5750g Random horizontal flicker - diagnosis please

Noiseyv

I have, well my daughter uses and wants me to fix, a 5750g which randomly flickers horzontally. The best description I can give is that it is like an old school TV which has lost it sync. The flicker is not in the same position each time and perhaps seems to be related to what is going on on the screen - eg if heavy graphics use - but I am not totally sure. Although I am not epileptic it is very distracting.

 

I have taken the cover off (it is clearly out of warranty) and cannot see anything dodgy in the video cable but am wondering if I should just replace this anyway. But if someone can tell me if it is say, the graphics card and there is nothing I can do then I will know not to bother.

 

It is a shame because the laptop still performs well in other respects.

 

Any ideas about the cause?

Hi,

You could move the screen to different positions while it's flickering, if it stops, then it could be a faulty display cabe, try connecting to an external monitor with HDMI or VGA cable, if you don't see the flickering, you have to replace the screen in your laptop.
