Horizontal flickering static lines on Notebook screen

[MattBurd]

Hi,

For the last couple of days I have been seeing occasionally some horizontal flickering white lines on parts of my screen. The most noticable one is right at the top above the maximised browser window centered. In detail it looks like static lines, white and thin. They are not always there. I cannot be certain but it sometimes appears when I open a window such as browser or documents from the desktop.

I have had this notebook PC for 2 years. The theme used doesnt seem to affect the problem; I have used both 7 aero and windows 7 classic themes but the problem persists every now and then.  There is nothing I can think of that I have downloaded or changed that could have created this problem. I am not too worried about it at present but it can be a bit worrying that sometimes it will happen a lot with a few lines. I can still clearly see the display with the lines present. When taking a screenshot of the problem, the lines do not appear on the screenshot. There have been no physical impacts to the screen or any damage to the laptop itself.

Notebook PC specs:

Windows 7 home premium x64,

HP compaq Presario CQ57,

AMD Vision sticker on the product with Duel Core and AMD radeon graphics card (6310 series)

Processor is e-300 apu at 1.3gHz

4.00 gb RAM (3.60gb useable)

3.4 windows experience index

Service pack 1.

My Video/Graphics drivers are updated (AMD)

Running a Microsoft FixIt doesnt find anything.

I very rarely play hardcore games. It is mainly simulation (not hard core) but havent played games on it any time soon before the problem started occuring.

I have tried to describe the problem as well as possible: Also, I appologise if there are any threads similar to this. Any help would be appricated. I will aim to respond to any replies ASAP. Thanks

Matt

Hi MattBurd, welcome to the HP Forums. You have described your issue very well, thanks for that. If the white lines appear intermittantly, and are not captured with a screen shot it is likely the actual LCD display or its data cable is causing this. If not, perhaps it can be resolved with a hard reset:  Performing a Hard Reset or Forced Reset

If that does not clear it up permanently, you are probably experiencing a hardware failure as previously mentioned. If you are comfortable with this, you can see the display assembly removal instructions begin on page 61 of this:  Compaq Presario CQ57 Notebook PC Maintenance and Service Guide.
