the hardware components.  However, based on your knowledge of notebooks, this may not be the best solution.  At that point, you may consider sending the notebook in for repair, or contacting HP Phone Support for repair options.  In regards to the WiFi issue, this can be software related as well.  Try going through the steps in this document, and let me know how it goes:

Reviewed this page and it says NOTHING about the screen going into gray color and turns completely into vertical lines.  Is there something I'm missing or is there a page with an explanation or instructions for this issue?  thanks!

Please just answer the question

What can cause my laptop screen to turn into grey with white lines (kind of mimics the cover of the laptop).  Do not want steps to restart, download or do a complete recovery.  Told you I am not computer saavy on all this.

I am bringing it in for repair just would lie to know some things that may cause this so that I can talk intelligently to them,

Thank you again, appreciate it

Hello @maxinemaxine1,

Thank you for the quick reply!

There can be multiple reasons why you would have this issue.  Software wise, it may be related to Malicious Software.  Or perhaps your drivers need to be updated.  Hardware wise, the Graphics Card may be failing. Or it is possible that the display cable is not connected properly, or is defective.  It is also possible that the display panel it self is damaged.  I hope this helps.

Regards!

HI @maxinemaxine1.

OK I deal with type of issue quiet often. First things first.

1. Try plugging your laptop into an external screen - if you need to know how to do this any tech store should be glad to help to show how this is done. This will determine whether your graphics Card is at Fault. If the external screen has a clear picture and no lines then you will need to have the screen replaced.

2. Internet Wireless reasons of lagging. Generally this can be caused by background software receiving updates and also your windows system. But this a theory for now. Tr

Try running a Registry fixing software and a defrag and see if that fixes your issue. If problem persist try running a malware clean through unit as you may have some nasty bugs causing issue.
